introduction
- ice-type model, R model, Rys model
- 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
- this is related to the Alternating sign matrix theorem
transfer matrix
- finding eigenvalues and eigenvectors of transfer matrix is crucial
- Bethe ansatz equation is used to find the eigenvectors and eigenvalues of the transfer matrix
- partition function is calculated in terms of the eigenvalues of the transfer matrix
- the below is from Yang-Baxter equation
- transfer matrix is builtup from matrices of Boltzmann weights
- we need the trasfer matrices coming from different set of Boltzman weights commute
- partition function = trace of power of transfer matrices
- so the problem of solving the model is reduced to the computation of this trace
entropy of two-dimensional ice
- entropy is given as
\(Mk\ln W\) where M is the number of molecules and \(W=(4/3)^{3/2}\)
free energy
- \(F=-kT \ln Z\)
partition function
correlation functions
anistropic one-dimensional Heisenberg model
- Heisenberg spin chain model
- XXZ model or XXZ spin chain
- first solved by Bethe
- Yang and Yang
- ground state eigevector for Hamiltonian is a common eigenvector
