自旋为1的玻色-爱因斯坦凝聚体中集体模的透射和反射

Transmission and Reflection of Collective Modes in Spin-1 Bose-Einstein Condensate

Shohei Watabe, Yusuke Kato

摘要:

研究了自旋为1的玻色-爱因斯坦凝聚体中集体激发的隧穿性质。在没有磁场的情况下,除了铁磁态的四极自旋模式外,所有激发态都出现了长波极限的全透射。四极自旋模式单独显示全反射。这些激发之间的差异来自于激发的波函数是否对应于长波长极限下凝聚体的波函数。这种对应关系导致了无自旋BEC中的总透射。

英文摘要:

We study tunneling properties of collective excitations in spin-1 Bose-Einstein condensates. In the absence of magnetic fields, the total transmission in the long wavelength limit occurs in all kinds of excitations but the quadrupolar spin mode in the ferromagnetic state. The quadrupolar spin mode alone shows the total reflection. A difference between those excitations comes from whether the wavefunction of an excitation corresponds to that of the condensate in the long wavelength limit. The correspondence results in the total transmission as in the spinless BEC.
