Dynamics of quantum double dark-solitons and an exact finite-size scaling of Bose-Einstein condensation
Kayo Kinjo, Jun Sato, Tetsuo Deguchi
We show several novel aspects in the exact non-equilibrium dynamics of quantum double dark-soliton states in the Lieb-Liniger model for the one-dimensional Bose gas with repulsive…
Multi-Quantum Dark Solitons in One-Dimensional Bose Gas
Yuki Ishiguro, Jun Sato, Katsuhiro Nishinari
Quantum and classical integrable systems share common mathematical structures, and the phenomena appearing in them are interrelated. Solitons, which universally appear in classical…
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…
Quantum states of dark solitons in the 1D Bose gas
Jun Sato, Rina Kanamoto, Eriko Kaminishi +1
We present a series of quantum states that are characterized by dark solitons of the nonlinear Schrödinger equation (i.e. the Gross-Pitaevskii equation) for the one-dimensional (1D…
Exact quantum dynamics of yrast states in the finite 1D Bose gas
Eriko Kaminishi, Jun Sato, Tetsuo Deguchi
We demonstrate that the quantum dynamics of yrast states in the one-dimensional (1D) Bose gas gives an illustrative example to equilibration of an isolated quantum many-body system…
Recurrence time in the quantum dynamics of the 1D Bose gas
Eriko Kaminishi, Jun Sato, Tetsuo Deguchi
Recurrence time is evaluated for some initial quantum states in the one-dimensional Bose gas with repulsive short-range interactions. In the relatively strong and weak coupling cas…
