Trapped Matter -Wave Interferometry in Floquet-sculpted band structures
Abstract
Wave interference underlies a variety of important physical phenomena and technologies, ranging from localized electronic states to stealth technologies. Thanks to wave-particle duality, a cornerstone of quantum mechanics, interference phenomena can also be observed and applied in experiments using massive particles. Devices based on the interference of matter waves have long been used as precise sensors of force, acceleration, and rotation. However, traditional spatial matter-wave interferometry techniques based on freely-falling atoms impose fundamental limitations on quantum sensor performance, forcing physics-limited tradeoffs between sensitivity, compactness, bandwidth, and robustness. We propose a program of research aimed at realizing a fundamentally new class of matter-wave interferometer, in which ultracold lithium atoms are continuously trapped in a modulated lattice with a drive-sculpted band structure in order to enable the attainment of new regimes of precision, control, and deployability.
