The Transformation of Hamiltonian of Anisotropic Spin-ladder Model Between Pauli Operators and Hubbard Operators

WU Jun-fang, Zhang Chun-Min

Abstract

This paper used the unity and orthogonal of Hubbard operators to give the transforming formula of Pauli operators and Hubbard operators, by using these transforming formula we realize the change from Pauli operators to Hubbard operators. We get the Hamiltonian of the anisotropic spin-ladder model expressed by Hubbard operators. We use the example to realize the transform between Hubbard operators and Pauli operators.
