Evolution of density and velocity profiles of dark matter and dark energy in spherical voids
Bohdan Novosyadlyj, Maksym Tsizh, Yurij Kulinich
We analyse the evolution of cosmological perturbations which leads to the formation of large isolated voids in the Universe. We assume that initial perturbations are spherical and…
Quantum phase transitions: The mean-field perspective
Johannes Richter, Oleg Derzhko
To illustrate a simple mean-field-like approach for examining quantum phase transitions we consider the quantum Heisenberg antiferromagnet on a square lattice. The exc…
Beyond mean-field properties of binary dipolar Bose mixtures at low temperatures
Volodymyr Pastukhov
We rigorously analyze the low-temperature properties of homogeneous three-dimensional two-component Bose mixture with dipole-dipole interaction. For such a system the effective hyd…
Dynamics of expansion of the Universe in the models with non-minimally coupled dark energy
R. Neomenko, B. Novosyadlyj
We consider the dark energy model with barotropic equation of state, which interacts with dark matter through gravitation and another force, causing the energy-momentum exchange be…
