Unconventional Universality Class of One-Dimensional Isolated Coarsening Dynamics in a Spinor Bose Gas.

Kazuya Fujimoto, Ryusuke Hamazaki, Masahito Ueda

By studying the coarsening dynamics of a one-dimensional spin-1 Bose-Hubbard model in a superfluid regime, we analytically find an unconventional universal dynamical scaling for the growth of the spin correlation length, which is characterized by the exponential integral unlike the conventional power-law or simple logarithmic behavior, and numerically confirmed with the truncated Wigner approximation.
