Abstract
We reconsider the bipolaronic system by introducing the squeezed-polaron model or two-phonon coherent state, and obtain more satisfactory results than before with respect to lowering the system's ground-state energy and extending the singlet superconducting phase in the phase diagram of such a bipolaronic system. The necessity and the limit of using our variational treatment to this bipolaronic system are also discussed.
