Partition Function Zeros of Paths and Normalization Zeros of ASEPS
Zdzislaw Burda, Desmond A. Johnston
We exploit the equivalence between the partition function of an adsorbing Dyck walk model and the Asymmetric Simple Exclusion Process (ASEP) normalization to obtain the thermodynam…
Yang-Lee zeros for real-space condensation
Zdzislaw Burda, Desmond A. Johnston, Mario Kieburg
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-spac…
Partition function zeros of zeta-urns
P. Bialas, Z. Burda, D. A. Johnston
We discuss the distribution of partition function zeros for the grand-canonical ensemble of the zeta-urn model, where tuning a single parameter can give a first or any higher order…
Potts Models with Invisible States on General Bethe Lattices
N. Ananikian, N. Sh. Izmailyan, D. A. Johnston +2
The number of so-called invisible states which need to be added to the q-state Potts model to transmute its phase transition from continuous to first order has attracted recent att…
Potts Models with (17) Invisible States on Thin Graphs
D. A. Johnston, R. P. K. C. M. Ranasinghe
The order of a phase transition is usually determined by the nature of the symmetry breaking at the phase transition point and the dimension of the model under consideration. For i…
The Dual Gonihedric 3D Ising Model
D. A. Johnston, R. P. K. C. M. Ranasinghe
We investigate the dual of the kappa=0 Gonihedric Ising model on a 3D cubic lattice, which may be written as an anisotropically coupled Ashkin-Teller model. The original kappa=0 Go…
