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.
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…
An Effective Field Theory for Large Oscillons
D. G. Levkov, V. E. Maslov, E. Ya. Nugaev +1
We consider oscillons - localized, quasiperiodic, and extremely long-living classical solutions in models with real scalar fields. We develop their effective description in the lim…
Semiclassical S-matrix and black hole entropy in dilaton gravity
Maxim Fitkevich, Dmitry Levkov, Sergey Sibiryakov
We use complex semiclassical method to compute scattering amplitudes of a point particle in dilaton gravity with a boundary. This model has nonzero minimal black hole mass …
Dilaton gravity with a boundary: from unitarity to black hole evaporation
Maxim Fitkevich, Dmitry Levkov, Yegor Zenkevich
We point out that two-dimensional Russo-Susskind-Thorlacius (RST) model for evaporating black holes is locally equivalent - at the full quantum level - to flat-space Jackiw-Teitelb…
Chaotic solitons in driven sine-Gordon model
D. G. Levkov, V. E. Maslov, E. Ya. Nugaev
Profiles of static solitons in one-dimensional scalar field theory satisfy the same equations as trajectories of a fictitious particle in multidimensional mechanics. We argue that…
