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.

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

Composite structure of vortices in two-component Bose-Einstein condensate
Open 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
New 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
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 ...

Journal of Bangladesh Academy of Sciences, 1970 The work represents and investigates the stationary solutions of the one-dimensional Non-linear Schrödinger Equation (NLSE), for attractive non-linearity, in the Bose-Einstein condensates (BEC) under the box boundary condition and calculates the characteristics of internal modes of bright solitons (eigen modes of small perturbation of the condensate ...

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.

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.

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
