Remarks on the Bose description of the Pauli spin operators
Abstract
Using both the fermionic-like and the bosonic-like properties of the Pauli spin operators we discuss the Bose description of the Pauli spin operators firstly proposed by Shigefumi Naka, and derive another new bosonic representation of the Pauli spin operators. The eigenvector of σ- in the bosonic representation is a nonlinear coherent state with the eigenvalues being the Grassmann numbers.
