Equations of motion in General Relativity and Quantum Mechanics
non-geodesic motion Dirac equation equations of motion Maxwell-Boltzmann distribution

2010/10/21
In a previous article a relationship was established between the linearized metrics of General Relativity associated with geodesics and the Dirac Equation of quantum mechanics. In this paper the exten...
Grand canonical ensembles in general relativity
relativistic Gibbs state Fermi coordinates grand canonical ensemble ideal gas
font style='font-size:12px;'>
2010/12/9
We develop a formalism for general relativistic, grand canonical ensembles in space-times with timelike Killing fields. Using that formalism we derive ideal gas laws, and show how they depend on the g...
TransverseDiff gravity is to scalar-tensor as unimodular gravity is to General Relativity
TransverseDiff gravity scalar-tensor unimodular gravity General Relativity

2010/12/15
Transverse Diffeomorphism (TDiff) theories are well-motivated theories of gravity from the quantum perspective, which are based upon a gauge symmetry principle. The main contribution of this work is t...

2010/3/26
Einstein's general theory of relativity has been tested for the first time over distances nearly as large as the universe itself – and has, in the process, trumped most other alternative theories of g...
Probing modifications of General Relativity using current cosmological observations
General Relativity integrated Sachs-Wolfe weak lensing
font style='font-size:12px;'>
2010/3/9
We test General Relativity (GR) using current cosmological data: the cosmic microwave background (CMB) from WMAP5 (Komatsu et al. 2009), the integrated Sachs-Wolfe (ISW) effect from the cross-correla...
Mass and Angular Momentum in General Relativity
Angular Momentum General Relativity
font style='font-size:12px;'>
2010/3/18
We present an introduction to mass and angular momentum in General Relativity. After briefly reviewing energy-momentum for matter fields, first in the flat Minkowski case (Special Relativity) and then...
The Robertson-Walker Metric in a Pseudo-Complex General Relativity
Walker metric energy-momentum
font style='font-size:12px;'>
2010/3/18
We investigate the consequences of the pseudo-complex General Relativity within a pseudo-complexified Roberston-Walker metric. A contribution to the energy-momentum tensor arises, which corresponds to...
Spacetime Brout-Englert-Higgs effect in General Relativity interacting with p-brane matter
Brout-Englert-Higgs p-brane matter
font style='font-size:12px;'>
2010/3/19
We review the manifestation of the Brout-Englert-Higgs effect in general relativity interacting with point-like and extended objects (p-branes including string for p=1 and membrane for p=2), which man...
Expanding Universe and its manifestations beyond the General Relativity
Expanding Universe General Relativity
font style='font-size:12px;'>
2010/3/18
It has been demonstrated that a modern stage of the Universe expansion may be described in accordance with the observations within the scope of the space-time conformal geometry. The clock synchroniza...
On possible a-priori "imprinting" of General Relativity itself on the performed Lense-Thirring tests with LAGEOS satellites
Experimental studies of gravity Satellite orbits Harmonics of the gravity potential field
font style='font-size:12px;'>
2010/3/18
The impact of possible a-priori "imprinting" effects of general relativity itself on recent attempts to measure the Lense-Thirring precessions with the LAGEOS satellites orbiting the Earth and the ter...
Coarse-graining of inhomogeneous dust flow in General Relativity via isometric embeddings
inhomogeneous dust flow isometric embeddings
font style='font-size:12px;'>
2010/3/17
We present a new approach to coarse-graining of variables describing dust flow in GR. It is based on assigning quasi-local shear, twist and expansion to 2-dimensional surfaces with the help of isometr...
Tilted Bianchi Type I dust fluid magnetized cosmological model in general relativity
Bianchi type I dust fluid tilted models
font style='font-size:12px;'>
2010/4/8
Tilted Bianchi Type I perfect fluid cosmological model in presence of magnetic field is investigated. To get a determinate solution, we assume p = 0 and A = BC, where A, B and C are metric potentials....
On the breakdown criterion in General Relativity
General Relativity breakdown criterion
font style='font-size:12px;'>
2014/4/3
In collaboration with I. Rodnianski we give a geometric criterion for the breakdown of an Einstein vacuum space-time foliated by a constant mean curvature, or maximal, foliation. More precisely we sho...
