Transfer matrices and partition-function zeros for antiferromagnetic Potts models. VI. Square lattice with special boundary conditions
Jesús Salas, Alan D. Sokal
We study, using transfer-matrix methods, the partition-function zeros of the square-lattice q-state Potts antiferromagnet at zero temperature (= square-lattice chromatic polynomial…
Complex-temperature phase diagram of Potts and RSOS models
Jesper Lykke Jacobsen, Jean-Francois Richard, Jesus Salas
We study the phase diagram of Q-state Potts models, for Q=4 cos^2(PI/p) a Beraha number (p>2 integer), in the complex-temperature plane. The models are defined on L x N strips of t…
Exact Finite-Size-Scaling Corrections to the Critical Two-Dimensional Ising Model on a Torus. II. Triangular and hexagonal lattices
J. Salas
We compute the finite-size corrections to the free energy, internal energy and specific heat of the critical two-dimensional spin-1/2 Ising model on a triangular and hexagonal latt…
Exact Finite-Size-Scaling Corrections to the Critical Two-Dimensional Ising Model on a Torus
J. Salas
We analyze the finite-size corrections to the energy and specific heat of the critical two-dimensional spin-1/2 Ising model on a torus. We extend the analysis of Ferdinand and Fish…
Tricritical Behavior of Two-Dimensional Scalar Field Theories
M. Asorey, J. G. Esteve, F. Falceto +1
We compute by Monte Carlo numerical simulations the critical exponents of two-dimensional scalar field theories at the tricritical point. The results are in agreement with t…
Low--Temperature Series for Renormalized Operators: the Ferromagnetic Square--Lattice Ising Model.
J. Salas
A method for computing low--temperature series for renormalized operators in the two--dimensional Ising model is proposed. These series are applied to the study of the properties o…
