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…
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…
