Title: Simulating Waveguide Quantum Electrodynamics with Atomic Matter Waves
Speaker: Dominik Schneble. (Department of Physics & Astronomy, Stony Brook University, NY, USA)

Abstract: Understanding and harnessing light-matter interactions in novel contexts is central to the development of modern quantum technologies. One example is the emerging field of waveguide quantum electrodynamics (wQED) which investigates the coherent coupling between one or more quantum emitters and an engineered low-dimensional photonic bath. While recent wQED experiments have observed modified spontaneous emission, bound-state mediated interactions, and superradiance, a clean access to the underlying mechanisms often remains challenging. We approach wQED with an unconventional platform in which artificial quantum emitters, realized with ultracold atoms in an optical lattice, undergo spontaneous radiative decay by emitting single atoms, rather than single photons. I will introduce the unique aspects of our matter-wave platform  and present some recent work on simulating radiative many-body effects at the boundary between atomic physics, quantum optics, and condensed-matter physics.

Speaker: Dominik Schneble is a professor in the Department of Physics and Astronomy at Stony Brook University. His group focuses on experimental studies with ultracold atomic quantum gases to address questions across different fields of physics through quantum simulations. He received his doctorate from the University of Konstanz, Germany, in 2002 for work in the field of atom optics. He joined Stony Brook University in 2005 after conducting postdoctoral research with Wolfgang Ketterle at the MIT-Harvard Center for Ultracold Atoms at MIT. In 2020, he was elected Fellow of the American Physical Society.
