Contribution

It introduces the concept of cyclic fermion pairing states and analyzes their behavior across Feshbach resonances in optical lattices.

Findings

Pairing amplitude oscillates with detuning.

Quasi-particle gaps vary across resonance regimes.

Cyclic fermion pairing states are theoretically characterized.

Abstract

In this Letter we illustrate the possible cyclic fermion pairing states across Feshbach resonances in optical lattices. In cyclic fermion pairing, the pairing amplitude exhibits an oscillatory behavior as the detuning varies. We estimate the quasi-particle gaps in different regimes of the resonances.
