DMRG and effective-pairing theory show insulating regions with persistent superfluid correlations in trapped 1D Fermi-Hubbard chains, with conditioned correlation functions distinguishing BCS-like from BEC-like behavior.
The layer-antisymmetric pair-phase resonance sits at the bonding-antibonding splitting 2t_h because the antisymmetric bubble reduces pointwise to the static symmetric bubble at that frequency.
