Fixed boundary conditions and phase transitions in pure gauge compact QED
arXiv:hep-lat/9406003 · doi:10.1016/0370-2693(94)91276-9
Abstract
We have simulated the pure gauge compact QED with fixed boundary conditions, on lattices from to . We argue that a lattice with this fixed boundary imposition corresponds actually to a lattice with spherical topology. We have found the presence of a phase transition without any trace of discontinuity. Moreover, the specific heat and the Binder cumulant are qualitatively consistent with a second order phase transition. The implications of this observation on the nature of the compact lattice QED are discussed.
