The tunneling phenomena of the Fermi superfluid gases in unitarity by manipulating the Fermi-Fermi scattering length

Abstract

In the present work, we investigate the tunneling dynamics of superfluid Fermi gas in a double-well potential in a unitarity regime by adjusting the Fermi-Fermi scattering length. The scattering length can affect the quantum transition dramatically. In a certain regime, the complete population transfer between two modes can be obtained. However, in some other regimes, the quantum transition can be completely blocked.
