Abstract

A new formulation for deriving the squeezing fermion-pair operators, which manifestly shows the correspondence between pseudo-classical transformation in Grassmann number space and quantum mechanical Fermi operators, is presented. In this formulation new fermionic operator formulas regarding Bogoliubov-Valatin transformation are obtained.
