Problem with classical stability of U(1) gauged Q-balls
A. G. Panin, M. N. Smolyakov
In this paper, we present a detailed study of the problem of classical stability of U(1) gauged Q-balls. In particular, we show that the standard methods that are suitable for esta…
Relativistic axions from collapsing Bose stars
D. G. Levkov, A. G. Panin, I. I. Tkachev
The substructures of light bosonic (axion-like) dark matter may condense into compact Bose stars. We study collapses of the critical-mass stars caused by attractive self-interactio…
Strong-coupling scale and frame-dependence of the initial conditions for chaotic inflation in models with modified (coupling to) gravity
Dmitry Gorbunov, Alexander Panin
A classical evolution in chaotic inflationary models starts at high energy densities with semi-classical initial conditions presumably consistent with universal quantum nature of a…
Are - and Higgs-inflations really unlikely?
D. S. Gorbunov, A. G. Panin
We address the question of unlikeness of - and Higgs inflations exhibiting exponentially flat potentials and hence apparently violating the inherent in a chaotic inflation ini…
Scalaron the mighty: producing dark matter and baryon asymmetry at reheating
D. S. Gorbunov, A. G. Panin
In R^2-inflation scalaron slow roll is responsible for the inflationary stage, while its oscillations reheat the Universe. We find that the same scalaron decays induced by gravity…
