The Dirac Operator Coupled to 2D Quantum Gravity

L. Bogacz

We implement fermions on 2D dynamical random triangulation and determine the spectrum of the Dirac operator. We study the dependence of the spectrum on the hopping parameter and use finite size analysis to determine critical exponents. The results for regular, for Euclidean and for Lorentzian lattices are briefly presented.
