Thermal false vacuum decay near black holes is aspherical
D. S. Gorbunov, D. G. Levkov, V. E. Maslov
We study decay of a scalar field false vacuum near a (3+1)-dimensional Schwarzschild black hole equilibrated at Hawking temperature with the environment. Our scalar field model has…
False vacuum decay around black holes: calculation from first principles in the (3+1)-dimensional case
Ratmir Gazizov, Dmitry Gorbunov, Dmitry Levkov
In spacetime dimensions, we numerically calculate the suppression exponent of the false vacuum decay probability in the presence of a thermal bath and a black hole.
Self-similar kinetics for gravitational Bose-Einstein condensation
A. S. Dmitriev, D. G. Levkov, A. G. Panin +1
We study an overpopulated gas of gravitationally interacting bosons surrounding a droplet of Bose-Einstein condensate - Bose star. We argue that kinetic evolution of this gas appro…
Numerical study of multiparticle production in theory
S. Demidov, B. Farkhtdinov, D. Levkov
We study multiparticle production in the unbroken -dimensional theory using the semiclassical method of singular solutions. We show that the probabilities of these pr…
Analytic description of monodromy oscillons
D. G. Levkov, V. E. Maslov
We develop precise analytic description of oscillons - long-lived quasiperiodic field lumps - in scalar field theories with nearly quadratic potentials, e.g. the monodromy potentia…
Self-similar growth of Bose stars
A. S. Dmitriev, D. G. Levkov, A. G. Panin +1
We analytically solve the problem of Bose star growth in the bath of gravitationally interacting particles. We find that after nucleation of this object the bath is described by a…
