Watch a 47-minute conference talk from the New Perspectives in Many-body Physics with Quantum Optical Systems conference exploring non-Markovian probes of correlated many-body systems. Delve into cutting-edge experimental platforms for studying quantum interactions between atoms and light, including dense atomic media, nanophotonic interfaces, and quantum electrodynamical circuits coupled to superconducting qubits. Learn about the unique complexities these platforms present, such as engineered light dispersion, reduced system dimensionality, and non-perturbative multiple light scattering. Presented by Archana Kamal from Northwestern University at the Kavli Institute for Theoretical Physics, this talk contributes to a broader discussion on state-of-the-art developments and future challenges in quantum optical systems research.
