On two-point correlation functions in AdS/QCD
In this paper we study the chiral symmetry breaking in the hard wall AdS/QCD model. We solve the equations of motion up to the second order at large momentum and obtain the first few terms in the expansion of the ”left-right” correlator, which is the measure of symmetry breaking. In the strong coupling calculation we get the result as the series in square root of t’Hooft constant.
متن کاملN - point Correlation Functions of the Spin - 1 XXZ Model
We extend the recent approach of M. Jimbo, K. Miki, T. Miwa, and A. Nakayashiki to derive an integral formula for the N-point correlation functions of arbitrary local operators of the antiferromagnetic spin-1 XXZ model. For this, we realize the quantum affine symmetry algebra Uq(su(2)2) of level 2 and its corresponding type I vertex operators in terms of a deformed bosonic field free of a backg...
متن کاملCorrelation functions in the two-dimensional random-field Ising model.
Transfer-matrix methods are used to study the probability distributions of spin-spin correlation functions G in the two-dimensional random-field Ising model, on long strips of width L=3-15 sites, for binary field distributions at generic distance R, temperature T, and field intensity h(0). For moderately high T, and h(0) of the order of magnitude used in most experiments, the distributions are ...
متن کاملEnhanced pair correlation functions in the two- dimensional Hubbard model
In this study we have computed the pair correlation functions in the two-dimensional Hubbard model using a quantum Monte Carlo method. We employ a new diagonalization algorithm in the quantum Monte Carlo method which is free from the negative sign problem. We show that the d-wave pairing correlation function is indeed enhanced slightly for the positive on-site Coulomb interaction U when doping ...
متن کاملCorrelation functions in the two-dimensional random-bond Ising model.
We consider long strips of finite width L ≤ 13 sites of ferromagnetic Ising spins with random couplings distributed according to the binary distribution: P (Jij) = 1 2(δ(Jij − J0) + δ(Jij − rJ0)), 0 < r < 1. Spin-spin correlation functions < σ0σR > along the “infinite” direction are computed by transfer-matrix methods, at the critical temperature of the corresponding two-dimensional system, and...
