Zeros of the Partition Function for Higher–Spin 2D Ising Models

We present calculations of the complex-temperature zeros of the partition functions for 2D Ising models on the square lattice with spin s = 1, 3/2, and 2. These give insight into complex-temperature phase diagrams of these models in the thermodynamic limit. Support is adduced for a conjecture that all divergences of the magnetisation occur at endpoints of arcs of zeros protruding into the FM ph...

Complex Temperatures Zeroes of Partition Function in Spin-glass Models

An approximate method is proposed for investigating complex-temperature properties of real-dimensional spin-glass models. The method uses the complex-temperature data of the ferromagnetic model on the same lattice. The universality line in the complex-temperature space is obtained.

Partition function zeros in QCD

The spectral correlations of the QCD Dirac operator in the 4-dimensional Euclidean box, 1/ΛQCD ≪ L ≪ 1/mπ, usually denoted as Leutwyler-Smilga regime [3], have been the object of intense study in recent years. They contain valuable information about the chiral properties of the QCD vacuum. Provided that chiral symmetry is spontaneously broken, the above regime can be described either by an effe...

Complex Replica Zeros of ±J Ising Spin Glass at Zero Temperature

Zeros of the nth moment of the partition function [Z] are investigated in a vanishing temperature limit β → ∞, n → 0 keeping y = βn ∼ O(1). In this limit, the moment parameterized by y characterizes the distribution of the ground-state energy. We numerically investigate the zeros for ±J Ising spin glass models with tree and other several systems, which can be carried out with a feasible computa...

Theory of quantum annealing of an Ising spin glass.

Probing the lowest energy configuration of a complex system by quantum annealing was recently found to be more effective than its classical, thermal counterpart. By comparing classical and quantum Monte Carlo annealing protocols on the two-dimensional random Ising model (a prototype spin glass), we confirm the superiority of quantum annealing relative to classical annealing. We also propose a t...
