Correlation Functions for Lattice Integrable Models

Correlation Functions for Lattice Integrable Models

In this lectures I consider the problem of calculating the correlation functions for XXZ spin chain. First, I explain in details the free fermion case. Then I show that for generic coupling constant the fermionic operators acting on the space of quasi-local fields can be introduced. In the basis gen...
