Some new results on Yang-Lee zeros of the Ising model partition function

We prove that for the Ising model on a lattice of dimensionality d 2 2, the zeros of the partition function 2 in the complex p plane (where ,u = e -2PH) lie on the unit circle j,~l = 1 for a wider range of K,,/ = /3J,,,*t than the range K,,,,, 3 0 assumed in the premise of the Yang-Lee circle theorem. This range includes complex temperatures, and we show that it is lattice-dependent. Our result...

The scaling supersymmetric Yang-Lee model with boundary

We define the scaling supersymmetric Yang-Lee model with boundary as the (1 , 3) perturbation of the superconformal minimal model SM(2/8) (or equivalently, the (1 , 5) perturbation of the conformal minimal modelM(3/8)) with a certain conformal boundary condition. We propose the corresponding boundary S matrix, which is not diagonal for general values of the boundary parameter. We argue that the...

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 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...

mortality forecasting based on lee-carter model

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
