Coexistence of photonic and atomic Bose-Einstein condensates in ideal atomic gases

Condensed Matter Physics, 2015
We have studied conditions of photon Bose-Einstein condensate formation that is in thermodynamic equilibrium with ideal gas of two-level Bose atoms below the degeneracy temperature.

Bethe states for the two-site Bose–Hubbard model: A binomial approach

Physics Letters B, 2015
We calculate explicitly the Bethe vectors states by the algebraic Bethe ansatz method with the gl(2)-invariant R-matrix for the two-site Bose–Hubbard model.

A century of the Bose–Einstein condensation concept and half a century of the JINR experiments for observation of condensate in superfluid 4He (He II)

Natural Science Review
This short review is devoted to the celebration of two major events in quantum physics. The first one is the birth of the concept of Bose–Einstein condensation (1925) and the second is the experimental proof that it does exist and appears in liquid 4He ...

Observation of dynamic atom-atom correlation in liquid helium in real space

Nature Communications, 2017
Liquid helium can be treated as an ideal gas or a condensed liquid and displays intriguing features like Bose–Einstein condensation. Here the authors show that roton excitation reveals information on real space dynamic atom-atom correlations in ...

Condensation of excitons in Cu2O at ultracold temperatures: experiment and theory

New Journal of Physics, 2012
We present experiments on the luminescence of excitons confined in a potential trap at milli-Kelvin bath temperatures under continuous-wave (cw) excitation.
