TT 18: Focus Session: Relaxation Timescales in Open Quantum Systems (joint session TT/DY)

Monday, March 9, 2026, 15:00–18:00, CHE/0089

In the quantum year 2025 many applications of quantum systems are revisited for their actual physical implementability. Realizing that no quantum system is truly isolated from its environment highlights the need for a thorough understanding of the coupling between an open system and its environment. While many standard treatments lead to Lindblad equations, the underlying approximations are not always applicable and require detailed case-by-case studies. This theoretical focus session provides a platform discussing modern developments in the field in the regime of strongly interacting or driven open systems and their impact on relaxation timescales. We aim to enhance attention and trigger also experimental activity in the field of system-environment interactions and the induced relaxation timescales.
