Superfluid 3He, since its discovery by Osheroff, Richardson and Lee in 1972, has become one of the main systems for experimental studies of quantum field theories. This is due to the very rich order parameter of the quantum ...
A class of exact spherically symmetrical retarded self-similar solutions linearized around the Friedmann background of the Einstein equations is derived and examined for an ideal liquid with an arbitrary barotropy index. ...
The evolution of a superthermal relict plasma component is studied using a nonequilibrium model of the Universe [1] and a kinetic equation of the Fokker-Planck type [2]. Given is the evidence of two maxima in the distribution ...
Introducing an effective refraction index of an Isotropic cosmic medium, we investigate the cosmological fluid dynamics which is consistent with a conformal, timelike symmetry of a corresponding "optical" metric. We ...
A new exactly solvable model for the evolution of a relativistic kinetic system interacting with an internal stochastic reservoir under the influence of a gravitational background expansion is established. This model of ...
This research is an extension of the author's works, in which conformally invariant generalization of string theory was suggested to higher-dimensional objects. Special cases of the proposed theory are Einstein's theory ...
We study the universe evolution starting from the sub-Planckian scale to present times. The requirement for an exponential expansion of the space with the observed metric as a final stage leads to significant restrictions ...
