    在有相互作用的非线性两模系统中,通过对相互作用参数的调节,研究了该系统中玻色-费米混合气体的Landau-Zener隧穿现象.研究发现,其中某一组分的自相互作用会影响另一组分粒子的隧穿,使得隧穿出现临界现象.

    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.
