Quantum dark solitons in the 1D Bose gas: From single to double dark-solitons
Kayo Kinjo, Eriko Kaminishi, Takashi Mori +3
We study quantum double dark-solitons by constructing corresponding quantum states in the Lieb-Liniger model for the one-dimensional Bose gas. Here we expect that the Gross-Pitaevs…
Recurrence times of the Lieb-Liniger model in the weak and strong coupling regimes
Eriko Kaminishi, Takashi Mori
Quantum systems exhibit recurrence phenomena after equilibration, but it is a difficult task to evaluate the recurrence time of a quantum system because it drastically increases as…
Construction of quantum dark soliton in one-dimensional Bose gas
Eriko Kaminishi, Takashi Mori, Seiji Miyashita
Dark soliton solutions in the one-dimensional classical nonlinear Schrödinger equation has been considered to be related to the yrast states corresponding to the type-II excitation…
Entanglement prethermalization: Locally thermal but non-locally non-thermal states in a one-dimensional Bose gas
Eriko Kaminishi, Takashi Mori, Tatsuhiko N. Ikeda +1
A well-isolated system often shows relaxation to a quasi-stationary state before reaching thermal equilibrium. Such a prethermalization has attracted considerable interest recently…
