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.[1] Wu B, Niu Q 2000 Phys. Rev. A 61 023402
