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…
Asymmetry-induced delocalization transition in the integrable non-Hermitian spin chain
Yuki Ishiguro, Jun Sato, Katsuhiro Nishinari
The emergence of quasiparticles is a universal property in integrable systems. String-type quasiparticles, which are characterized by the string solutions of Bethe equations, play…
Burgers equation with finite particle correction of the asymmetric simple exclusion process derived from the derivative nonlinear Schrödinger equation
Yuki Ishiguro, Jun Sato, Katsuhiro Nishinari
We investigate the dynamics of the asymmetric simple exclusion process (ASEP) on a ring. The ASEP is equivalent to the derivative nonlinear Schrödinger equation (DNLS), which is in…
Quantum-classical correspondence via coherent state in integrable field theory
Jun Sato, Tsukasa Yumibayashi
We consider the problem of quantum-classical correspondence in integrable field theories. We propose a method to construct a field theoretical coherent state, in which the expectat…
