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…
Ising spins coupled to a four-dimensional discrete Regge skeleton
E. Bittner, W. Janke, H. Markum
Regge calculus is a powerful method to approximate a continuous manifold by a simplicial lattice, keeping the connectivities of the underlying lattice fixed and taking the edge len…
Exact finite-size scaling with corrections in the two-dimensional Ising model with special boundary conditions
Wolfhard Janke, Ralph Kenna
The two-dimensional Ising model with Brascamp-Kunz boundary conditions has a partition function more amenable to analysis than its counterpart on a torus. This fact is exploited to…
The Wrong Kind of Gravity
W. Janke, D. Johnston
The KPZ formula shows that coupling central charge less than one spin models to 2D quantum gravity dresses the conformal weights to get new critical exponents, where the relation b…
Z_2-Regge versus Standard Regge Calculus in two dimensions
E. Bittner, A. Hauke, H. Markum +3
We consider two versions of quantum Regge calculus. The Standard Regge Calculus where the quadratic link lengths of the simplicial manifold vary continuously and the Z_2-Regge Mode…
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…
