Josephson effect in multicomponent Bose-Einstein condensates [PDF]

open access: yes, 2013
[cat]En aquesta Tesi s'estudia i es caracteritza el comportament dels condensats de Bose-Einstein en una junció bosònica de Josephson (BJJ), tot utilitzant dos formalismes teòrics diferents: l'aproximació de camp mig (amb l'equació de Gross-Pitaevskii) i

Imprinting a topological interface using Zeeman shifts in an atomic spinor Bose–Einstein condensate [PDF]

open access: yes, 2014
We propose to use spatial control of the Zeeman energy shifts in an ultracold atomic gas to engineer an interface between topologically distinct regions.

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.

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 ...

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 ...

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.

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

Observation of Bose-Einstein condensates of excitons in a bulk semiconductor

open access: yesNature 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 ...
