Yang-Lee Edge Singularity on a Class of Treelike Lattices
arXiv:cond-mat/9612168 · doi:10.1088/0305-4470/30/6/031
Abstract
The density of zeros of the partition function of the Ising model on a class of treelike lattices is studied. An exact closed-form expression for the pertinent critical exponents is derived by using a couple of recursion relations which have a singular behavior near the Yang-Lee edge.
