The Transform Between Hubbard Operators and Pauli Matrices

WU Jun-fang, Zhang Chun-Min

Aim The Hamiltonian is transformed from Pauli matrices to Hubbard operators. Method we use the unity and orthogonal of Hubbard operators to give the transforming formula of Pauli matrices and Hubbard operators, by using these transforming formula we realize the change from Pauli matrices to Hubbard operators. Result we get the Hamiltonian expressed by Hubbard operators of the spin-ladder model. Conclusion We use the example to realize the transform between Hubbard operators and Pauli matrices.

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.
