Communal pairing in superconductors introduces variational freedom for Cooper
pairs to share fermions. Temporal oscillations of the superconducting gap
entropically drive communal pairing through the order by disorder
phenomenology, stabilising a finite momentum space width of the superconducting
gap that increases with interaction strength, creating a smooth evolution from
the weakly interacting BCS state to the strongly interacting BEC state.Royal Society and the National University of Singapor
