Phase structure of XX0 spin chain and nonintersecting Brownian motion
Phase structure of XX0 spin chain and nonintersecting Brownian motion
We study finite size and temperature XX0 Heisenberg spin chain in weak and strong coupling regimes. By using an elegant connection of the model to integrable combinatorics and probability, we explore and interpret a possible phase structure of the model in asymptotic limit: the limit of large inverse temperature and …
