Open Quantum Systems: Dissipative Dynamics from Quarks to the Cosmos was a ten-day interdisciplinary program that brought together researchers from nuclear and high-energy physics, condensed matter theory, and quantum information to explore unifying frameworks for dissipative quantum dynamics.
Through a mix of broad overview talks, focused seminars, and extended discussion sessions, participants compared effective field theory and open-system approaches, examined the interplay between Schwinger–Keldysh methods and master equations, and clarified key concepts such as Markovianity, symmetry, and reduced descriptions. A central outcome of the program was the development of a shared conceptual language across traditionally separate communities, laying the groundwork for stronger connections and sustained collaboration in the study of open quantum systems.
