Skin phase transition of a skyrmion in a ferromagnetic superfluid
Wooyoung Yun, Se Kwon Kim, Hiromitsu Takeuchi
Compared with a scalar Bose-Einstein condensate (BEC), a spinor BEC supports richer phenomena because of its internal spin degrees of freedom, including topological solitons such a…
Anomalous minimization for critical velocity of superflow along a step potential
Akihiro Kanjo, Hiromitsu Takeuchi
To reveal a microscopic mechanism for the anomalous minimization and dependence of the superfluid critical velocity on a moving obstacle potential in a atomic Bose-Einstein condens…
Effect of Population Imbalance on Vortex Mass in Superfluid Fermi Gases
Lucas Levrouw, Hiromitsu Takeuchi, Jacques Tempere
One of the fundamental parameters associated with quantized vortices in superfluids is the vortex mass, which is the inertia of a vortex. As of yet, this mass has not been observed…
Dynamic scaling of vorticity in phase-separating superfluid mixtures
Ryuta Ito, Hiromitsu Takeuchi
Recently, it has been experimentally confirmed that non-equilibrium dynamics of phase separation in strongly ferromagnetic Bose-Einstein condensates of Li atoms obey the dynami…
Proper Orthogonal Decomposition of a Superfluid Turbulent Wake
Sota Yoneda, Hiromitsu Takeuchi
Superfluid turbulent wakes behind a square prism are studied theoretically and numerically by proper orthogonal decomposition (POD). POD is a data science approach that can efficie…
Vortex Mass in Superfluid Fermi Gases along the BEC-BCS Crossover
Lucas Levrouw, Hiromitsu Takeuchi, Jacques Tempere
Vortex mass is a key concept in the study of superfluid dynamics, referring to the inertia of vortices in a superfluid, which affects their motion and behavior. Despite being an im…
Universal description of massive point vortices and verification methods of vortex inertia in superfluids
Akihiro Kanjo, Hiromitsu Takeuchi
Vortex mass, which is the inertia of a quantum vortex, has never been observed in superfluids and is a long-standing problem in low temperature physics. The impact of the mass is c…
Stable singular fractional skyrmion spin texture from the quantum Kelvin-Helmholtz instability
SeungJung Huh, Wooyoung Yun, Gabin Yun +7
Topology profoundly influences diverse fields of science, providing a powerful framework for classifying phases of matter and predicting nontrivial excitations, such as solitons, v…
