Properties of phase transitions of higher order
W. Janke, D. A. Johnston, R. Kenna
There is only limited experimental evidence for the existence in nature of phase transitions of Ehrenfest order greater than two. However, there is no physical reason for their non…
New methods to measure phase transition strength
Wolfhard Janke, Des Johnston, Ralph Kenna
A recently developed technique to determine the order and strength of phase transitions by extracting the density of partition function zeroes (a continuous function) from finite-s…
Fat and Thin Fisher Zeroes
W. Janke, D. Johnston, M. Stathakopoulos
We show that it is possible to determine the locus of Fisher zeroes in the thermodynamic limit for the Ising model on planar (``fat'') phi4 random graphs and their dual quadrangula…
Finite size scaling of the balls in boxes model
P. Bialas, L. Bogacz, Z. Burda +1
We discuss the finite size behaviour in the canonical ensemble of the balls in boxes model. We compare theoretical predictions and numerical results for the finite size scaling of…
Ising and Potts Models on Quenched Random Gravity Graphs
W. Janke, D. Johnston
We report on single-cluster Monte Carlo simulations of the Ising, 4-state Potts and 10-state Potts models on quenched ensembles of planar, tri-valent random graphs. We confirm that…
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…
