gr-qc/0608059 [abs, ps, pdf, other] :: Title: Propagation of a string across the cosmological singularity
Authors: Przemyslaw Malkiewicz, Wlodzimierz Piechocki
Comments: 9 pages, 2 figures, revtex4; version accepted for publication in Class. Quantum Grav

Our results concern the transition of a quantum string through the singularity of the compactified Milne (CM) space. We restrict our analysis to the string winding around the compact dimension (CD) of spacetime. The CD undergoes contraction to a point followed by re-expansion. We demonstrate that both classical and quantum dynamics of considered string are well defined. Most of presently available calculations strongly suggest that the singularity of a time dependent orbifold is useless as a model of the cosmological singularity. We believe that our results bring, to some extent, this claim into question.

Authors: Diana V. Shopova, Dimo I. Uzunov
Comments: 41 pages, 4 figs., Chapter in the book: ``Superconductivity Research Advances'' (Nova Science Publ., N. Y., 2007 - in preparation)
Subj-class: Superconductivity; Statistical Mechanics; Strongly Correlated Electrons

Gauge effects on the fluctuation properties of the normal-to-superconducting phase transition in bulk and thin film superconductors are reviewed. Similar problems in the description of other natural systems (liquid crystals, quantum field theory, early universe) are also discussed. The relatively strong gauge effects on the fluctuations of the ordering field at low spatial dimensionality $D$ and, in particular, in thin (quasi-2D) films are considered in details. A special attention is paid to the fluctuations of the gauge field. It is shown that the mechanism, in which these gauge fluctuations affect the phase transition order and other phase transition properties varies with the variation of spatial dimensionality $D$. The problem for the experimental confirmation of theoretical predictions about the order of phase transitions in gauge systems is discussed. Related topics: gauge effects on the critical behavior of unconventional superconductors, disorder, quantum fluctuations in a close vicinity of ultra-low phase transition temperatures, are also briefly discussed.

hep-th/0612217 [abs, ps, pdf, other] :: Title: 1/R multidimensional gravity with form-fields: stabilization of extra dimensions, cosmic acceleration and domain walls
Authors: Tamerlan Saidov, Alexander Zhuk
Comments: 10 pages, revtex, 5 eps figures

We study multidimensional gravitational models with scalar curvature nonlinearity of the type 1/R and with form-fields (fluxes) as a matter source. It is assumed that the higher dimensional space-time undergoes Freund-Rubin-like spontaneous compactification to a warped product manifold. It is shown that for certain parameter regions the model allows for a freezing stabilization of the internal space near the positive minimum of the effective potential which plays the role of the positive cosmological constant. This cosmological constant provides the observable late-time accelerating expansion of the Universe if parameters of the model is fine tuned. Additionally, the effective potential has the saddle point. It results in domain walls in the Universe. We show that these domain walls do not undergo inflation.

Comments: 5 pages, to appear in the proceedings of the 2006 International School of Subnuclear Physics in Erice and in ''Young Scientists'' online-only supplement of the European Physical Journal C-Direct (Springer)

We show that quantum mechanics and general relativity imply the existence of a minimal length. To be more precise, we show that no operational device subject to quantum mechanics, general relativity and causality could exclude the discreteness of spacetime on lengths shorter than the Planck length. We then consider the fundamental limit coming from quantum mechanics, general relativity and causality on the precision of the measurement of a length.
hep-th/0701111 [abs, ps, pdf, other] :: Title: Conceptual Problems of Inflationary Cosmology and a New Approach to Cosmological Structure Formation
Authors: Robert H. Brandenberger
Comments: 33 pages, 4 figures Based on an invited talk at "Inflation + 25", Paris, June 2006 To be published in the proceedings (Springer, 2007)

In spite of its great phenomenological success, current models of scalar field-driven inflation suffer from important unresolved conceptual issues. New fundamental physics will be required to address these questions. String theory is a candidate for a unified quantum theory of all four forces of nature. As will be shown, string theory may lead to a cosmological background quite different from an inflationary cosmology, and may admit a new stringy mechanism for the origin of a roughly scale-invariant spectrum of cosmological fluctuations.

Authors: Leor Barack, Norichika Sago
Comments: 31 pages, 17 figures

We calculate the gravitational self force acting on a pointlike test particle of mass $\mu$, set in a circular geodesic orbit around a Schwarzschild black hole. Our calculation is done in the Lorenz gauge: For given orbital radius, we first solve directly for the Lorenz-gauge metric perturbation using numerical evolution in the time domain; We then compute the (finite) back-reaction force from each of the multipole modes of the perturbation; Finally, we apply the ``mode sum'' method to obtain the total, physical self force. The {\em temporal} component of the self force (which is gauge invariant) describes the dissipation of orbital energy through gravitational radiation. Our results for this component are consistent, to within the computational accuracy, with the total flux of gravitational-wave energy radiated to infinity and through the event horizon. The {\em radial} component of the self force (which is gauge dependent) is calculated here for the first time. It describes a conservative shift in the orbital parameters away from their geodesic values. We thus obtain the $O(\mu)$ correction to the energy and angular momentum parameters (in the Lorenz gauge), as well as the $O(\mu)$ shift in the orbital frequency (which is gauge invariant).

Journal-ref: General Relativity and Gravitation (1999) 31, 357-369

We discuss the general-relativistic contributions to occur in the electromagnetic properties of a superconductor with a heat flow. The appearance of general-relativistic contribution to the magnetic flux through a superconducting thermoelectric bimetallic circuit is shown. A response of the Josephson junctions to a heat flow is investigated in the general-relativistic framework. Some gravitothermoelectric effects which are observable in the superconducting state in the Earth's gravitational field are considered.

Comments: Latex file. To appear in Int.J.Mod.Phys.D
Subj-class: General Relativity and Quantum Cosmology; Space Physics

The decreasing of the inertial mass density, established in the past for dissipative fluids, is found to be produced by the ``inertial'' term of the transport equation. Once the transport equation is coupled to the dynamical equation one finds that the contribution of the inertial term diminishes the effective inertial mass and the ``gravitational'' force term, by the same factor. An intuitive picture, and prospective applications of this result to astrophysical scenarios are discussed.
gr-qc/0701074 [abs, ps, pdf, other] :: Title: Particle vs. future event horizon in interacting holographic dark energy model
Authors: H. Mohseni Sadjadi
Comments: 11 pages, 2 figures

By choosing the future event horizon as the horizon of the flat FLRW universe, we show that although the interacting holographic dark energy model is able to explain the phantom divide line crossing, but the thermodynamics second law is not respected in this model. We show that if one takes the particle event horizon as the horizon of the universe, besides describing w=-1 crossing in a consistent way with thermodynamics second law, he is able to alleviate the coincidence problem. By this choice, the first and second coincidence problems may be solved in a same framework. In this approach, after the first transition from quintessence to phantom, there is another transition from phantom to quintessence phase which avoids the big rip singularity

We show that under gravity the effective masses for neutrino and antineutrino are different which opens a possible window of neutrino-antineutrino oscillation even if the rest masses of the corresponding eigenstates are same. This is due to CPT violation and possible to demonstrate if the neutrino mass eigenstates are expressed as a combination of neutrino and antineutrino eigenstates, as of the neutral kaon system, with the plausible breaking of lepton number conservation. In early universe, in presence of various lepton number violating processes, this oscillation might lead to neutrino-antineutrino asymmetry which resulted baryogenesis from the B-L symmetry by electro-weak sphaleron processes. On the other hand, for Majorana neutrinos, this oscillation is expected to affect the inner edge of neutrino dominated accretion disks around a compact object by influencing the neutrino sphere which controls the accretion dynamics, and then the related type-II supernova evolution and the r-process nucleosynthesis.
hep-ph/0612374 [abs, ps, pdf, other] :: Title: Additional bounds on the pre Big--Bang--Nucleosynthesis Expansion by means of $\gamma$-rays from the Galactic Center
Authors: F. Donato, N. Fornengo, M. Schelke
Comments: 9 pages, 6 figures

The possibility to use $\gamma$--ray data from the Galactic Center (GC) to constrain the cosmological evolution of the Universe in a phase prior to primordial nucleosyntesis, namely around the time of cold dark matter (CDM) decoupling, is analyzed. The basic idea is that in a modified cosmological scenario, where the Hubble expansion rate is enhanced with respect to the standard case, the CDM decoupling is anticipated and the relic abundance of a given dark matter (DM) candidate enhanced. This implies that the present amount of CDM in the Universe may be explained by a Weakly Interacting Massive Particle (WIMP) which possesses annihilation cross section (much) larger than in standard cosmology. This enhanced annihilation implies larger fluxes of indirect detection signals of CDM. We show that the HESS measurements can set bounds for WIMPs heavier than a few hundreds of GeV, depending on the actual DM halo profile. These results are complementary to those obtained in a previous analysis based on cosmic antiprotons. For a Moore DM profile, $\gamma$--ray data limit the maximal Hubble rate enhancement to be below a factor of 100. Moreover, a WIMP heavier than 1 TeV is not compatible with a cosmological scenario with enhanced expansion rate prior to Big Bang Nucleosynthesis (BBN). Less steep DM profiles provide less stringent bounds, depending of the cosmological scenario.

gr-qc/0701070 [abs, ps, pdf, other] :: Title: The Ups and Downs of Cyclic Universes
Authors: T. Clifton, John D. Barrow
Comments: 15 pages, 4 figures

We investigate homogeneous and isotropic oscillating cosmologies with multiple fluid components. Transfer of energy between these fluids is included in order to model the effects of non-equilibrium behavior on closed universes. We find exact solutions which display a range of new behaviors for the expansion scale factor. Detailed examples are studied for the exchange of energy from dust or scalar field into radiation. We show that, contrary to expectation, it is unlikely that such models can offer a physically viable solution to the flatness problem.
gr-qc/0701087 [abs, ps, pdf, other] :: Title: The Einstein-Elko system -- Can dark matter drive inflation?
Authors: C. G. Boehmer
Comments: 24 pages

Recently, a spin one half matter field with mass dimension one was discovered, called Elko spinors. The present work shows how to introduce these fields into a curved spacetime by the standard covariantisation scheme. After formulating the coupled Einstein-Elko field equations, the spacetime is assumed to be homogeneous and isotropic in order to simplify the resulting field equations. Analytical ghost Elko solutions are constructed which have vanishing energy-momentum tensor without and with cosmological constant. The cosmological Elko theory is finally related to the standard scalar field theory with self interaction that gives rise to inflation and it is pointed out that the Elko spinors are not only prime dark matter candidates but also prime candidates for inflation.
gr-qc/0701090 [abs, ps, pdf, other] :: Title: Cosmologies with variable parameters and dynamical cosmon: implications on the cosmic coincidence problem
Authors: Javier Grande, Joan Sola, Hrvoje Stefancic
Comments: LaTeX, 13 pages, 5 figures

Dynamical dark energy (DE) has been proposed to explain various aspects of the cosmological constant (CC) problem(s). For example, it is very difficult to accept that a strictly constant Lambda-term constitutes the ultimate explanation for the DE in our Universe. It is also hard to acquiesce in the idea that we accidentally happen to live in an epoch where the CC contributes an energy density value right in the ballpark of the rapidly diluting matter density. It should perhaps be more plausible to conceive that the vacuum energy, is actually a dynamical quantity as the Universe itself. More generally, we could even entertain the possibility that the total DE is in fact a mixture of vacuum energy and other dynamical components (e.g. fields, higher order terms in the effective action etc) which can be represented collectively by an effective entity X (dubbed the ``cosmon''). The ``cosmon'', therefore, acts as a dynamical DE component different from the vacuum energy. While it can actually behave phantom-like by itself, the overall DE fluid may effectively appear as standard quintessence, or even mimic at present an almost exact CC behavior. Thanks to the versatility of such cosmic fluid we can show that a composite DE system of this sort (``LXCDM'') may have a key to resolving the mysterious coincidence problem.
hep-th/0701047 [abs, ps, pdf, other] :: Title: Improved Approximations for Fermion Pair Production in Inhomogeneous Electric Fields
Authors: Sang Pyo Kim, Don N. Page
Comments: RevTex, 12 pages, two figures

Reformulating the instantons in a complex plane for tunneling or transmitting states, we calculate the pair-production rate of charged fermions in a spatially localized electric field, illustrated by the Sauter electric field E_0 sech^2 (z/L), and in a temporally localized electric field such as E_0 sech^2 (t/T). The integration of the quadratic part of WKB instanton actions over the frequency and transverse momentum leads to the pair-production rate obtained by the worldline instanton method, including the prefactor, of Phys. Rev. D72, 105004 (2005) and D73, 065028 (2006). It is further shown that the WKB instanton action plus the next-to-leading order contribution in spinor QED equals the WKB instanton action in scalar QED, thus justifying why the WKB instanton in scalar QED can work for the pair production of fermions. Finally we obtain the pair-production rate in a spatially localized electric field together with a constant magnetic field in the same direction.

Authors: Walter D. Goldberger
Comments: Proceedings of Les Houches 2006. LaTeX, 44 pages, 10 figures

These lectures give an overview of the uses of effective field theories in describing gravitational radiation sources for LIGO or LISA. The first lecture reviews some of the standard ideas of effective field theory (decoupling, matching, power counting) mostly in the context of a simple toy model. The second lecture sets up the problem of calculating gravitational wave emission from non-relativistic binary stars by constructing a tower of effective theories that separately describe each scale in the problem: the internal size of each binary constituent, the orbital separation, and the wavelength of radiated gravitons.

Authors: F. Briscese, E. Elizalde, S. Nojiri, S. D. Odintsov
Comments: LaTeX file, 9 pages. Some references are added. The version to appear in Physcs Letters B

It is shown that phantom scalar models can be mapped into a mathematically equivalent, modified $F(R)$ gravity, which turns out to be complex, in general. Only for even scalar potentials is the ensuing modified gravity real. It is also demonstrated that, even in this case, modified gravity becomes complex at the region where the original phantom dark energy theory develops a Big Rip singularity. A number of explicit examples are presented which show that these two theories are not completely equivalent, from the physical viewpoint. This basically owes to the fact that the physical metric in both theories differ in a time-dependent conformal factor. As a result, an FRW accelerating solution, or FRW instanton, in the scalar-tensor theory may look as a deccelerating FRW solution, or a non-instantonic one, in the corresponding modified gravity theory.

Subj-class: Plasma Physics; Space Physics

The nature of current sheet formation in the vicinity of three-dimensional magnetic null points is investigated. The particular focus is upon the effect of the compressibility of the plasma on the qualitative and quantitative properties of the current sheet. It is found that as the incompressible limit is approached, the collapse of the null point is suppressed, and instead an approximately planar current sheet aligned to the fan plane is present. Both the peak current and peak reconnection rate are reduced. The results imply that previous analytical solutions for steady-state reconnection at fan current sheets are dynamically accessible, while spine current sheet solutions are not.
