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 and renormalization group methods, effective field theories, thermal field theories, grand unified theories, symmetry breaking mechanisms, new unifying symmetries, new approximation methods).
