Abstract

By considering the contribution of the higher order term representing the lowest approximation of beyond mean field corrections, we have investigated the effect of energy bias to the Josephson oscillation and self-trapping of superfluid Fermi gases in a double-well potential in deep BEC regime. Five phase states of Josephson oscillation (JO), oscillation-phase-type-self-trapping (OPTST), similar-oscillation-phase-type-self-trapping (SOPTST), running-phase-type-self-trapping (RPTST) and similar-running-phase-type-self-trapping (SRPTST) are found. The dependence of these five phase states on the dimensionless interaction parameter y = 1/(k_Fa_sc) and the initial system energy are given in this paper.
