Workshop “Postwar Physics Across Scales” (April 9-10, 2026)
The development of theoretical physics after 1945 has been marked by an increased attempt to both study physical systems “scale by scale” in some independent fashion and build models that could potentially work across all scales. This workshop aims to engage with conceptual aspects of this transformation. In particular, we will give a close look at the set of methods, models, theories, mechanisms and principles that physicists have devised to articulate hierarchies of scales and unify them (e.g., renormalization group methods, effective field theories, symmetry breaking mechanisms, new unifying symmetries).
The detailed program will be available early March 2026.
Workshop on the History and Philosophy of Quantum Field Theory (June 26, 2025)
The workshop is intended to address recent issues in the history and philosophy of quantum field theory at the occasion of Michael Miller’s visit from the University of Toronto (June 23 – June 29, 2025). The event will take place from 9:00 to 18:00.
More information is available here.
