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…
