We investigate single-particle excitations at T = 0 in the BCS-BEC crossover regime of a superfluid Fermi gas. We solve the Bogoliubov-de Gennes equations in a trap, including a tunable pairing interaction associated with a Feshbach resonance. We show that the single-particle energy gap E g is domin

## Abstract The effect of dilution of the chiral stationary phase octakis (3‐O‐butyryl‐2, 6‐di‐O‐pentyl)‐γ‐cyclodextrin in the achiral polysiloxane OV–1701 on the separation factor was investigated over a wide concentration range. The loss in enantioselectivity was only negligible down to a dilutio
