One possibility is a fully paired state with a gap for fermion excitations in which the Cooper pairs remain uncondensed. Such a \"Cooper-pair Bose-metal\" phase would be expected to have a singular Bose-surface in momentum space. As demonstrated in the context of 2D bosons hopping with a frustrating ring-exchange interaction, an analogous Bose-metal phase has a set of quasi-1D descendent states wh","authors_text":"Adrian E.
