Imposing causality on a matrix model

arXiv:0812.4261 · doi:10.1016/j.physletb.2009.06.027

Abstract

We introduce a new matrix model that describes Causal Dynamical Triangulations (CDT) in two dimensions. In order to do so, we introduce a new, simpler definition of 2D CDT and show it to be equivalent to the old one. The model makes use of ideas from dually weighted matrix models, combined with multi-matrix models, and can be studied by the method of character expansion.

9 pages, 2 figures; slightly extended version with more details on the character expansion
