We propose an alternative way to describe the pairing formation and breaking via a quantum
\nanharmonic oscillator with a delta-function potential model. Unlike BCS theory, which describes the
\npairing formation in the momentum space, this model works in the coordinate space and is able to
\ngive a molecular view of pairing formation and breaking in the coordinate space. By exploring the
\ndynamical interplay between the intrinsic factor (dissociation energy) and external factor (pairing
\nstrength) of this system additional information was gained, including the critical pairing strength
\nand critical scattering length, which might relate to the BCS\u2013BEC crossover phenomena and halo state
\nformation. Although only the energetic aspect of pairing is described by this model, its simplicity
\nand pedagogical steps might help undergraduate students to understand the pairing problem in a
\nsimple way.<\/p>\n","protected":false},"excerpt":{"rendered":"
