摘要:

非厄米特物理表现出传统厄米特系统之外的独特物理特性,例如对称性破缺、异常点的出现、拓扑相变等。这些现象已在多种平台上被广泛研究,包括量子光学、冷原子系统、超导电路和凝聚态物理。Rydberg原子因其长程相互作用和灵活的可控性,为非厄米特物理的实验实现提供了有前途的平台。本文主要总结了近年来在Rydberg原子系统中非厄米特物理领域的重要实验和理论成果。它概述了非厄米特哈密顿量的基本构造,揭示了由Rydberg原子相互作用引起的有效耗散机制,并讨论了其对能谱特性和对称性破缺的影响。这些研究不仅加深了对非厄米特多体系统量子相变的理解,还突显了Rydberg原子平台在实现和控制拓扑态中的独特价值。

英文摘要:

Non-Hermitian physics exhibits unique physical properties beyond those of traditional Hermitian systems, such as symmetry breaking, the emergence of exceptional points, topological phase transitions, and more. These phenomena have been extensively studied across various platforms, including quantum optics, cold atom systems, superconducting circuits, and condensed matter physics. Rydberg atoms, with their long-range interactions and flexible controllability, provide a promising platform for the experimental realization of non-Hermitian physics. This review primarily summarizes the key experimental and theoretical achievements in the field of non-Hermitian physics within Rydberg atomic systems in recent years. It outlines the fundamental construction of non-Hermitian Hamiltonians, reveals the effective dissipation mechanisms induced by Rydberg atomic interactions, and discusses their impact on spectral properties and symmetry breaking. These studies not only deepen the understanding of quantum phase transitions in non-Hermitian many-body systems but also highlight the unique value of Rydberg atomic platforms in realizing and controlling topological states.
