Effect of Rotation on Elastic Moduli of Solid He
Tomoya Tsuiki, Daisuke Takahashi, Satoshi Murakawa +3
We report measurements of elastic moduli of hcp solid He down to 15 mK when the samples are rotated unidirectionally. Recent investigations have revealed that the elastic behav…
Superfluid-like TO Responses in Rotating Solid Helium
Jaewon Choi, Tomoya Tsuiki, Daisuke Takahashi +4
The irrotational nature of superfluid helium was discovered through its decoupling from the container under rotation. Similarly, the resonant period drop of a torsional oscillator…
Nambu-Goldstone Modes Propagating along Topological Defects: Kelvin and Ripple Modes from Small to Large Systems
Daisuke A. Takahashi, Michikazu Kobayashi, Muneto Nitta
Nambu-Goldstone modes associated with (topological) defects such as vortices and domain walls in (super)fluids are known to possess quadratic/non-integer dispersion relations in fi…
Absence of Anomalous Tunneling of Bogoliubov Excitations for Arbitrary Potential Barrier under the Critical Condensate Current
Daisuke Takahashi, Yusuke Kato
We derive the exact solution of low energy limit of Bogoliubov equations for excitations of Bose-Einstein condensate in the presence of arbitrary potential barrier and maximum curr…
