Abstract
We consider a gas of neutral fermions trapped in a specific optical trap that provides a tight confinement of a Fermi gas in a torus with a potential periodic along the azimuthal direction. The effective model is interacting fermions moving in a periodic potential along the ring. We show that the model demonstrates a novel type of superfluidity different from the BCS mechanism. This pure 1D quantum gas in a ring can also form crystalline structures with both ferro- and antiferro-magnetic type orders. Possibilities of realization of quantum crystals and their application for quantum computing are discussed.
