Spin turbulence in spinor Bose-Einstein condensates
Makoto Tsubota, Kazuya Fujimoto
We summarize the recent theoretical and numerical works on spin turbulence (ST) in spin-1 spinor Bose-Einstein condensates. When the system is excited from the ground state, it goe…
Expansion of a Bose-Einstein Condensate with Vortices
Ryo Tsuchitani, Makoto Tsubota
The expansion of Bose-Einstein condensates (BECs) is numerically studied. Usually, the aspect ratio of a condensate is inverted due to the anisotropy of the uncertainty principle.…
Statistics of vortex loops emitted from quantum turbulence driven by an oscillating sphere
Ai Nakatsuji, Makoto Tsubota, Hideo Yano
We perform numerical simulation of quantum turbulence at zero temperature generated by an oscillating sphere. In this simulation, we injected vortices on the sphere to generate tur…
Counter-rotating vortices in miscible two-component Bose-Einstein condensates
Shungo Ishino, Makoto Tsubota, Hiromitsu Takeuchi
Counter-rotating vortices in miscible two-component Bose-Einstein condensates, in which superflows counter-rotate between the two components around the overlapped vortex cores, are…
Spin turbulence with small spin magnitude in spin-1 spinor Bose-Einstein condensates
Kazuya Fujimoto, Makota Tsubota
We theoretically and numerically study spin turbulence (ST) with small spin magnitude in spin-1 spinor Bose-Einstein condensates by using the spin-1 spinor Gross-Pitaevskii (GP)equ…
Instability crossover of helical shear flow in segregated Bose-Einstein condensates
Shinsuke Hayashi, Makoto Tsubota, Hiromitsu Takeuchi
We theoretically study the instability of helical shear flows, in which one fluid component flows along the vortex core of the other, in phase-separated two-component Bose-Einstein…
