Turbulence in Boundary Flow of Superfluid He Triggered by Free Vortex Rings
R. Goto, S. Fujiyama, H. Yano +6
The transition to turbulence in the boundary flow of superfluid He is investigated using a vortex--free vibrating wire. At high wire vibration velocities, we found that stable…
Zel'dovich-Starobinsky Effect in Atomic Bose-Einstein Condensates: Analogy to Kerr Black Hole
Hiromitsu Takeuchi, Makoto Tsubota, Grigory E. Volovik
We consider circular motion of a heavy object in an atomic Bose-Einstein condensate (BEC) at . Even if the linear velocity of the object is smaller than the Landau crit…
Quantized vortices in atomic Bose-Einstein condensates
Kenichi Kasamatsu, Makoto Tsubota
In this review, we give an overview of the experimental and theoretical advances in the physics of quantized vortices in dilute atomic-gas Bose--Einstein condensates in a trapping…
Terahertz conductivity of localized photoinduced carriers in Mott insulator YTiO at low excitation density, contrasted with metallic nature in band semiconductor Si
J. Kitagawa, Y. Kadoya, M. Tsubota +2
We performed optical-pump terahertz-probe measurements of a Mott insulator YTiO and a band semiconductor Si using a laser diode (1.47 eV) and a femtosecond pulse laser (1.55…
Quantum Turbulence in a Trapped Bose-Einstein Condensate
Michikazu Kobayashi, Makoto Tsubota
We study quantum turbulence in trapped Bose-Einstein condensates by numerically solving the Gross-Pitaevskii equation. Combining rotations around two axes, we successfully induce q…
