Interplay between sign problem and Z_3 symmetry in three-dimensional Potts model

Takehiro Hirakida, Hiroaki Kouno, Junichi Takahashi +1

We construct four kinds of Z3-symmetric three-dimentional (3-d) Potts models, each with different number of states at each site on a 3-d lattice, by extending the 3-d three-state P…
