Condensation in the Backgammon model

P. Bialas, Z. Burda, D. Johnston

We analyse the properties of a very simple ``balls-in-boxes'' model which can exhibit a phase transition between a fluid and a condensed phase, similar to behaviour encountered in…

Softening Transitions with Quenched 2D Gravity

C. F. Baillie, W. Janke, D. A. Johnston

We perform extensive Monte Carlo simulations of the 10-state Potts model on quenched two-dimensional gravity graphs to study the effect of quenched connectivity disorder on t…

Theory of anyon excitons: Relation to excitons of nu=1/3 and nu=2/3 incompressible liquids

M. E. Portnoi, E. I. Rashba

Elementary excitations of incompressible quantum liquids (IQL's) are anyons, i.e., quasiparticles carrying fractional charges and obeying fractional statistics. To find out how the…

Softening of First-Order Phase Transition on Quenched Random Gravity Graphs

C. F. Baillie, W. Janke, D. A. Johnston

We perform extensive Monte Carlo simulations of the 10-state Potts model on quenched two-dimensional gravity graphs to study the effect of quenched coordination number random…

Gravity and Random Surfaces on the Lattice - A Review

D. A. Johnston

We review recent work in the lattice approach to random surfaces and quantum gravity. Our task is made somewhat easier by some very interesting results, particularly in four dimens…

Gonihedric Ising Actions

D. A. Johnston, R. P. K. C. Malmini

We discuss a generalized Ising action containing nearest neighbour, next to nearest neighbour and plaquette terms that has been suggested as a potential string worldsheet discretiz…
