Harnessing the interaction between light and matter is a central topic in quantum optics and emergent quantum technologies. Waveguide-QED (quantum electrodynamics) provides a recent framework in which such interactions, i.e. those between guided photons (particles of light) and elementary quantum emitters (real or artificial atoms), are controlled and engineered through the structure and geometry of the environment in which the two interact. In prior NSF-supported work, the PI has introduced an experimental platform for studies of waveguide-QED effects in the alternative context of ultracold atoms, in which the wells of an optical lattice (i.e. a crystal made of light) act as quantum emitters, while guided atomic matter waves play the role of light. The platform also provides a natural connection to radiatively coupled condensed-matter systems featuring polaritons (quasiparticles made of light and matter). The PI will investigate how tunneling in a lattice influences matter-wave decay, how matter waves reflect from arrays of quantum emitters, and how the controllable properties of quantum emitters can be used to control wave propagation. The project has the potential to address fundamental questions and guide future technological efforts, while also providing pertinent scientific and technical training to graduate and undergraduate students. The project is devoted to studies of coherent radiative behavior in systems of atomic matter-wave quantum emitters. The work uses a recently developed, optical-lattice based platform that provides analogues to waveguide QED and is made possible through the manipulation of coherently coupled hyperfine-state mixtures of bosonic atoms in state-dependent optical lattices. The goals of the project include explorations of super-and subradiant dynamics, of resonant scattering from two- and three-level emitters, and of the effects of polariton bandstructure on matter-wave transport. The project extends the PI's recent NSF-supported work on single-emitter fractional decay, bound states, and the formation of polaritons to address collective dynamical effects, scattering phenomena, and transport behavior.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

利用光与物质之间的相互作用是量子光学和新兴量子技术的核心主题。波导QED（量子电动力学）提供了一个最新的框架，即这种相互作用，即引导光子（光的颗粒）和基本量子发射器（真实或人工原子）之间的相互作用，通过两者相互作用的环境的结构和几何形状进行控制和设计。在先前的NSF支持的工作中，PI引入了一个实验平台，用于在Ultracold Atoms的替代背景下进行波导QED效应研究，其中光学晶格的孔（即用光制成的晶体）用作量子发射器，而Guided Anomic Matter wavered Atomic Matter wave扮演了光的作用。 该平台还提供了与辐射耦合的凝结物系统的自然连接，该系统具有偏振子（由光和物质制成的准粒子）。 PI将研究晶格中的隧道如何影响物质波衰减，物质波如何反映量子发射器的阵列以及如何使用量子发射器的可控性能来控制波浪传播。该项目有可能解决基本问题并指导未来的技术努力，同时还为研究生和本科生提供相关的科学和技术培训。 该项目致力于研究原子物质波量子发射器系统中相干辐射行为。该作品使用了一个最近开发的基于光学晶格的平台，该平台提供了与波导QED的类似物，并通过操纵状态依赖性光学晶格中的骨原子的连贯耦合的高精子混合物而成为可能。该项目的目标包括探索超级和亚基动力学的探索，两级和三级发射器的共振散射以及北极星带结构对Matter-Wave运输的影响。该项目扩展了PI最近在单个发射机分数衰减，约束状态以及北极星的形成方面的工作，以解决集体动力学效果，散射现象和运输行为。该奖项反映了NSF的法定任务，并认为通过基金会的知识优点和广泛的影响，可以通过评估来通过评估来进行评估。
