Dynamical Transition of Quantum Vortex-Pair Annihilation in a Bose-Einstein Condensate
Toshiaki Kanai, Chuanwei Zhang
Understanding the elementary mechanism for the dissipation of vortex energy in quantum liquids is one central issue in quantum hydrodynamics, such as quantum turbulence in systems…
Imaging the decay of quantized vortex rings to decipher quantum dissipation
Yuan Tang, Wei Guo, Hiromichi Kobayashi +3
Like many quantum fluids, superfluid helium-4 (He II) can be considered as a mixture of two miscible fluid components: an inviscid superfluid and a viscous normal fluid consisting…
The true mechanism of spontaneous order from turbulence in two-dimensional superfluid manifolds
Toshiaki Kanai, Wei Guo
In a two-dimensional (2D) turbulent fluid containing point-like vortices, Lars Onsager predicted that adding energy to the fluid can lead to the formation of persistent clusters of…
Torquing the Condensate: Angular Momentum Transport in Bose-Einstein Condensates by Solitonic "Corkscrew"
Toshiaki Kanai, Wei Guo, Makoto Tsubota +1
When rotating classical fluid drops merge together, angular momentum can be advected from one to another due to the viscous shear flow at the drop interface. It remains elusive wha…
Emergence of spiral dark solitons in the merging of rotating Bose-Einstein condensates
Toshiaki Kanai, Wei Guo, Makoto Tsubota
Merging of isolated Bose-Einstein condensates (BECs) is an important topic due to its relevance to matter-wave interferometry and the Kibble-Zurek mechanism. Many past research foc…
Rotation and Angular Momentum Transfer in Bose-Einstein Condensates Induced by Spiral Dark Solitons
Toshiaki Kanai, Wei Guo, Makoto Tsubota
It is a common view that rotational motion in a superfluid can exist only in the presence of quantized vortices. However, in our numerical studies on the merging of two concentric…
