(Four) Dual Plaquette 3D Ising Models
Desmond A. Johnston, R. P. K. C. M. Ranasinghe
A characteristic feature of the 3d plaquette Ising model is its planar subsystem symmetry. The quantum version of this model has been shown to be related via a duality to the X-Cub…
Potts Models with Invisible States on General Bethe Lattices
N. Ananikian, N. Sh. Izmailyan, D. A. Johnston +2
The number of so-called invisible states which need to be added to the q-state Potts model to transmute its phase transition from continuous to first order has attracted recent att…
Potts Models with (17) Invisible States on Thin Graphs
D. A. Johnston, R. P. K. C. M. Ranasinghe
The order of a phase transition is usually determined by the nature of the symmetry breaking at the phase transition point and the dimension of the model under consideration. For i…
The Dual Gonihedric 3D Ising Model
D. A. Johnston, R. P. K. C. M. Ranasinghe
We investigate the dual of the kappa=0 Gonihedric Ising model on a 3D cubic lattice, which may be written as an anisotropically coupled Ashkin-Teller model. The original kappa=0 Go…
The Gonihedric Ising Model and Glassiness
D. A. Johnston, A. Lipowski, Ranasinghe P. K. C. Malmini
The Gonihedric 3D Ising model is a lattice spin model in which planar Peierls boundaries between + and - spins can be created at zero energy cost. Instead of weighting the area of…
The Information Geometry of the Ising Model on Planar Random Graphs
W. Janke, D. A. Johnston, Ranasinghe P. K. C. Malmini
It has been suggested that an information geometric view of statistical mechanics in which a metric is introduced onto the space of parameters provides an interesting alternative c…
Decorating Random Quadrangulations
D. A. Johnston, R. P. K. C. Malmini
On various regular lattices (simple cubic, body centred cubic..) decorating an edge with an Ising spin coupled by bonds of strength L to the original vertex spins and competing wit…
