SYFC: Symposium Designing Quantum Materials with Light: From Floquet to Cavity Engineering

SYFC 1: Designing Quantum Materials With Light: from Floquet to Cavity Engineering

Monday, March 9, 2026, 09:30–12:15, HSZ/AUDI

This symposium focuses on how tailored light fields and optical cavities can be used to design and control novel phases of quantum matter far from thermal equilibrium or even in the dark. Building on rapid progress in ultrafast experiments – including time-resolved momentum microscopy and high-quality 2D/3D materials – Floquet and cavity engineering now enable the creation of engineered band structures, correlated and topological phases, and emergent “polaritonic quantum matter.” In parallel, ab initio and advanced many-body theory have matured to the point of providing quantitative guidance and interpretation for these experiments. The symposium will bring together leading international experts from theory and experiment to discuss current breakthroughs and future directions towards optoelectronic and quantum-information devices based on light-designed quantum materials.
