Corotation of two quantized vortices coupled with collective modes in self-gravitating Bose-Einstein condensates
Kenta Asakawa, Makoto Tsubota
We numerically examine the corotation of two parallel quantized vortices in a self-gravitating Bose-Einstein condensate (BEC) employing the Gross-Pitaevskii-Poisson equations. The…
Influence of different mutual friction models on two-way coupled quantized vortices and normal fluid in superfluid He
Hiromichi Kobayashi, Satoshi Yui, Makoto Tsubota
We study the influence of two mutual friction models on quantized vortices and normal fluid using two-way coupled simulations of superfluid He. The normal fluid is affected by…
Emergence of isotropy in rotating turbulence of Bose-Einstein condensates
Yuto Sano, Makoto Tsubota
We present a study on the development of rotating turbulence in Bose-Einstein condensates with a dissipative Gross-Pitaevskii model. Turbulence is generated by driving the lattice…
Dynamics of pinned quantized vortices in superfluid He in a microelectromechanical oscillator
Tomo Nakagawa, Makoto Tsubota, Keegan Gunther +1
We numerically studied the vortex dynamics at zero temperature in superfluid He confined between two parallel rough solid boundaries, one of which oscillates in a shear mode. T…
Collective Excitations of Self-Gravitating Bose-Einstein Condensates: Breathing Mode and Appearance of Anisotropy under Self-Gravity
Kenta Asakawa, Hideki Ishihara, Makoto Tsubota
We investigate the collective mode of a self-gravitating Bose-Einstein condensate (BEC) described by the Gross-Pitaevskii-Poisson (GPP) equations. The self-gravitating BEC has garn…
Universal defect density scaling in an oscillating dynamic phase transition
Wei-can Yang, Makoto Tsubota, Adolfo del Campo +1
Universal scaling laws govern the density of topological defects generated while crossing an equilibrium continuous phase transition. The Kibble-Zurek mechanism (KZM) predicts the…
