We investigate spin squeezing of a Bose-Einstein condensate in an open symmetrical double-well trap with dissipation in the tunneling process, which can be treated as a tunneling-dissipative Bose-Hubbard dimer. Perturbation technique based on the system is applied. Its shown that more squeezing can be achieved by increasing the tunneling rate and the dissipation.

隧道耗散 Bose-Hubbard 二聚体中的自旋挤压

我们研究了 Bose-Einstein 凝聚体在隧道过程中耗散的开放对称双阱阱中的自旋挤压，可以将其视为隧道耗散 Bose-Hubbard 二聚体。应用基于该系统的微扰技术。结果表明，通过增加隧穿率和耗散可以实现更多的挤压。
