Classical and Quantum Fluctuations across Systems and Scales

Fluctuations are a fundamental manifestation of the microscopic stochastic/quantum dynamics of physical systems. They are present at very different scales and give rise to a plethora of effects, relevant across various research fields. Understanding the origin of fluctuation-induced phenomena is rapidly becoming important not only for fundamental investigations but also for the characterization of experimental setups and for the opportunities and challenges that they offer to modern technologies. The seminar covers a broad range of subjects having fluctuations as a common denominator. It focuses on current challenges encompassing diverse physical systems both in and out of equilibrium, spanning different scales and configurations. It is structured around following themes:

• Gravitation: Early Universe Cosmology; physics of black holes; analogue models of gravity.

• Atomic physics & Metrology: Superfluids; ultracold atoms; metrology; sensing.

• Light-matter interaction: Quantum optics; optomechanics; Casimir, Casimir-Polder & van der Waals forces.

• Statistical Physics: Quantum thermodynamics; nonequilibrium physics; complex systems.

The pronounced interdisciplinary nature of the seminar aims to facilitate the exchange of complementary views, methodologies and expertise, fostering cross-fertilization of ideas among diverse research communities. By convening leading experts working on different area of physics directly related to fluctuations, the Seminar provides the ideal setting to assess the current status of this rapidly developing field and to discuss future developments.

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