Mutual Friction in Dissipative Gross-Pitaevskii Thermal Counterflow Turbulence
Kyo Yoshida, Hideaki Miura, Yoshiyuki Tsuji
We report numerical simulations of the dissipative Gross-Pitaevskii equation for a bulk region of thermal-counterflow turbulence. Quasistationary states are obtained over a range o…

Numerical search for states with constant enstrophy flux over finite time intervals in two-dimensional turbulence
Kyo Yoshida
An ensemble model of turbulence based on states with constant flux in wavenumber space was proposed in [K. Yoshida, Phys. Rev. E, 106, 045106 (2022)]. The justification of this ens…

Boltzmann entropy for quantum field systems
Kyo Yoshida
A way to construct Boltzmann entropy, i.e., the entropy as a function of a microscopic pure state, for quantum field systems is proposed. Operators that shift the field in wavevect…
