摘要：
A new formulation of the Bogoliubov-Valatin transformation explicitly parameter-dependent and with no quasiparticle operators is derived and applied to a diagonalization of the BCS reduced Hamiltonian in the particle space. It is shown that the eigenstates of this Hamiltonian are just the BCS states and are a kind of squeezed fermion-pair states as well. © EDP Sciences Springer-Verlag 1998.
