Creation of persistent current and vortex in a Bose-Einstein condensate of alkali-metal atoms
Tomoya Isoshima, Mikio Nakahara, Tetsuo Ohmi +1
It is shown theoretically that a persistent current can be continuously created in a Bose-Einstein condensate (BEC) of alkali atoms confined in a multiply connected region by makin…
A simple method to create a vortex in Bose-Einstein condensate of alkali atoms
Mikio Nakahara, Tomoya Isoshima, Kazushige Machida +2
Bose-Einstein condensation in alkali atoms has materialized quite an interesting system, namely a condensate with a spin degree of freedom. In analogy with the A-phase of the super…
Spin domain formation in spinor Bose-Einstein condensation
Tomoya Isoshima, Kazushige Machida, Tetsuo Ohmi
The spatial structure of the spinor Bose-Einstein condensates with the spin degrees of freedom is analyzed based on the generalized Gross-Pitaevskii equation (GP) in the light of t…
Instability of Non-vortex State toward a Quantized Vortex in Bose-Einstein Condensate under External Rotation
Tomoya Isoshima, Kazushige Machida
The instability condition of the non-vortex state toward vortex formation is exa mined within the Bogoliubov theory when a Bose-Einstein condensate is under exte rnally forced rota…
