Ground, Symmetric and Central Vortex States in Rotating Bose-Einstein Condensates

Abstract: Abstract. We study ground, symmetric and central vortex states, as well as their energy and chemical potential diagrams, in rotating Bose-Einstein condensates (BEC) analytically and numerically. We start from the three-dimensional (3D) Gross-Pitaevskii equation (GPE) with an angular momentum rotation term, scale it to obtain a four-parameter model, reduce it to a 2D GPE in the limiting regime of strong anisotropic confinement and present its semiclassical scaling and geometrical optics. We discuss the existenc… Show more

“…In addition, when the computational domain is a disk in 2D, and resp., a cylinder in 3D, the SIFD discretization can be extremely efficient in practical computation by using polar coordinates in 2D, and resp., cylindrical coordinates in 3D, together with fast direct Poisson solver. A similar idea to this method has been used in simulating quantized vortex dynamics in rotating BEC [6,9,12].…”
