Electron Lateral Trapping Induced by Non-Uniform Thickness in Solid Neon Layers
Toshiaki Kanai, Chuanwei Zhang
Recent experimental advances highlight electron charge qubits floating above solid neon as an emerging promising platform for quantum computing, but the physical origin of single-e…
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…
Single-electron qubits based on quantum ring states on solid neon surface
Toshiaki Kanai, Dafei Jin, Wei Guo
Single electrons trapped on solid neon surfaces (eNe) have recently emerged as a promising platform for charge qubits. Experimental results have revealed their exceptionally long c…
Boiling peak heat flux for steady inhomogeneous heat transfer in superfluid He
Sosuke Inui, Mikai Hulse, Toshiaki Kanai +1
Superfluid helium-4 (He II) is a widely adopted coolant in scientific and engineering applications owing to its exceptional heat transfer capabilities. However, boiling can spontan…
Vinen's latest thoughts on the "bump'' puzzle in decaying He II counterflow turbulence
Wei Guo, Toshiaki Kanai
The pioneering work of William F. Vinen (also known as Joe Vinen) on thermal counterflow turbulence in superfluid helium-4 largely inaugurated the research on quantum turbulence. B…
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…
Stereoscopic molecular tagging for superconducting accelerator-cavity quench spot detection
Shiran Bao, Toshiaki Kanai, Yang Zhang +2
Superconducting radio-frequency (SRF) cavities cooled by superfluid helium-4 (He II) are building blocks of many modern particle accelerators due to their high quality factor. Howe…
An exploration of Homogeneous Isotropic Turbulence in He II Using Particle Tracking Velocimetry
Yuan Tang, Shiran Bao, Toshiaki Kanai +1
Despite being a quantum two-fluid system, superfluid helium-4 (He II) is observed to behave similarly to classical fluids when a flow is generated by mechanical forcing. This simil…
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…
