Static dilaton space-time parameters from frequency shifts of photons emitted by geodesic particles
Susana Valdez-Alvarado, Ricardo Becerril, Francisco Astorga
The mass parameter of dilaton space-times is obtained as a function of the redshift-blueshift (zred, zblue) of photons emitted by particles orbiting in circular motion around these…
On the Integrability of the Geodesic Flow on a Friedmann-Robertson-Walker Spacetime
Francisco Astorga, J. Felix Salazar, Thomas Zannias
We study the geodesic flow on the cotangent bundle of a Friedman-Robertson-Walker spacetime (M, g). On this bundle, the HamiltonJacobi equation is completely separable and this sep…
The evolution of a spatially homogeneous and isotropic universe filled with a collisionless gas
Francisco Astorga, Olivier Sarbach, Thomas Zannias
We review the evolution of a spatially homogeneous and isotropic universe described by a Friedmann-Robertson-Walker spacetime filled with a collisionless, neutral, simple, massive…
Equal-time two-point correlation functions in Coulomb gauge Yang-Mills theory
D. Campagnari, A. Weber, H. Reinhardt +2
We apply a functional perturbative approach to the calculation of the equal-time two-point correlation functions and the potential between static color charges to one-loop order in…
Generation of baryon inhomogeneities in the electroweak phase transition
Ariel Megevand, Francisco Astorga
It is known that baryon number inhomogeneities may arise as a consequence of electroweak baryogenesis. Their geometry, size, and amplitude depend on the parameters that characteriz…
Dimensional Reduction, Hard Thermal Loops and the Renormalization Group
C. R. Stephens, Axel Weber, Peter O. Hess +1
We study the realization of dimensional reduction and the validity of the hard thermal loop expansion for lambda phi^4 theory at finite temperature, using an environmentally friend…
