Molecular Tagging Velocimetry in Superfluid Helium-4: Progress, Issues, and Future Development
Wei Guo
Helium-4 in the superfluid phase (He II) is a two-fluid system that exhibits fascinating quantum hydrodynamics with important scientific and engineering applications. However, the…
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…
Diffusive versus displacive contact plasticity of nanoscale asperities: Temperature- and velocity-dependent strongest size
Wei Guo, Zhao Wang, Ju Li
We predict a strongest size for the contact strength when asperity radii of curvature decrease below ten nanometers. The reason for such strongest size is found to be correlated wi…
