The cylinder amplitude in the Hard Dimer model on 2D Causal Dynamical Triangulations
arXiv:2109.04414 · doi:10.1088/1361-6382/ac50ec
Abstract
We consider the model of hard dimers coupled to two-dimensional Causal Dynamical Triangulations (CDT) with all dimer types present and solve it exactly subject to a single restriction. Depending on the dimer weights there are, in addition to the usual gravity phase of CDT, two tri-critical and two dense dimer phases. We establish the properties of these phases, computing their cylinder and disk amplitudes, and their scaling limits.
