Vortex-lattice formation in a spin-orbit coupled rotating spin-1 condensate
(2020-11-06)
We study the vortex-lattice formation in a rotating Rashba spin-orbit (SO) coupled quasi-two-dimensional (quasi-2D) hyper-fine spin-1 spinor Bose-Einstein condensate (BEC) in the x-y plane using a numerical solution of the ...
Phase-separated vortex-lattice in a rotating binary Bose–Einstein condensate
(2019-06-15)
We study circularly-symmetric phase separation of vortex lattices in a rapidly rotating harmonically-trapped quasi-two-dimensional binary Bose–Einstein condensate (BEC) by introducing a weak quartic trap in one of the ...
Phase-separated symmetry-breaking vortex-lattice in a binary Bose-Einstein condensate
(2020-01-01)
We study spontaneous-symmetry-breaking circularly-asymmetric phase separation of vortex lattices in a rapidly rotating harmonically-trapped quasi-two-dimensional (quasi-2D) binary Bose-Einstein condensate (BEC) with repulsive ...
Change of the vortex lattice symmetry in the vicinity of the macro-to-mesoscopic threshold
(Elsevier B.V., 2012-09-01)
In the present work we study the influence of the surface on the vortex structure as a function of the sample size for different temperatures. It is shown that a crossover between a hexagonal lattice, which is characteristic ...

The holographic vortex lattice using the circular cell method.
We investigate vortex lattice solutions in a holographic superconductor model in asymptotically AdS4 spacetime which includes the gravitational backreaction of the vortex. The circular cell approximation, which is known ...
Vortex pseudomomentum and dissipation in a superfluid vortex lattice
(IOP Publishing, 2008-07)
We propose an alternative approach to the dissipative vortex dynamics occurring in a superfluid vortex lattice at finite temperatures. Focusing upon the pseudomomentum of a vortex and its surrounding quasiparticles, we ...
Vortex-lattice in a uniform Bose-Einstein condensate in a box trap
(2019-01-01)
We study numerically the vortex-lattice formation in a rapidly rotating uniform quasi-twodimensional Bose-Einstein condensate (BEC) in a box trap. We consider two types of boxes: square and circle. In a square-shaped 2D ...
Critical currents and melting temperature of a two-dimensional vortex lattice with periodic pinning
(2013-06-01)
The critical current and melting temperature of a vortex system are analyzed. Calculations are made for a two-dimensional film at finite temperature with two kinds of periodic pinning: hexagonal and Kagomé. A transport ...
