Collective, non-linear dynamics and spontaneous self-organization are abundant in nature, sciences and technology. These processes are found in biology and chemistry, in non-linear optics and condensed matter physics, and across both the classical and the quantum regime. The understanding of such dynamics is important for fundamental sciences, where the non-equilibrium quantum dynamics is a major quest from a fundamental point of view, and for quantum technologies, with the demand for complex systems with robust quantum coherent dynamics.

A promising and versatile platform to study these processes in a highly controlled way is the collective interaction of light with laser-cooled cold or quantum-degenerate matter. This experimental setting explores the innovative control of matter through optomechanical effects, identifying novel quantum phases, investigating light transport in strongly scattering and disordered systems. Additionally, it is advancing our knowledge of long-range coupled systems in the presence of noise and driving fields.

This seminar focuses on collective effects and non-equilibrium quantum dynamics in systems with matter-light interaction. In addition to self-organization of matter in classical and quantized light fields, collective scattering involving coupled dipoles and finite-range interactions, via complex multi-mode light fields or via Rydberg atoms will be central topics in the workshop. The aim is to bring together the different communities working on the crucial topics of this rapidly evolving field. Each topical session is preceded by an introductory talk, followed by several invited and hot-topic talks. The poster and discussion sessions are central elements to the seminar, fostering interaction between junior and senior researchers.

The conference language will be English. The Wilhelm and Else Heraeus-Foundation bears the cost of full-board accommodation for all participants.
