Quenching 2D quantum gravity

We simulate the Ising model on a set of fixed random ø 3 graphs, which corresponds to a quenched coupling to 2D gravity rather than the annealed coupling that is usually considered. We investigate the critical exponents in such a quenched ensemble and compare them with measurements on dynamical ø 3...

Description
Summary:We simulate the Ising model on a set of fixed random ø 3 graphs, which corresponds to a quenched coupling to 2D gravity rather than the annealed coupling that is usually considered. We investigate the critical exponents in such a quenched ensemble and compare them with measurements on dynamical ø 3 graphs, flat lattices and a single fixed ø 3 graph.
