TT 1: Focus Session: New Routes to Localization and Quantum Non-Ergodicity I (joint session TT/DY)

Monday, March 9, 2026, 09:30–12:15, HSZ/0003

This session explores how quantum many-body systems can fail to thermalize through mechanisms that extend beyond conventional many-body localization. Recent work has discovered new mechanisms that lead to non-ergodic behavior, including Hilbert-space fragmentation, disorder-free localization, and confinement effects that arise from destructive interference in Fock space. At the same time, experiments with ultracold atoms, trapped ions, Rydberg platforms, and superconducting qubits directly reveal many-body scars, slow relaxation, and unusual transport. This session highlights these developments and identifies the central open questions that are now driving the field forward.
