cond-mat/0608023 [abs, ps, pdf, other] :: Title: Relativistic diffusion processes and random walk models
Authors: Jörn Dunkel, Peter Talkner, Peter Hänggi
Comments: v2: thoroughly revised and restructured, relevant changes/additions: central limit theorem-based argument for the non-existence of continuous relativistic Markov processes in position space (Sec. II C), failure of the standard path integral approach in the relativistic case clarified, second relativistic model slightly modified (Sec.III B), main results summarized in Eqs. (24) and (25)

The nonrelativistic standard model for a continuous, one-parameter diffusion process is the Wiener process. As well-known, the Gaussian transition probability density function (PDF) of this process is in conflict with special relativity, as it permits particles to propagate at velocities larger than the speed of light. A frequently considered alternative is provided by the telegraph equation, whose solutions avoid superluminal propagation speeds but suffer from singular diffusion fronts on the light cone, which are unlikely to exist for massive particles. Attempting to avoid such singularities, we discuss non-Markovian relativistic generalizations of the Wiener process by focussing directly on the desired properties of the transition PDFs. This approach yields two types of continuous diffusion models for massive particles which could be used as a viable alternative to the solutions of the telegraph equation.

Authors: Z. G. Huang, H. Q. Lu, W. Fang
Comments: 6 pages, 4 figures

In this paper, we regard dilaton in Weyl-scaled induced gravitational theory as a coupled quintessence. Based on this consideration, we investigate the dilaton coupled quintessence(DCQ) model in $\omega-\omega'$ plane, which is defined by the equation of state parameter for the dark energy and its derivative with respect to $N$(the logarithm of the scale factor $a$). We find the scalar field equation of motion in $\omega-\omega'$ plane, and show mathematically the property of attractor solutions which correspond to $\omega_\sigma\sim-1$, $\Omega_\sigma=1$. Finally, we find that our model is a tracking one which belongs to "freezing" type model classified in $\omega-\omega'$ plane.

In this paper, we investigate the dynamics of Born-Infeld(B-I) phantom model in the $\omega-\omega'$ plane, which is defined by the equation of state parameter for the dark energy and its derivative with respect to $N$(the logarithm of the scale factor $a$). We find the scalar field equation of motion in $\omega-\omega'$ plane, and show mathematically the property of attractor solutions which correspond to $\omega_\phi\sim-1$, $\Omega_\phi=1$, which avoid the "Big rip" problem and meets the current observations well.

Authors: Vincenzo Chilla
Comments: IOP class; 19 pages, 2 figures
Subj-class: Mathematical Physics
MSC-class: 20C35;05E99

Transformation coefficients between standard bases for irreducible representations of the Brauer centralizer algebra $\mathfrak{B}_f(x)$ and split bases adapted to the $\mathfrak{B}_{f_1} (x) \times \mathfrak{B}_{f_2} (x) \subset \mathfrak{B}_f (x)$ subalgebra ($f_1 +f_2 = f$) are considered. After providing the suitable combinatorial background, based on the definition of $i$-coupling relation on nodes of the subduction grid, we introduce a generalized version of the subduction graph which extends the one given in J. Phys. A: Math. Gen. $\mathbf{39}$ 7657-7668 for symmetric groups. Thus, we can describe the structure of the subduction system arising from the linear method and give an outline of the form of the solution space. An ordering relation on the grid is also given and then, as in the case of symmetric groups, the choices of the phases and of the free factors governing the multiplicity separations are discussed.

Subj-class: Instrumentation and Detectors

At the MSU SINP electron accelerator, a space-time dependence of the acoustic pressure generated in water by an electron beam of 50 MeV energy was obtained. Measurements were carried out in 100 points located along the line parallel to the beam axis at the distance of 6.5 cm from the axis. At a two-dimensional diagram (distance-time) two signal tracks were observed from two sound sources: a cylindrical acoustic antenna generated by the electron beam, and an area of the beam entrance cap which divides the water medium from the air.

gr-qc/0610126 [abs, ps, pdf, other] :: Title: Binary black hole spectroscopy
Authors: Chris Van Den Broeck, Anand Sengupta
Comments: 25 pages, many figures

We investigate the effects on parameter estimation of including amplitude corrections to post-Newtonian (PN) gravitational waveforms for the quasi-circular, adiabatic inspiral of binary compact objects. The amplitude-corrected waveforms are superpositions of harmonics of the orbital phase. Their performance is compared with that of the restricted PN waveforms, which only have the dominant harmonic at twice the orbital phase, with no amplitude corrections. For concreteness we consider parameter estimation in the covariance matrix formalism for Advanced LIGO as well as a possible third-generation detector tentatively called EGO. We use the stationary phase approximation to the Fourier transform of waveforms at 2.5PN order in amplitude and in phase, with inclusion of spin-related contributions to the phasing up to 2PN order. It is found that the use of such high-order amplitude-corrected waveforms leads to a dramatic improvement in the quality of parameter estimation. With restricted waveforms the errors are steep functions of the total mass of the binary, and accurate parameter extraction is only possible for relatively light stellar mass binaries. By contrast, at distances of $\sim 100$ Mpc the amplitude-corrected waveforms allow for high-accuracy parameter extraction for total masses up to several hundred solar masses. Other qualitative advantages include the measurability of individual component masses (which are poorly determined with restricted waveforms), and the possibility of finding objects whose spin exceeds the Kerr bound.
gr-qc/0610131 [abs, ps, pdf, other] :: Title: On the accretion-induced QNM excitation of a Schwarzschild black hole
Authors: Alessandro Nagar, Olindo Zanotti, Jose A. Font, Luciano Rezzolla
Comments: 15 pages, 12 figures, submitted to Phys. Rev. D

By combining the numerical solution of the nonlinear hydrodynamics equations with the solution of the linear inhomogeneous Zerilli-Moncrief and Regge-Wheeler equations we investigate the properties of the gravitational radiation emitted during the axisymmetric accretion of matter onto a Schwarzschild black hole. The matter models considered include quadrupolar dust shells and thick accretion disks, permitting us to simulate situations which may be encountered at the end stages of stellar gravitational collapse or binary neutron star merger. We focus on the interference pattern appearing in the energy spectra of the emitted gravitational waves and on the amount of excitation of the quasi-normal modes of the accreting black hole. We show that, quite generically in the presence of accretion, the black hole ringdown is not a simple superposition of quasi-normal modes, although the fundamental mode is usually present and often dominates the gravitational-wave signal. We interpret this as due to backscattering of waves off the non-exponentially decaying part of the black-hole potential and to the finite spatial extension of the accreting matter. Our results suggest that the black-hole QNM contributions to the full gravitational-wave signal should be extremely small and possibly not detectable in generic astrophysical scenarios involving the accretion of extended distributions of matter.

The process of Compton scattering $\gamma e^{\pm} \to \gamma e^{\pm}$ in a strongly magnetized medium of arbitrary temperature and zeroth chemical potential was considered. The analytical expressions for the partial cross section in the small concentration limit of the electron-positron plasma are obtained. The numerical estimations for the partial probabilities of this process are presented by taking into account the photon dispersion in a strong magnetic field and charge-symmetric plasma of arbitrary temperature. The comparision of the scattering probability with photon splitting in a plasma was investigated. The astrophysical applications of the obtaining results are considered.
hep-ph/0610343 [abs, ps, pdf, other] :: Title: Warm inflation dynamics in the low temperature regime
Authors: Mar Bastero-Gil Arjun Berera
Comments: 13 pages, 2 eps figures

Warm inflation scenarios are studied with the dissipative coefficient computed in the equilibrium approximation. Use is made of the analytical expressions available in the low temperature regime with focus on the possibility of achieving strong dissipation within this approximation. Two different types of models are examined: monomial or equivalently chaotic type potentials, and hybrid like models where the energy density during inflation is dominated by the false vacuum. In both cases dissipation is shown to typically increase during inflation and bring the system into the strong dissipative regime. Observational consequences are explored for the amplitude of the primordial spectrum and the spectral index, which translate into constraints on the number of fields mediating the dissipative mechanism, and the number of light degrees of freedom produced during inflation. This paper furthers the foundational development of warm inflation dynamics from first principles quantum field theory by calculating conservative lower bound estimates on dissipative effects during inflation using the well established thermal equilibrium approximation. This approximation does not completely represent the actual physical system and earlier work has shown relaxing both the equilibrium and low temperature constraints can substantially enlarge the warm inflation regime, but these improvements still need further theoretical development.
hep-th/0610211 [abs, ps, pdf, other] :: Title: Precision Cosmology and the Landscape
Authors: Raphael Bousso
Comments: 38 pages, 6 figures. Based on a talk given at the conference in honor of the 90th birthday of Charles Townes (Berkeley, October 2005), and on a colloquium at Stanford University. v2: references improved

After reviewing the cosmological constant problem - why is Lambda not huge? - I outline the two basic approaches that had emerged by the late 1980s, and note that each made a clear prediction. Precision cosmological experiments now indicate that the cosmological constant is nonzero. This result strongly favors the environmental approach, in which vacuum energy can vary discretely among widely separated regions in the universe. The need to explain this variation from first principles constitutes an observational constraint on fundamental theory. I review arguments that string theory satisfies this constraint, as it contains a dense discretuum of metastable vacua. The enormous landscape of vacua calls for novel, statistical methods of deriving predictions, and it prompts us to reexamine our description of spacetime on the largest scales. I discuss the effects of cosmological dynamics, and I speculate that weighting vacua by their entropy production may allow for prior-free predictions that do not resort to explicitly anthropic arguments.

Comments: 8 pages 7 figures

We study the behaviour of five-dimensional fermions localized on branes, which we describe by domain walls, when two parallel branes collide in a five-dimensional Minkowski background spacetime. We find that most fermions are localized on both branes as a whole even after collision. However, how much fermions are localized on which brane depends sensitively on the incident velocity and the coupling constants unless the fermions exist on both branes.

gr-qc/0610154 [abs, ps, pdf, other] :: Title: Total recoil: the maximum kick from nonspinning black-hole binary inspiral
Authors: Jose A. Gonzalez, Ulrich Sperhake, Bernd Bruegmann, Mark Hannam, Sascha Husa
Comments: 4 pages, 4 figures

When unequal-mass black holes merge, the final black hole receives a ``kick'' due to the asymmetric loss of linear momentum in the gravitational radiation emitted during the merger. The magnitude of this kick has important astrophysical consequences. Recent breakthroughs in numerical relativity allow us to perform the largest parameter study undertaken to date in numerical simulations of binary black hole inspirals. We study non-spinning black-hole binaries with mass ratios from $q=M_1/M_2=1$ to $q =0.25$ ($\eta = q/(1 + q)^2$ from 0.25 to 0.16). We accurately calculate the velocity of the kick to within 6\%, and the final spin of the black holes to within 2\%. A maximum kick of $175.70\pm11$ km\,s$^{-1}$ is achieved for a mass ratio of $\eta = 0.195 \pm 0.005$.
hep-ph/0610384 [abs, ps, pdf, other] :: Title: A quantum long time energy red shift: a contribution to varying $\alpha$ theories
Authors: K. Urbanowski
Comments: LaTeX2e, 15 pages
Subj-class: High Energy Physics - Phenomenology; Space Physics

By analyzing the survival probability amplitude of an unstable state we show that the energy corrections to this state in the long ($t \to \infty$) and relatively short (lifetime of the state) time regions, are different. It is shown that in the considered model the above corrections decrease to zero as $t \to \infty$. It is hypothesized that this property could be detected by analyzing the spectra of distant astrophysical objects. The above property of unstable states may influence the measured values of possible deviations of the fine structure constant $\alpha$ as well as other astrophysical and cosmological parameters.

Authors: X.-J. Bi, Y.-Q. Guo, H.-B. Hu, X. Zhang
Comments: 20 pages, 7 figures

In this paper we study the possibility of detecting gamma rays from dark matter annihilation in the subhalos of the Milky Way by the ground based EAS detectors within the frame of the minimal supersymmetric standard model. Based on the N-body simulation of the evolution of the dark matter subhalos and the Monte Carlo simulation of the properties of the ARGO and HAWC detectors, we give the sensitivities of these detectors on the detection of dark matter annihilation. We find the ground EAS detectors have the possibility to observe such signals. Conversely if no signal observed we give the constraints on the supersymmetric parameter space, which strongly depends on the subhalos evolution.

Authors: A. A. Popov, R. K. Muharlyamov
Comments: iopart, 10 pages

The spherically symmetric perturbations in the spatially flat Friedman models are considered. It is assumed that the Friedmannian density and pressure are related through a linear equation of state. The perturbation is joined smoothly with an unperturbed Friedmann's background at the sound horizon of perturbation. Such junction is in accordance with the "birth" of a local perturbation as a result of the redistribution of matter. The solution of the Einstein's equations is obtained in linear approximation on a Friedmann's background near the the sound horizon of perturbation.
hep-th/0610321 [abs, ps, pdf, other] :: Title: Cosmology of the Tachyon in Brane Inflation
Authors: Louis Leblond, Sarah Shandera
Comments: 30 pages, 2 figures

In certain implementations of the brane inflationary paradigm, the exit from inflation occurs when the branes annihilate through tachyon condensation. We investigate various cosmological effects produced by this tachyonic era. We find that only a very small region of the parameter space (corresponding to slow-roll with tiny inflaton mass) allows for the tachyon to contribute some e-folds to inflation. In addition, non-adiabatic density perturbations are generated at the end of inflation. When the brane is moving relativistically this contribution can be of the same order as fluctuations produced 55 e-folds before the end of inflation. The additional contribution is exactly scale-invariant and enhances the tensor/scalar ratio. Additional non-gaussianities will also be generated, sharpening current constraints on DBI-type models which already predict a significantly non-gaussian signal.

Authors: Steven A. Abel, Chong-Sun Chu, Joerg Jaeckel, Valentin V. Khoze
Comments: 16 pages, 3 figures

Supersymmetry breaking in a metastable vacuum is re-examined in a cosmological context. It is shown that thermal effects generically drive the Universe to the metastable minimum even if it begins in the supersymmetry-preserving one. This is a generic feature of the ISS models of metastable supersymmetry breaking due to the fact that SUSY preserving vacua contain fewer light degrees of freedom than the metastable ground state at the origin. These models of metastable SUSY breaking are thus placed on an equal footing with the more usual dynamical SUSY breaking scenarios.

Authors: Zong-Kuan Guo, Nobuyoshi Ohta, Shinji Tsujikawa
Comments: 13 pages

We discuss the realization of inflation and resulting cosmological perturbations in the low-energy effective string theory. In order to obtain nearly scale-invariant spectra of density perturbations and a suppressed tensor-to-scalar ratio, it is generally necessary that the dilaton field $\phi$ is effectively decoupled from gravity together with the existence of a slowly varying dilaton potential. We also study the effect of second-order corrections to the tree-level action which are the sum of a Gauss-Bonnet term coupled to $\phi$ and a kinetic term $(\nabla \phi)^4$. We find that it is possible to realize observationally supported spectra of scalar and tensor perturbations provided that the correction is dominated by the $(\nabla \phi)^4$ term even in the absence of the dilaton potential. When the Gauss-Bonnet term is dominant, tensor perturbations exhibit violent negative instabilities on small-scales about a de Sitter background in spite of the fact that scale-invariant scalar perturbations can be achieved.

A new model for the description of strangelets' behavior in the Earth's atmosphere is presented. Strangelet fission induced by colliding with air nuclei is included. It is shown that strangelets with certain parameters of initial mass and energy may reach depths near the sea level, which can be examined by ground-based experiments.

We derive the expression for the snap parameter in $f(R)$ gravity. We use the Palatini variational principle to obtain the field equations, and regard the Einstein conformal frame as physical. We give the prediction for the present value of the snap parameter for the particular case $f(R)=R-\frac{\alpha^2}{3R}$, which is the simplest $f(R)$ model explaining current acceleration of the universe.

Comments: 14 pages, no figures

We show that if photon possesses a tiny but non-vanishing mass the universe cannot be electrically neutral. Cosmological electric asymmetry could be generated either at an early stage by different evaporation rates of primordial black holes with respect to positively and negatively charged particles or by predominant capture of protons in comparison to electrons by heavy galactic black holes in contemporary universe. An impact of this phenomenon on the generation of large scale magnetic fields and on the universe acceleration is considered.

The original Lindhard-Scharff-Schi{\o}tt (LSS) theory and the more recent Tilinin theory for calculating the nuclear and electronic stopping powers of slow heavy ions are compared with predictions from the SRIM code by Ziegler. While little discrepancies are present for the nuclear contribution to the energy loss, large differences are found in the electronic one. When full ion recoil cascade simulations are tested against the elastic neutron scattering data available in the literature, it can be concluded that the LSS theory is the more accurate.
