SYQT: Symposium Quantum Thermalization

SYQT 1: Quantum Thermalization

Mittwoch, 10. September 2025, 10:45–12:45, ZHG104

Why and how do isolated quantum systems thermalize-or fail to do so? This fundamental question lies at the heart of current research in quantum many-body physics. While the eigenstate thermalization hypothesis (ETH) has provided a framework for understanding quantum chaos and ergodicity, a growing class of systems defies this paradigm. Constrained dynamics can lead to rich and exotic behaviors such as Hilbert-space fragmentation, quantum many-body scars, and anomalous transport.

This symposium covers advances in statistical physics, condensed matter, quantum optics, and lattice gauge theories. The talks will highlight both foundational insights and new experimental platforms, including experiments tailored to realize lattice gauge theories and advanced quantum-gas microscopes, complemented by theoretical talks. The theoretical talks will bridge between quantum thermalization in quantum simulators and high-energy physics.
