Yang–Lee zeros of the Yang–Lee model

To understand the distribution of the Yang–Lee zeros in quantum integrable field theories we analyse the simplest of these systems given by the 2D Yang– Lee model. The grand-canonical partition function of this quantum field theory, as a function of the fugacity z and the inverse temperature β, can be computed in terms of the thermodynamics Bethe Ansatz based on its exact S-matrix. We extract t...

Yang-Lee Edge Singularity of the Infinite-Range Ising Model

The Ising ferromagnet, consisting of magnetic spins, is the simplest system showing phase transitions and critical phenomena at finite temperatures. The Ising ferromagnet has played a central role in our understanding of phase transitions and critical phenomena. Also, the Ising ferromagnet explains the gas-liquid phase transitions accurately. In particular, the Ising ferromagnet in a nonzero ma...

Lee-Yang edge singularity in the three-dimensional Gross-Neveu model at finite temperature

We discuss the relevance of the Lee-Yang edge singularity to the finite-temperature Z2-symmetry restoration transition of the Gross-Neveu model in three dimensions. We present an explicit result for its large-N free-energy density in terms of ζ(3) and the absolute maximum of Clausen’s function. The Gross-Neveu model in d = 3 dimensions provides a remarkable example of a second order temperature...

Correlation functions of descendants in the scaling Lee–Yang model

Correlation functions of the composite field T T̄ in the scaling Lee–Yang model are studied. Using the analytic expression for form factors of this operator recently proposed by Delfino and Niccoli [1], we show numerically that the constraints on the T T̄ expectation values obtained in [2] and the additional requirement of asymptotic behavior lead to a perfect agreement with the ultraviolet asymp...

Yang-Lee zeros of a random matrix model for QCD at finite density

We study the Yang-Lee zeros of a random matrix partition function with the global symmetries of the QCD partition function. We consider both zeros in the complex chemical potential plane and in the complex mass plane. In both cases we find that the zeros are located on a curve. In the thermodynamic limit, the zeros appear to merge to form a cut. The shape of this limiting curve can be obtained ...
