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…
The anti-glitching gamma-ray pulsar PSR J1522-5735
A. G. Panin, E. V. Sokolova
Context. A small number of pulsar glitches have been identified as anti-glitches or spin-down glitches, where the overall contribution to the pulsar's rotation frequency is negativ…
Scattering of linear waves on a soliton
A. S. Dmitriev, E. A. Dmitrieva, A. G. Panin
We have shown that the wave scattering by a soliton occurs in a peculiar way. The nonlinear interaction leads to the generation of waves with frequencies that are multiples of the…
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…
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…
Instability of rotating Bose stars
A. S. Dmitriev, D. G. Levkov, A. G. Panin +2
Light bosonic (axion-like) dark matter may form Bose stars - clumps of nonrelativistic Bose-Einstein condensate supported by self-gravity. We study rotating Bose stars composed of…
