摘要：

激光的互连在从产生高功率激光到研究非平衡耦合系统等多个研究领域中至关重要。本文探讨了我们对阵列中激光器之间厄米耦合的研究，旨在实现任意耦合并产生能够打破时间反演对称性的人工规范场。为此，我们研究了三种激光阵列几何结构内的厄米耦合：100个激光器的方形阵列、130个激光器的三角形阵列和8个激光器的环形阵列。在方形阵列中，我们以$2π/120$弧度的精度实现了任意激光耦合，从而能够实现任何所需的相位锁定状态。在三角形阵列中，我们以99%的纯度控制了激光器的手性。在环形阵列中，人工规范场的引入揭示了不同拓扑相位锁定状态之间离散的量化一阶相变。这种对强度和相位均可控制的任意耦合，为探索以奇异、非常规耦合为特征的自旋系统和配置铺平了道路。

英文摘要：

The interconnection of lasers is pivotal across various research domains, from generating high-power lasers to studying out-of-equilibrium coupled systems. This paper explores our investigation into Hermitian coupling between lasers in an array, with the aim of achieving arbitrary coupling and creating artificial gauge fields that can break time-reversal symmetry. For that, we investigated Hermitian coupling within three laser array geometries: a square array of 100 lasers, a triangular array of 130 lasers, and a ring array of 8 lasers. In the square array, we implemented arbitrary laser coupling with a precision of $2π/120$ radians, enabling the attainment of any desired phase-locking state. In the triangular array, we controlled the chirality of the lasers with 99% purity. In the ring array, the introduction of an artificial gauge field revealed discrete quantized first-order transitions between distinct topological phase-locking states. This arbitrary coupling, with control over both the strength and phase, paves the way for exploring spin systems and configurations characterized by exotic, non-conventional coupling.
