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…
Faraday Waves in Bose-Einstein Condensates -- The Excitation by the Modulation of the Interaction and the Potential
Nobuyuki Shukuno, Yuto Sano, Makoto Tsubota
We numerically study the dynamics of Faraday waves for Bose-Einstein condensates(BECs) trapped by anisotropic potentials using the three-dimensional Gross-Pitaevskii equation. In p…
Studies on quantum turbulence with Vinen
Makoto Tsubota
In my research career in the field of quantum turbulence, I have been encouraged by Vinen. In this article, I review my works motivated by him and my joint collaborations with him.…
