Vortex State of Ultralight Dark Matter and the Fornax Timing Problem
V. Gorkavenko, O. Barabash, T. Gorkavenko +4
We investigate the impact of the vortex state of the ultralight dark matter (ULDM) on the dynamical friction acting on moving globular clusters. Comparing this force with that for…
Analytic calculation of dynamical friction for Plummer sphere in ultralight dark matter
O. V. Barabash, T. V. Gorkavenko, V. M. Gorkavenko +4
The dynamical friction force acting on a spatially extended probe (globular clusters and dwarf galaxies) moving in the environment of ultralight bosonic dark matter in the state of…
Hydrodynamical approach to chirality production during axion inflation
E. V. Gorbar, A. I. Momot, O. O. Prikhodko +1
We study chirality production in the pseudoscalar inflation model of magnetogenesis taking into account the Schwinger effect and particle collisions in plasma in the relaxation tim…
Magnetogenesis in non-local models during inflation
E. V. Gorbar, T. V. Gorkavenko, V. M. Gorkavenko +1
The generation of magnetic fields during inflation in an electromagnetic model with a non-local form factor in Maxwell`s action is studied. The equations of motion for the electrom…
Unruh entropy of Schwarzschild black hole
M. Teslyk, L. Bravina, E. Zabrodin +1
The entropy produced by the Unruh radiation is estimated and compared to the entropy of a Schwarzschild black hole. We simulate a spherical system of mass by set of Unruh hor…
Generation of an electromagnetic field nonminimally coupled to gravity during Higgs inflation
O. O. Sobol, E. V. Gorbar, O. M. Teslyk +1
In the framework of Higgs inflation, we consider the electromagnetic field nonminimally coupled to gravity via the parity-preserving and parity-violating $\propto…
Fermi arcs and DC transport in nanowires of Dirac and Weyl semimetals
P. O. Sukhachov, M. V. Rakov, O. M. Teslyk +1
The transport properties and electron states in cylinder nanowires of Dirac and Weyl semimetals are studied paying special attention to the structure and properties of the surface…
Unruh effect and entropy of Schwarzschild black hole
M. v. Teslyk, O. M. Teslyk, L. V. Zadorozhna
We consider Unruh effect as an origin for Schwarzschild black hole entropy thus implying unitarian evolution of gravity. We simulate the black hole by set of Unruh horizons and est…
Particle thermalization entropy and Unruh effect
Maksym Teslyk, Olena Teslyk
We propose the method for estimation of entropy generated during the string breaking in high energy collisions. The approach is highly based on the ideas proposed by Kharzeev D et…
Scalar field entanglement entropy for small Schwarzschild black hole
Maksym Teslyk, Olena Teslyk
We consider scalar field entanglement entropy generated with black hole of (sub)planck mass scale thus implying the unitary evolution of gravity. The dependence on the dimension of…
