论文摘要
合成维度对研究多种类型的拓扑，量子和多体物理学产生了极大的兴趣，它们为模拟有趣的物理系统（尤其是在高维度中）提供了灵活的平台。在这封信中，我们描述了一种可编程的光子设备，能够在具有任意拓扑和尺寸的晶格中模仿一类Hamiltonians的动力学。我们在设备的物理学和感兴趣的汉密尔顿人之间得出了对应关系，并模拟了该设备的物理学，以观察各种物理现象，包括霍尔梯子中的手性状态，有效的量规势和高度lattices中的振荡。我们提出的设备为在近期实验平台中研究拓扑和多体物理学开辟了新的可能性。
Synthetic dimensions have generated great interest for studying many types of topological, quantum, and many-body physics, and they offer a flexible platform for simulation of interesting physical systems, especially in high dimensions. In this Letter, we describe a programmable photonic device capable of emulating the dynamics of a broad class of Hamiltonians in lattices with arbitrary topologies and dimensions. We derive a correspondence between the physics of the device and the Hamiltonians of interest, and we simulate the physics of the device to observe a wide variety of physical phenomena, including chiral states in a Hall ladder, effective gauge potentials, and oscillations in high-dimensional lattices. Our proposed device opens new possibilities for studying topological and many-body physics in near-term experimental platforms.
