Correlation functions of descendants in the scaling Lee–Yang model

چکیده
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 asymptotic predicted by the conformal perturbation theory.

Dimensional Reduction Formulas for Branched Polymer Correlation Functions
In [BI01] we have proven that the generating function for self-avoiding branched polymers in D + 2 continuum dimensions is proportional to the pressure of the hardcore continuum gas at negative activity in D dimensions. This result explains why the critical behavior of branched polymers should be the same as that of the iφ3 (or Yang-Lee edge) field theory in two fewer dimensions (as proposed by...
متن کاملUsing shifted Legendre scaling functions for solving fractional biochemical reaction problem
In this paper, biochemical reaction problem is given in the form of a system of non-linear differential equations involving Caputo fractional derivative. The aim is to suggest an instrumental scheme to approximate the solution of this problem. To achieve this goal, the fractional derivation terms are expanded as the elements of shifted Legendre scaling functions. Then, applying operational matr...
متن کاملLogarithmic Corrections to Scaling in the Two Dimensional XY –Model
By expressing thermodynamic functions in terms of the edge and density of Lee–Yang zeroes, we relate the scaling behaviour of the specific heat to that of the zero field magnetic susceptibility in the thermodynamic limit of the XY –model in two dimensions. Assuming that finite–size scaling holds, we show that the conventional Kosterlitz–Thouless scaling predictions for these thermodynamic funct...
متن کاملLogarithmic Corrections for Spin Glasses, Percolation and Lee-Yang Singularities in Six Dimensions
We study analytically the logarithmic corrections for the correlation length, susceptibility and specific heat in temperature as well as in the lattice size, for a generic φ3 theory at its upper critical dimension (six). We have also computed the leading correction to the scaling as a function of the lattice size. We distinguish the obtained formulas to the following special cases: percolation,...
متن کاملOn the relations between correlation functions in SYM/pp–wave correspondence
In this note we establish the explicit relation between correlation functions in N = 4 SUSY Yang–Mills theory on S3×R in a double scaling limit and scattering amplitudes of the String Theory on the pp-wave background. The relation is found for two– and three– point correlation functions in these theories. As a by product we formulate a dictionary for the correspondence between these theories: i...
