The multivariate arithmetic Tutte polynomial [PDF]

Discrete Mathematics & Theoretical Computer Science, 2012
We introduce an arithmetic version of the multivariate Tutte polynomial recently studied by Sokal, and a quasi-polynomial that interpolates between the two.

The Potts Fully Frustrated model: Thermodynamics, percolation and dynamics in 2 dimensions [PDF]

, 2000
We consider a Potts model diluted by fully frustrated Ising spins. The model corresponds to a fully frustrated Potts model with variables having an integer absolute value and a sign.

ARITHMETIC OF POTTS MODEL HYPERSURFACES [PDF]

International Journal of Geometric Methods in Modern Physics, 2013
We consider Potts model hypersurfaces defined by the multivariate Tutte polynomial of graphs (Potts model partition function). We focus on the behavior of the number of points over finite fields for these hypersurfaces, in comparison with the graph hypersurfaces of perturbative quantum field theory defined by the Kirchhoff graph polynomial.

Potts model for haplotype associations [PDF]

BMC Genetics, 2005
Abstract Bayesian spatial modeling has become important in disease mapping and has also been suggested as a useful tool in genetic fine mapping. We have implemented the Potts model and applied it to the Genetic Analysis Workshop 14 (GAW14) simulated data.

Scaling in the vicinity of the four-state Potts fixed point [PDF]

, 2017
We study a self-dual generalization of the Baxter-Wu model, employing results obtained by transfer matrix calculations of the magnetic scaling dimension and the free energy.

The forgotten potts models [PDF]

Nuclear Physics B - Proceedings Supplements, 1995
The q=10 and q=200 state Potts models coupled to 2d gravity are investigated numerically and shown to have continuous phase transitions, contrary to their behavior on a regular lattice. Critical exponents are extracted and possible critical behavior for general q-state Potts models coupled to gravity is discussed.

Minimalistic real-space renormalization of Ising and Potts Models in two dimensions

Frontiers in Physics, 2015
We introduce and discuss a real-space renormalization group (RSRG) procedure on very small lattices, which in principle does not require any of the usual approximations, e.g. a cut-off in the expansion of the Hamiltonian in powers of the field.
