Quantum spin systems occupy a central role in understanding magnetic phenomena and phase transitions at the microscopic level. In these systems, intrinsic angular momentum (spin) interactions give ...

We study the distribution of cycle lengths in models of nonuniform random permutations with cycle weights. We identify several regimes. Depending on the weights, the length of typical cycles grows ...
