Interaction of a Bose–Einstein condensate and a superconductor via eddy currents
New Journal of Physics, 2013 We study center-of-mass oscillations of a dipolar Bose–Einstein condensate in the vicinity of a superconducting surface. We show that the magnetic field of the magnetic dipoles induces eddy currents in the superconductor, which act back on the Bose ...

How creating one additional well can generate Bose-Einstein condensation
Communications Physics, 2021 Bose-Einstein condensation was theoretically predicted almost 150 years ago but experimentally realized this century, reviving the interest in this striking quantum phenomenon.

Journal of Advanced Research, 2022 Introduction: The Gross-Pitaevskii equation is a class of the nonlinear Schrödinger equation, whose exact solution, especially soliton solution, is proposed for understanding and studying Bose-Einstein condensate and some nonlinear phenomena occurring in

Manipulating polariton condensates by Rashba-Dresselhaus coupling at room temperature
Nature Communications, 2022 Engineered spin-orbit coupling can induce novel quantum phases in a Bose-Einstein condensate, however such demonstrations have been limited to cold atom systems. Here the authors realize a exciton-polarion condensate with tunable spin-orbit coupling in a

Universality of an impurity in a Bose-Einstein condensate [PDF]
, 2017 Universality is a powerful concept in physics, allowing one to construct physical descriptions of systems that are independent of the precise microscopic details or energy scales.

Excitations in a nonequilibrium Bose-Einstein condensate of exciton polaritons. [PDF]
Physical Review Letters, 2007 We develop a mean-field theory of the dynamics of a nonequilibrium Bose-Einstein condensate of exciton polaritons in a semiconductor microcavity. The spectrum of elementary excitations around the stationary state is analytically studied by means of a ...

Chemical potential of quasi-equilibrium magnon gas driven by pure spin current
Nature Communications, 2017 Spin current-induced quasi-equilibrium state of magnon gas described by the Bose–Einstein statistics has been previously theoretically predicted.

Observation of Bose-Einstein condensates of excitons in a bulk semiconductor
Nature Communications, 2022 Bose-Einstein condensate of excitons is expected in photo-excited bulk semiconductors, but a direct experimental evidence has been lacking. Here the authors report the observation of a condensate of 1s paraexcitons in Cu2O using real-space mid-infrared ...

Can dark matter be a Bose–Einstein condensate? [PDF]
, 2007 We consider the possibility that the dark matter which is required to explain the dynamics of the neutral hydrogen clouds at large distances from the galactic centre could be in the form of a Bose–Einstein condensate.

Slowly rotating Bose Einstein condensate galactic dark matter halos, and their rotation curves
European Physical Journal C: Particles and Fields, 2018 If dark matter is composed of massive bosons, a Bose–Einstein condensation process must have occurred during the cosmological evolution. Therefore galactic dark matter may be in a form of a condensate, characterized by a strong self-interaction.
