Bose-Einstein Condensate on a Synthetic Topological Hall Cylinder

Atomic topological quantum matter using synthetic dimensions

“…The use of synthetic dimensions based on internal states also allows for engineering more complex geometries beyond planar ones [39]. Cyclic couplings in the synthetic dimension gives rise to periodic boundary conditions, which has been used to generate quantum Hall systems in a cylindrical geometry [40][41][42][43][44][45][46][47]. In such systems, the absence of edges leads to fully gapped bands characterized by welldefined topological invariants (see fig.…”

Construction of two-dimensional arbitrary shape ⁸⁷Rb atomic array based on spatial light modulator

“…超冷原子作为一个纯净可人为操控的物理系统，为相互作用的量子多体系 统提供了一个理想的研究平台 [1][2][3] ，例如：高温超导 [4][5][6] 、非平衡动力学 [7] 、超流 -莫特绝缘相变 [8][9][10][11] 以及拓扑材料 [12][13][14][15] 等。近年来，随着光晶格和高分辨率成像 技术的引入，冷原子光晶格领域已经发展到构建精确普适量子材料模拟器的研 究阶段。 大多数的光晶格是利用多束激光干涉原理在实空间为冷原子构建一个规则 的周期势，比如三角 [16] 、方形及六角晶格 [17] 、类石墨烯结构晶格 [18] 、扭转双层 光晶格 [19,20] 和自旋依赖的超晶格 [21,22] 等，这些晶格形状依赖多束激光的空间构 型。为了更好地还原和模拟多样化的复杂量子系统，构造适合该体系的特定构 型光晶格就显得尤为重要，比如利用声光偏转器、固定相位片和空间光调制器 等实现任意形状光晶格 [23][24][25][26][27][28][29][30][31] [32] ) 。…”

Strongly interacting Rydberg atoms in synthetic dimensions with a magnetic flux

“…In this paper, we extend the capabilities of Rydberg synthetic dimensions by engineering an internal-state lattice with a tunable artificial gauge field 36 – 41 for small arrays of strongly interacting atoms 42 . We show that the promising results of ref.…”
