gr-qc/0605045 [abs, ps, pdf, other] :: Title: Covariance properties and regularization of conserved currents in tetrad gravity
Authors: Yuri N. Obukhov, Guillermo F. Rubilar
Comments: 37 pages, Revtex, no figures

We discuss the properties of the gravitational energy-momentum 3-form within the tetrad formulation of general relativity theory. We derive the covariance properties of the quantities describing the energy-momentum content under Lorentz transformations of the tetrad. As an application, we consider the computation of the total energy (mass) of some exact solutions of Einstein's general relativity theory which describe compact sources with asymptotically flat spacetime geometry. As it is known, depending on the choice of tetrad frame, the formal total integral for such configurations may diverge. We propose a natural regularization method which yields finite values for the total energy-momentum of the system and demonstrate how it works on a number of explicit examples.

Authors: Patrick Peter (IAP, France), Emanuel J. C. Pinho, Nelson Pinto-Neto (CBPF, Brazil)
Comments: 12 pages, 5 figures, to appear in Phys. Rev. D (2006)

We discuss the gravitational wave background produced by bouncing models based on a full quantum evolution of a universe filled with a perfect fluid. Using an ontological interpretation for the background wave function allows us to solve the mode equations for the tensorial perturbations, and we find the spectral index as a function of the fluid equation of state.

Authors: Beatriz Gato-Rivera
Comments: Chapter of the book `Trends in General Relativity and Quantum Cosmology', Nova Science Eds, New York, 2006, with several minor improvements
Subj-class: Popular Physics; Space Physics

The Fermi Paradox is discussed in the light of the inflationary and brane world cosmologies. We conclude that some brane world cosmologies may be of relevance for the problem of civilizations spreading across our galaxy, strengthening the Fermi Paradox, but not the inflationary cosmologies, as has been proposed.

gr-qc/0605074 [abs, ps, pdf, other] :: Title: A Unified View of the Basic Forces
Authors: Naresh Dadhich (IUCAA, Pune)
Comments: 4 pages, latex, To appear in Proceedings of the Einstein Centennial Maeting, University of Kwazulu-Natal, Durban, Sept. 25-26, 2005

In this essay we wish to seek a unifying thread between the basic forces. We propose that there exists a universal force which is shared by all that physically exists. Universality is characterized by the two properties: (i) universal linkage and (ii) long range. They uniquely identify Einstein gravity as the unversal force. All other forces then arise as these properties are peeled off. For instance, relaxing (i) but retaining (ii) will lead to Maxwell electromagnetic force. This unified outlook makes interesting suggestions and predictions: if there exists a new force, it can only be a short range non-abelian vector or a scalar field, and there should exist in an appropriate space duality relations between weak and electric, and between strong and gravity.

Journal-ref: Phys.Lett. B633 (2006) 368-374

We discuss effective interactions among brane matter induced by modifications of higher dimensional Einstein gravity via the replacement of Einstein-Hilbert term with a generic function f(R) of the curvature scalar R. After deriving the graviton propagator, we analyze impact of virtual graviton exchanges on particle interactions, and conclude that f(R) gravity effects are best probed by high-energy processes involving massive gauge bosons, heavy fermions or the Higgs boson. We perform a comparative analysis of the predictions of f(R) gravity and of Arkani-Hamed-Dvali-Dimopoulos (ADD) scenario, and find that the former competes with the latter when f''(0) is positive and comparable to the fundamental scale of gravity in higher dimensions. In addition, we briefly discuss graviton emission from the brane as well as its decays into brane-localized matter, and find that they hardly compete with the ADD expectations. Possible existence of higher-curvature gravitational interactions in large extra spatial dimensions opens up various signatures to be confronted with existing and future collider experiments.

Journal-ref: Phys.Lett. B635 (2006) 343-349

We discuss effective interactions among brane matter induced by modifications of higher dimensional Einstein gravity through the replacement of Einstein-Hilbert term with a generic function f(R, R_AB R^AB, R_ABCD R^ABCD) of the curvature tensors. We determine gravi-particle spectrum of the theory, and perform a comparative analysis of its predictions with those of the Einstein gravity within Arkani-Hamed--Dvali--Dimopoulos (ADD) setup. We find that this general higher-curvature quantum gravity theory contributes to scatterings among both massive and massless brane matter (in contrast to much simpler generalization of the Einstein gravity, f(R), which influences only the massive matter), and therefore, can be probed via various scattering processes at present and future colliders and directly confronted with the ADD expectations. In addition to collision processes which proceed with tree-level gravi-particle exchange, effective interactions among brane matter are found to exhibit a strong sensitivity to higher-curvature gravity via the gravi-particle loops. Furthermore, particle collisions with missing energy in their final states are found to be sensitive to additional gravi-particles not found in Einstein gravity. In general, road to a correct description of quantum gravity above Fermi energies depends crucially on if collider and other search methods end up with a negative or positive answer for the presence of higher-curvature gravitational interactions.
hep-th/0605071 [abs, ps, pdf, other] :: Title: Non-Gravitating Scalars and Spacetime Compactification
Authors: Durmus A. Demir, Beyhan Pulice
Comments: 18 pp, 1 fig

We discuss role of partially gravitating scalar fields, scalar fields whose energy-momentum tensors vanish for a subset of dimensions, in dynamical compactification of a given set of dimensions. We show that the resulting spacetime exhibits a factorizable geometry consisting of usual four-dimensional spacetime with full Poincare invariance times a manifold of extra dimensions whose size and shape are determined by the scalar field dynamics. Depending on the strength of its coupling to the curvature scalar, the vacuum expectation value (VEV) of the scalar field may or may not vanish. When its VEV is zero the higher dimensional spacetime is completely flat and there is no compactification effect at all. On the other hand, when its VEV is nonzero the extra dimensions get spontaneously compactified. The compactification process is such that a bulk cosmological constant is utilized for curving the extra dimensions.
hep-th/0605105 [abs, ps, pdf, other] :: Title: Why there is something so close to nothing: towards a fundamental theory of the cosmological constant
Authors: Vishnu Jejjala, Djordje Minic
Comments: 19 pages, LaTeX

The cosmological constant problem is turned around to argue for a new foundational physics postulate underlying a consistent quantum theory of gravity and matter, such as string theory. This postulate is a quantum equivalence principle which demands a consistent gauging of the geometric structure of canonical quantum theory. We argue that string theory can be formulated to accommodate such a principle, and that in such a theory the observed cosmological constant is a fluctuation about a zero value. This fluctuation arises from an uncertainty relation involving the cosmological constant and the effective volume of spacetime. The measured, small vacuum energy is dynamically tied to the large size of the universe, thus violating naive decoupling between small and large scales. The numerical value is related to the scale of cosmological supersymmetry breaking, supersymmetry being needed for a non-perturbative stability of local Minkowski spacetime regions in the classical regime.

Authors: Henrik Aratyn, Johan van de Leur
Comments: 32 pages, no figures
Subj-class: Exactly Solvable and Integrable Systems; Mathematical Physics

We use a Grassmannian framework to define multi-component tau functions as expectation values of certain multi-component fermi operators satisfying simple bilinear commutation relations on Clifford algebra. The tau functions depend on both positive and negative flows and are shown to satisfy the 2n-component KP hierarchy. The hierarchy equations can be formulated in terms of pseudo-differential equations for n x n-matrix wave functions derived in terms of tau functions. These equations are cast in form of Sato-Wilson relations. A reduction process leads to the AKNS, two-component Camassa-Holm and Cecotti-Vafa models and the formalism provides simple formulas for their solutions.

Authors: Claudia de Rham, Andrew J. Tolley
Comments: 14 pages +appendices

We propose a simple higher-derivative braneworld gravity model which contains a stable accelerating branch, in the absence of cosmological constant or potential, that can be used to describe the late time cosmic acceleration. This model has similar qualitative features to that of Dvali-Gabadadze-Porrati, such as the recovery of four-dimensional gravity at subhorizon scales, but unlike that case, the graviton zero mode is massless and there are no linearized instabilities. The acceleration rather is driven by bulk gravity in the form of a spin-two ghost condensate. We show that this model can be consistent with cosmological bounds and tests of gravity.

gr-qc/0311085 [abs, ps, pdf, other] :: Title: Magnetic tension and gravitational collapse
Authors: Christos G. Tsagas (AUT)
Comments: Revised and updated version, to appear in CQG

The gravitational collapse of a magnetised medium is investigated by studying qualitatively the convergence of a timelike family of non-geodesic worldlines in the presence of a magnetic field. Focusing on the field's tension we illustrate how the winding of the magnetic forcelines due to the fluid's rotation assists the collapse, while shear-like distortions in the distribution of the field's gradients resist contraction. We also show that the relativistic coupling between magnetism and geometry, together with the tension properties of the field, lead to a magneto-curvature stress that opposes the collapse. This tension stress grows stronger with increasing curvature distortion, which means that it could potentially dominate over the gravitational pull of the matter. If it so happens, a converging family of non-geodesic lines can be prevented from focusing without violating the standard energy conditions.

Authors: Frederic Henry-Couannier (CPPM), André Tilquin (CPPM), Anne Ealet (CPPM), Charling Tao (CPPM)

It has been shown that in the context of General Relativity (GR) enriched with a new set of discrete symmetry reversal conjugate metrics, negative energy states can be rehabilitated while avoiding the well-known instability issues. We review here some cosmological implications of the model and confront them with the supernovae and CMB data. The predicted flat universe constantly accelerated expansion phase is found to be in rather good agreement with the most recent cosmological data.

Authors: Sam Dolan, Chris Doran, Anthony Lasenby
Comments: 34 pages, 12 figures, submitted to Phys Rev D

We study the scattering of massive spin-half waves by a Schwarzschild black hole using analytical and numerical methods. We begin by extending a recent perturbation theory calculation to next order to obtain Born series for the differential cross section and Mott polarization, valid at small couplings. We continue by deriving an approximation for glory scattering of massive spinor particles by considering classical timelike geodesics and spin precession. Next, we formulate the Dirac equation on a black hole background, and outline a simple numerical method for finding partial wave series solutions. Finally, we present our numerical calculations of absorption and scattering cross sections and polarization, and compare with theoretical expectations.
gr-qc/0605066 [abs, ps, pdf, other] :: Title: Why Gravitational Contraction Must be Accompanied by Emission of Radiation Both in Newtonian and Einstein Gravity
Authors: Abhas Mitra
Comments: 8 pages

Helmholtz and Kelvin sowed that the contraction of a bound self-gravitating system must be accompanied by release of radiation energy irrespective of the details of the contraction process because the total Newtonian energy of the system E_N decreases for such contraction. In the era of General Relativity (GR) too, it is justifiably believed that gravitational contraction must release radiation energy. However no GR version of Helmholtz-Kelvin (HK) process has ever been derived. On the other hand, the same Newtonian form of the HK process is used by replacing the relevant quantities by the GR proper values. Here, for the first time, we derive the GR version of this important astrophysical process by simply equating the well known expressions for the gravitational mass (Schwarzschild Mass) and the Inertial Mass (time component of linear momentum) of a spherically symmetric static fluid. Though the resultant equations are different from their presumed form (used so far), GR KH theorem indeed shows that gravitational contraction raises the internal energy of the fluid and simultaneously causes it to radiate. As an offshoot of this exercise, we obtain the GR counterpart of ``binding energy'' of the fluid from the view point of global energy conservation. It may be emphasized that neither the notion of the GR Binding Energy nor any other relevant global quantity obtained here is due to any newly adopted theoretical assumption or perspectives. On the other hand, all such interpretations simply follow from the equality of the ``gravitational mass'' and ``inertial mass'' of the spherically symmetric static fluid. Existence of this GR HK process asserts that, in Einstein gravity too, gravitational collapse must be accompanied by emission of radiation irrespective of the details of the collapse process.
gr-qc/0605094 [abs, ps, pdf, other] :: Title: Generalized Friedmann Equations for a Finite Thick Brane
Authors: S. Ghassemi, S. Khakshournia, R. Mansouri
Comments: 13 pages

We present the generalized Friedmann equations describing the cosmological evolution of a finite thick brane immeresed in a five-dimensional Schwarzschild Anti-de Sitter spacetime. A linear term in the density in addition to a quatratic one arises in the Friedmann equation, leading to the standard cosmological evolution at late times without introducing an ad hoc tension term for the brane. The effective four-dimensional cosmological constant is then uplifted similar to the KKLT effect and vanishes for a brane thickness equal to the AdS curvature size, up to the third order of the thickness. The four-dimensional gravitational constant is then equal to the five-dimensional one divided by the AdS curvature radius, similar to that derived by dimensional compactification. An accelerating brane cosmology may emerge at late times provided there is either a negative transverse pressure component in the brane energy-momentum tensor or the effective brane cosmological constant is positive.
gr-qc/0605100 [abs, ps, pdf, other] :: Title: Imprints of Relic Gravitational Waves in Cosmic Microwave Background Radiation
Authors: D. Baskaran, L. P. Grishchuk, A. G. Polnarev
Comments: 61 pages including 15 figures

A strong variable gravitational field of the very early Universe inevitably generates relic gravitational waves by amplifying their zero-point quantum oscillations. We begin our discussion by contrasting the concepts of relic gravitational waves and inflationary `tensor modes'. We explain and summarize the properties of relic gravitational waves that are needed to derive their effects on CMB temperature and polarization anisotropies. The radiation field is characterized by four invariants I, V, E, B. We reduce the radiative transfer equations to a single integral equation of Voltairre type and solve it analytically and numerically. We formulate the correlation functions C^{XX'}_{\ell} for X, X'= T, E, B and derive their amplitudes, shapes and oscillatory features. Although all of our main conclusions are supported by exact numerical calculations, we obtain them, in effect, analytically by developing and using accurate approximations. We show that the TE correlation at lower \ell's must be negative (i.e. an anticorrelation), if it is caused by gravitational waves, and positive if it is caused by density perturbations. This difference in TE correlation may be a signature more valuable observationally than the lack or presence of the BB correlation, since the TE signal is about 100 times stronger than the expected BB signal. We discuss the detection by WMAP of the TE anticorrelation at \ell \approx 30 and show that such an anticorrelation is possible only in the presence of a significant amount of relic gravitational waves (within the framework of all other common assumptions). We propose models containing considerable amounts of relic gravitational waves that are consistent with the measured TT, TE and EE correlations.

John N. Bahcall championed solar neutrino physics for many years. Thanks to his pioneering and long-lasting contributions, this field of research has not only reached maturity, but has also opened a new window on physics beyond the standard electroweak model through the phenomenon of neutrino flavor oscillations. We briefly outline some recent accomplishments in the field, and also discuss a couple of issues that do not seem to fit in the ``standard picture,'' namely, the chemical controversy at the solar surface, and possible implications of recent gallium radioactive source experiments.
