The Information Geometry of the Spherical Model
W. Janke, D. A. Johnston, R. Kenna
Motivated by previous observations that geometrizing statistical mechanics offers an interesting alternative to more standard approaches,we have recently calculated the curvature (…
Patterns in randomly evolving networks: Idiotypic networks
M. Brede, U. Behn
We present a model for the evolution of networks of occupied sites on undirected regular graphs. At every iteration step in a parallel update I randomly chosen empty sites are occu…
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…
Star-graph expansions for bond-diluted Potts models
Meik Hellmund, Wolfhard Janke
We derive high-temperature series expansions for the free energy and the susceptibility of random-bond -state Potts models on hypercubic lattices using a star-graph expansion te…
Overlap Distribution of the Three-Dimensional Ising Model
Bernd A. Berg, Alain Billoire, Wolfhard Janke
We study the Parisi overlap probability density P_L(q) for the three-dimensional Ising ferromagnet by means of Monte Carlo (MC) simulations. At the critical point P_L(q) is peaked…
Density of Partition Function Zeroes and Phase Transition Strength
Wolfhard Janke, Ralph Kenna
A new method to extract the density of partition function zeroes (a continuous function) from their distribution for finite lattices (a discrete data set) is presented. This allows…
