本文报道了利用耗散冷原子实现的宇称-时间（PT）对称非厄米多体系统。在建立了一个PT对称多体系统的理论框架后，我们描述了我们的实验装置，利用单体原子损失作为耗散，特别强调重要系统参数的校准。我们讨论实验观察到的损失动态。
We report our realization of a parity–time (PT)-symmetric non-Hermitian many-body system using cold atoms with dissipation. After developing a theoretical framework on PT-symmetric many-body systems using ultracold atoms in an optical lattice with controlled dissipation, we describe our experimental setup utilizing one-body atom loss as dissipation with special emphasis on calibration of important system parameters. We discuss loss dynamics observed experimentally.
