We introduce an extension of the diagrammatic rules in random matrix theory and apply it to
non-hermitian random matrix models using the 1/N approximation. A number of one-and two …

We present a numerical calculation of the Lee-Yang and Fisher zeros of the 2D Ising model
using multipoint Padé approximants. We perform simulations for the 2D Ising model with …

We calculate the value of the coupling at the infrared zero of the beta function of an
asymptotically free SU (3) gauge theory at the five-loop level as a function of the number of …

Phase transitions were recognized among the most fascinating phenomena in physics.
Exactly solved models are especially important in the theory of phase transitions. A number …

We present and analyse low-temperature series and complex-temperature partition function
zeros for the q-state Potts model with q= 4 on the honeycomb lattice and q= 3, 4 on the …

Using the electrostatic analogy, we derive an exact formula for the limiting Yang-Lee zero
distribution in the random allocation model of general weights. This exhibits a real-space …

We present exact calculations of the partition function Z of the q-state Potts model and its
generalization to real q, for arbitrary temperature on n-vertex ladder graphs, ie, strips of the …

Some simplifications of the integrals (2n+ 1), derived by Wu et al (1976 13 316), that
contribute to the zero field susceptibility of the 2D square lattice Ising model are reported. In …

We study the confinement scenario in N= 2 supersymmetric SU (2) gauge theory near the
monopole point upon breaking of N= 2 supersymmetry by the adjoint matter mass term. We …

We study the q-state Potts model with nearest-neighbor coupling v= e βJ− 1 in the limit q, v→
0 with the ratio w= v/q held fixed. Combinatorially, this limit gives rise to the generating …
