An approximation for random surfaces on arbitrary target spaces
Mark Wexler
A perturbative technique, the low-temperature expansion, is developed for matrix models of random surfaces. It can be applied to models with arbitrary target spaces, including ones…
New critical phenomena in 2d quantum gravity
Jan Ambjorn, Gudmar Thorleifsson, Mark Wexler
We study and state Potts models on dynamical triangulated lattices and demonstrate that these models exhibit continuous phase transitions, contrary to the first orde…
Matrix Models on Large Graphs
Mark Wexler
We consider the spherical limit of multi-matrix models on regular target graphs, for instance single or multiple Potts models, or lattices of arbitrary dimension. We show, to all o…
Low Temperature Expansion of Matrix Models
Mark Wexler
We show how to expand the free energy of a matrix model coupled to arbitrary matter in powers of the matter coupling constant. Concentrating on uncoupled Ising models---which h…
