Frustrating and diluting dynamical lattice Ising spins

Research output: Contribution to journalArticle

Abstract

We investigate what happens to the third order ferromagnetic phase transition displayed by the Ising model on various dynamical planar lattices (i e coupled to 2D quantum gravity) when we introduce annealed bond disorder in the form of either antiferromagnetic couplings or null couplings We also look at the effect of such disordering for the Ising model on general f3 and f4 Feynman diagrams.
