The Transformation Between Hubbard Operators and Pauli Matrices

WU Jun-fang

Abstract

Aiming at the transformation of Hamiltonian from Pauli matrices to Hubbard operators, the authors use the unity and orthogonal of Hubbard operators to give the transforming formula of Pauli matrices and Hubbard operators, by which, they realize the change from Pauli matrices to Hubbard operators.The result has been obtained that the Hamiltonian expressed by Hubbard operators of the spin-ladder model.
