Unconventional superfluidity and quantum geometry of topological bosons
Ilya Lukin, Andrii Sotnikov, Alexander Kruchkov
We investigate superfluidity of bosons in gapped topological bands and discover a new phase that has no counterparts in the previous literature. This phase is characterized by a hi…
One-dimensional Bose-Einstein condensation of photons in a microtube
Alex J. Kruchkov
This paper introduces a quasiequilibrium one-dimensional Bose-Einstein condensation of photons trapped in a microtube. Light modes with a cut-off frequency (a photon's "mass") inte…
Radiation spectrum of systems with condensed light
Alex Kruchkov
Experimental observation of Bose-Einstein condensation (BEC) of photons inside a microcavity induced an extensive study of the phenomenon. Beyond the purely theoretical interest, t…
Bose-Einstein condensation of light in a cavity
Alex Kruchkov
The paper considers Bose-Einstein condensation (BEC) of light in a cavity with medium. In the framework of two-level model we show the effect of gaseous medium on the critical temp…
Bose-Einstein condensation of photons in an ideal atomic gas
Alex Kruchkov, Yurii Slyusarenko
We study peculiarities of Bose-Einstein condensation of photons that are in thermodynamic equilibrium with atoms of noninteracting gases. General equations of the thermodynamic equ…
Mechanism of collisionless sound damping in dilute Bose gas with condensate
Yu. Slyusarenko, A. Kruchkov
We develop a microscopic theory of sound damping due to Landau mechanism in dilute gas with Bose condensate. It is based on the coupled evolution equations of the parameters descri…
