Ising model on nonorientable surfaces: Exact solution for the Moebius strip and the Klein bottle

arXiv:cond-mat/0007325 · doi:10.1103/PhysRevE.63.026107

Abstract

Closed-form expressions are obtained for the partition function of the Ising model on an M x N simple-quartic lattice embedded on a Moebius strip and a Klein bottle for finite M and N. The finite-size effects at criticality are analyzed and compared with those under cylindrical and toroidal boundary conditions. Our analysis confirms that the central charge is c=1/2.
