Causal Bulk Viscous Dissipative Isotropic Cosmologies with Variable Gravitational and Cosmological Constants

M. K. Mak, J. A. Belinchon, T. Harko

We consider the evolution of a flat Friedmann-Robertson-Walker Universe, filled with a causal bulk viscous cosmological fluid, in the presence of variable gravitational and cosmolo…

Renormalization Group Approach to Causal Viscous Cosmological Models

J. A. Belinchon, T. Harko, M. K. Mak

The renormalization group method is applied to the study of homogeneous and flat Friedmann-Robertson-Walker type Universes, filled with a causal bulk viscous cosmological fluid. Th…

Composition of Lorentz Transformations in Terms of Their Generators

B. Coll, F. San Jose Martinez

Two-forms in Minkowski space-time may be considered as generators of Lorentz transformations. Here, the covariant and general expression for the composition law (Baker-Campbell-Hau…

Diffraction-free and dispersion-free pulsed beam propagation in dispersive media

Miguel A. Porras

Pulsed Bessel beams of light propagating in free-space experience diffraction effects that resemble those of anomalous dispersion on pulse propagation. It is then shown that a puls…

Wheeler-DeWitt Equation with Variable Constants

José Antonio Belinchón

In this paper we study how all the physical "constants" vary in the framework described by a model in which we have taken into account the generalize conservation principle for its…

Localization properties of groups of eigenstates in chaotic systems

D. A. Wisniacki, F. Borondo, E. Vergini +1

In this paper we study in detail the localized wave functions defined in Phys. Rev. Lett. {\bf 76}, 1613 (1994), in connection with the scarring effect of unstable periodic orbits…
