introduction
  • XXZ spin chain and the six-vertex transfer matrix have the same eigenvectors
  • Boltzmann weights
  • monodromy matrix
  • trace of monodromy matrix is the transfer matrix
  • power of transfer matrix becomes the partition function

 

 

types of six vertex models
  • on a square lattice with periodic boundary conditions
  • on a square lattice with domain wall boundary conditions 

 

 

transfer matrix
  • finding eigenvalues and eigenvectors of transfer matrix is crucial
  • Bethe ansatz equation is used to find the eigenvectors and eigenvalues

 

 

anistropic one-dimensional Heisenberg model
  • XXZ model
  • first solved by Bethe 
  • Yang and Yang
  • ground state eigevector for Hamiltonian  is a common eigenvector

 

 

partition function

 

 

free energy
  • \(F=-kT \ln Z\)

 

 

correlation functions
