    T=0 Partition Functions for Potts Antiferromagnets on Moebius Strips and Effects of Graph Topology

    Full text link
    We present exact calculations of the zero-temperature partition function of the qq-state Potts antiferromagnet (equivalently the chromatic polynomial) for Moebius strips, with width Ly=2L_y=2 or 3, of regular lattices and homeomorphic expansions thereof. These are compared with the corresponding partition functions for strip graphs with (untwisted) periodic longitudinal boundary conditions.Comment: 9 pages, Latex, Phys. Lett. A, in pres
