Topic: quantum many-body dynamics

The condensed-matter and quantum-information theory groups seek postdoctoral researchers for autumn 2027, with flexible starting dates. Research spans quantum many-body dynamics, entanglement, correlated materials, topology, superconductivity, quantum optics, ultracold gases, quantum simulation and computation. Successful applicants can join international experimental and theoretical collaborations. Pay follows the German TV-L agreement. Submit supporting materials by 22 November 2026; the advert notes that later applications may also be considered.

Xiehang Yu investigates complexity in quantum many-body dynamics using solvable circuits, tensor networks and non-equilibrium field theory. One direction develops mixed-state deep thermalisation, extending ordinary thermalisation to ensembles of conditional mixed states. Another establishes Lieb–Robinson bounds for non-Markovian open many-body systems and determines the digital-simulation resources needed to reproduce their dynamics.
