论文摘要
我们认为在一维光学晶格中捕获的骨气气体中有强大的两体损失。我们利用多体量子Zeno制度中系统典型的时间尺度的分离来建立与时间依赖性的广义Gibbs集合理论的联系。我们的主要结果是一组简单的速率方程，该方程捕获了相干演化和两体损失的同时作用。这种治疗方法可以准确描述在莫特绝缘状态下制备的气体的动力学，并表明其长期行为与平均场分析显着偏离。还讨论了在亚稳态状态下使用$^{174} $ yb观察我们的预测的可能性。
We consider strong two-body losses in bosonic gases trapped in one-dimensional optical lattices. We exploit the separation of time scales typical of a system in the many-body quantum Zeno regime to establish a connection with the theory of the time-dependent generalized Gibbs ensemble. Our main result is a simple set of rate equations that capture the simultaneous action of coherent evolution and two-body losses. This treatment gives an accurate description of the dynamics of a gas prepared in a Mott insulating state and shows that its long-time behaviour deviates significantly from mean-field analyses. The possibility of observing our predictions in an experiment with $^{174}$Yb in a metastable state is also discussed.
