Correlation Function of the Spin - 1 / 2 XXX
We consider a special correlation function in the isotropic spin-1 2 Heisenberg antiferromagnet. It is the probability of nding a ferromagnetic string of (adjacent) spins in the antiferromagnetic ground state. We give two diierent representations for this correlation function. Both of them are exact at any distance, but one becomes more eeective for the description of long distance behaviour, t...
متن کاملCorrelation functions of the higher spin XXX chains
Using the Algebraic Bethe Ansatz we consider the correlation functions of the integrable higher spin chains. We apply a method recently developed for the spin 12 Heisenberg chain, based on the solution of the quantum inverse problem. We construct a representation for the correlation functions on a finite chain for arbitrary spin. Then we show how the string solutions of the Bethe equations can ...
متن کاملThe Spin - Spin Correlation Function in the Two - Dimensional Ising
The form factor bootstrap approach is used to compute the exact contributions in the large distance expansion of the correlation function < σ(x)σ(0) > of the twodimensional Ising model in a magnetic field at T = Tc. The matrix elements of the magnetization operator σ(x) present a rich analytic structure induced by the (multi) scattering processes of the eight massive particles of the model. The...
متن کاملSpin Liquid Phase in the Pyrochlore Antiferromagnet
Correlation functions (CFs) of the classical Heisenberg antiferromagnet on the pyrochlore lattice are studied by solving exactly the infinite-component spin-vector model. As in many Fully Frustrated Lattices, the constraint due to the minimization of the energy and the particular structure based on corner sharing tetrahedra both contribute to the creation of local degrees of freedom. The result...
متن کاملOn the Baxter's Q -operator for the Xxx Spin Chain
We discuss the construction of Baxter's Q-operator. The suggested approach leads to the one-parametric family of Q-operators, satisfying to the wronslian-type relations. Also we have found the generalization of Baxter operators, with defines the nondiagonal part of the monodromy.
