Cooper pair dispersion relation in two dimensions
arXiv:cond-mat/0004020 · doi:10.1016/S0921-4534(00)00422-6
Abstract
The Cooper pair binding energy {\it vs.} center-of-mass-momentum dispersion relation for Bose-Einstein condensation studies of superconductivity is found in two dimensions for a renormalized attractive delta interaction. It crosses over smoothly from a linear to a quadratic form as coupling varies from weak to strong.
