Supersonic optical tunnels for Bose–Einstein condensates

We propose a method for the stabilization of a stack of parallel vortex rings in a Bose–Einstein condensate. The method makes use of a ‘hollow’ laser beam containing an optical vortex. Using realistic experimental parameters we demonstrate numerically that our method can stabilize up to nine vortex rings. Furthermore we point out that the condensate flow through the tunnel formed by the core of...

Spinor Bose-Einstein condensates in optical traps

We have studied the equilibrium state of spinor condensates in an optical trap [1]. In contrast to magnetically trapped condensates, spinor condensates have the orientation of the spin as a degree of freedom, which can be described by a multi-component wavefunction (one for each magnetic sublevel). In an F=1 spinor condensate subject to spin relaxation, two mF=0 atoms can collide and produce a ...
