Abstract:

The generalized Schwinger representation of the fermion pairs is reformulated with the aim of investigating the applicability to the anharmonicity. Through this reformulation, the seniority quantum number and quasi-boson operator as the generator of higher seniority states are introduced into the Schwinger boson space. An approximate diagonalization of pairing Hamiltonian gives the same result as that of the BCS-Bogoliubov theory.
