A novel method to create a vortex in a Bose-Einstein condensate
Shin-ichiro Ogawa, Mikko Mottonen, Mikio Nakahara +2
It has been shown that a vortex in a BEC with spin degrees of freedom can be created by manipulating with external magnetic fields. In the previous work, an optical plug along the…
Reconnection and acoustic emission of quantized vortices in superfluid by the numerical analysis of the Gross-Pitaevskii equation
S. Ogawa, M. Tsubota, Y. Hattori
We study numerically the reconnection of quantized vortices and the concurrent acoustic emission by the analysis of the Gross-Pitaevskii equation. Two quantized vortices reconnect…
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…
