Theory of Bose-Einstein condensation in trapped gases [PDF]
, 1998 The phenomenon of Bose-Einstein condensation of dilute gases in traps is reviewed from a theoretical perspective. Mean-field theory provides a framework to understand the main features of the condensation and the role of interactions between particles ...

Quantum Geometry and Flat Band Bose-Einstein Condensation. [PDF]
Physical Review Letters, 2021 We study the properties of a weakly interacting Bose-Einstein condensate (BEC) in a flat band lattice system by using the multiband Bogoliubov theory and discover fundamental connections to the underlying quantum geometry.

Gravitational Bose-Einstein Condensation in the Kinetic Regime. [PDF]
Physical Review Letters, 2018 We study Bose-Einstein condensation and the formation of Bose stars in virialized dark matter halos and miniclusters by universal gravitational interactions. We prove that this phenomenon does occur and it is described by a kinetic equation.

Kinetics of Strongly Nonequilibrium Magnon Gas Leading to Bose-Einstein Condensation [PDF]
Журнал нано- та електронної фізики, 2017 Kinetic equations describing nonequilibrium magnon gas under the action of parametric pumping are considered with an account of kinetic instability processes. These processes strongly influence condition of magnon Bose-Einstein condensate formation.

Physics Letters B, 2023 Recent experimental efforts were made to explore the Bose-Einstein condensation in multi-α system using the heavy-ion collisions. This Letter provides an explanation why no signatures were observed and a guidance for future experiments. More precisely, a

New Journal of Physics, 2012 We theoretically study the loading of a two-species Bose-Einstein condensate to an optical lattice in a tightly-confined one-dimensional trap. Due to quantum fluctuations the relative inter and intra species phase coherence between the atoms and the on-site atom number fluctuations are reduced in the miscible regime.

Competition between Bose Einstein Condensation and spin dynamics [PDF]
, 2016 We study the impact of spin-exchange collisions on the dynamics of Bose-Einstein condensation, by rapidly cooling a chromium multi-component Bose gas.

Space-borne Bose–Einstein condensation for precision interferometry [PDF]
Nature, 2018 Owing to the low-gravity conditions in space, space-borne laboratories enable experiments with extended free-fall times. Because Bose–Einstein condensates have an extremely low expansion energy, space-borne atom interferometers based on Bose–Einstein ...

A Dicke Type Model for Equilibrium BEC Superradiance [PDF]
, 2004 We study the effect of electromagnetic radiation on the condensate of a Bose gas. In an earlier paper we considered the problem for two simple models showing the cooperative effect between Bose-Einstein condensation and superradiance.
