Bose-Einstein Condensation of Long-Lifetime Polaritons in Thermal Equilibrium [PDF]
, 2016 Exciton-polaritons in semiconductor microcavities have been used to demonstrate quantum effects such as Bose-Einstein condensation, superfluity, and quantized vortices.

Nonextensive Bose–Einstein condensation model [PDF]
Journal of Mathematical Physics, 1999 The imperfect Boson gas supplemented with a gentle repulsive interaction is completely solved. In particular, it is proved that it has nonextensive Bose–Einstein condensation, i.e., there is condensation without macroscopic occupation of the ground (k=0) state level.

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.

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.

Coherence and Optical Emission from Bilayer Exciton Condensates [PDF]
, 2010 Experiments aimed at demonstrating Bose-Einstein condensation of excitons in two types of experiments with bilayer structures (coupled quantum wells) are reviewed, with an emphasis on the basic effects. Bose-Einstein condensation implies the existence of

On the occurrence and detectability of Bose-Einstein condensation in helium white dwarfs [PDF]
, 2011 It has been recently proposed that helium white dwarfs may provide promising conditions for the occurrence of the Bose-Einstein condensation. The argument supporting this expectation is that in some conditions attained in the core of these objects, the ...

Bose-Einstein Condensation of Pions in High Multiplicity Events [PDF]
, 2006 We present microcanonical ensemble calculations of particle number fluctuations in the ideal pion gas approaching Bose-Einstein condensation. In the samples of events with a fixed number of all pions, $N_{\pi}$, one may observe a prominent signal.

Spin waves in a Bose Ferromagnet
, 2004 It is shown that the ferromagnetic transition takes place always above Bose-Einstein condensation in ferromagnetically coupled spinor Bose gases. We describe the Bose ferromagnet within Ginzburg-Landau theory by a "two-fluid" model below Bose-Einstein ...

Is a Trapped One-Dimensional Bose Gas a Luttinger Liquid?
, 1997 The low-energy fluctuations of a trapped, interacting quasi one-dimensional Bose gas are studied. Our considerations apply to experiments with highly anisotropic traps.

Schrodinger equation for the one particle density matrix of thermal systems: An alternative formulation of Bose-Einstein condensation [PDF]
, 2006 We formulate a linear Schrodinger equation with the temperature-dependent potential for the one-particle density matrix and obtain the condensation temperature of the Bose-Einstein condensate from a bound-state condition for the Schrodinger equation both
