标题： Continuously trapped matter-wave interferometry in magic Floquet-Bloch band structures

摘要： 束缚物质波干涉仪为紧凑型高精度局部力传感提供了前景。 然而，陷阱本身可能会引入传统自由下落干涉仪中不存在的新系统误差。 我们描述并演示了一种新颖的弗洛凯工程平台，用于紧凑的连续束缚原子干涉仪，该平台本质上对陷阱噪声和分束脉冲持续时间具有鲁棒性。 非相互作用的简并量子气体通过幅度调制的光晶格发生位置空间布洛赫振荡，其产生的弗洛凯-布洛赫带结构包含兰道-泽纳分束器和布拉格镜，构成了马赫-曾德尔干涉力传感器的组成部分。 我们识别、实现并实验表征了类似光学晶格钟中使用的魔法波长的魔法带结构，其中干涉相位对晶格强度噪声不敏感。 我们利用弗洛凯合成方法的内在可编程性，展示了各种干涉仪结构，突出了该技术在可调、紧凑、简单且鲁棒的量子力传感器中的潜力。 显示英文摘要

摘要： Trapped matter-wave interferometry offers the promise of compact high-precision local force sensing. However, the trap itself can introduce new systematic errors which are absent in traditional free-fall interferometers. We describe and demonstrate a novel Floquet-engineered platform for compact, continuously trapped atom interferometry which is intrinsically robust against trap noise and beamsplitter pulse duration. A non-interacting degenerate quantum gas undergoes position-space Bloch oscillations through an amplitude-modulated optical lattice, whose resulting Floquet-Bloch band structure includes Landau-Zener beamsplitters and Bragg mirrors, forming the components of a Mach-Zehnder interferometric force sensor. We identify, realize, and experimentally characterize magic band structures, analogous to the magic wavelengths employed in optical lattice clocks, for which the interferometric phase is insensitive to lattice intensity noise. We leverage the intrinsic programmability of the Floquet synthesis approach to demonstrate a variety of interferometer structures, highlighting the potential of this technique for quantum force sensors which are tunable, compact, simple, and robust.
