Description
Models with matter coupled to two dimensional CDT are hard to solve analytically, somewhat contrasting with matter coupled to dynamical triangulations which can be solved by a plethora of methods. Recently Atkin and Zohren introduced a restricted dimer model which can be solved. I’ll discuss some of its bizarre characteristics and introduce a generalisation that is also solvable and shows these to be somehow non-generic. Finally I’ll discuss whether these results are really representative in the continuum limit of a field theory coupled to 2d gravity.
