Title: 非马尔可夫多光子手性动力学与巨系统

Abstract: Chiral interactions enable directional control of quantum light, providing new routes for nonreciprocal photon dynamics. While previous studies focused on single photon regimes, this work explores the non-Markovian multiphoton regime in a giant nonlinear system nonlocally coupled to a one-dimensional waveguide, with a tunable phase difference breaking parity symmetry. We show that single-photon transport remains reciprocal, but multiphoton dynamics become chiral, generating direction-dependent higher-order correlations and enabling deterministic creation of multiphoton states with nontrivial statistics from a single input direction, even under strong dissipation. The non-Markovian nature allows tuning of transmitted photon statistics via the coupling-point separation. At a specific phase, internal dynamics become Markovian while output photons retain non-Markovian features. Under strong coherent driving, we uncover nonreciprocal dissipative phase transitions and demonstrate how non-Markovianity shapes the critical response. This framework offers a general strategy for controlling chiral multiphoton dynamics in nonlocally coupled waveguide QED systems. Show Chinese abstract

Abstract: 手性相互作用实现了对量子光的方向控制，为非互易光子动力学提供了新途径。 虽然以前的研究集中在单光子领域，但这项工作探讨了在与一维波导非局部耦合的巨大非线性系统中的非马尔可夫多光子领域，具有可调相位差打破宇称对称性。 我们表明单光子传输仍然是互易的，但多光子动力学变得手性，生成方向依赖的高阶关联，并能够在强耗散下从单一输入方向确定性地创建具有非平凡统计特性的多光子态。 非马尔可夫特性允许通过耦合点间距调节传输光子统计特性。 在特定相位下，内部动力学变为马尔可夫的，而输出光子保留非马尔可夫特征。 在强相干驱动下，我们揭示了非互易耗散相变，并展示了非马尔可夫性如何塑造临界响应。 这一框架为控制非局部耦合波导量子电动力学系统中的手性多光子动力学提供了一种通用策略。
