Bogolon-mediated light absorption in atomic condensates of different dimensionality

open access: yesScientific Reports, 2023
In the case of structureless bosons, cooled down to low temperatures, the absorption of electromagnetic waves by their Bose-Einstein condensate is usually forbidden due to the momentum and energy conservation laws: the phase velocity of the collective ...

Composite structure of vortices in two-component Bose-Einstein condensate

open access: yesOpen Physics, 2015
In contrast to one-component Bose-Einstein condensate case, the vortices in two-component condensate can have various complicated structures. The vortices in a space-homogeneous Bose-Einstein condensate have been studied in this paper.

Parametric Excitation of a Bose-Einstein Condensate: From Faraday Waves to Granulation [PDF]

open access: yesPhysical Review X, 2017
A shaken Bose-Einstein condensate generates not only repeatable wave patterns known as Faraday waves, but also unexpected grains that may arise from shaking-induced quantum correlations.

Theory of BCS-like bogolon-mediated superconductivity in transition metal dichalcogenides

open access: yesNew Journal of Physics, 2021
We report on a novel mechanism of BCS-like superconductivity, mediated by a pair of Bogoliubov quasiparticles (bogolons). It takes place in hybrid systems consisting of a two-dimensional electron gas in a transition metal dichalcogenide monolayer in the ...

How creating one additional well can generate Bose-Einstein condensation

open access: yesCommunications 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.

Interaction of a Bose–Einstein condensate and a superconductor via eddy currents

open access: yesNew 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 ...

Characterisation of the dynamical quantum state of a zero temperature Bose-Einstein condensate [PDF]

open access: yes, 2002
We describe the quantum state of a Bose-Einstein condensate at zero temperature. By evaluating the Q-function we show that the ground state of Bose-Einstein condensate under the Hartree approximation is squeezed.

Exact analysis and elastic interaction of multi-soliton for a two-dimensional Gross-Pitaevskii equation in the Bose-Einstein condensation

open access: yesJournal 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

open access: yesNature 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
