Summary

The study investigates quantum spin transport in a one-dimensional folded XXZ model using the Bethe ansatz technique, finding that the probability distribution of the left-most up-spin converges to the Tracy-Widom distribution for the Gaussian unitary ensemble (GUE) in the long-time limit.

  • The Bethe ansatz technique is used to derive an exact expression for the probability distribution of the left-most up-spin.
  • The probability distribution is found to converge to the GUE Tracy-Widom distribution in the long-time limit.
  • The GUE Tracy-Widom distribution is a universal distribution that appears in various physical systems.
  • The study's findings suggest that the folded XXZ model exhibits similar behavior to other integrable models.
  • The results have implications for understanding the behavior of interacting quantum systems.
  • The study provides a new example of the GUE Tracy-Widom distribution in a quantum system.
