Correlated Pair Approach to Composite Boson Scattering Lengths

11 Oct 2016 Shiau Shiue-Yuan Combescot Monique Chang Yia-Chung

We derive the scattering length of composite bosons (cobosons) within the framework of the composite boson many-body formalism that uses correlated-pair states as a basis, instead of free fermion states. The integral equation constructed from this physically relevant basis makes transparent the role of fermion exchange in the coboson-coboson effective scattering... (read more)
