Nonliner Landau-Zener tunneling of a Bose-Fermi mixture

Abstract

In this paper we study the nonlinear Landau-Zener tunneling of a boson-fermion mixture in a double-well potential by adjusting the interaction parameter of its components. We find that the tunneling in the system can be affected by adjusting the interatomic self-interaction parameter. Moreover, we notice that the tunneling in the system show a critical phenomenon if variation of interatomic self-interaction, and critical point are given.
