Curriculum vitae of Volker Karle

Summary

Postdoctoral researcher in driven and hybrid quantum matter (AMO & condensed matter). I study how the non-equilibrium, topological, and entanglement structure of driven and cavity-coupled systems can be harnessed for quantum sensing, quantum materials, and quantum information, combining many-body numerics (ED, Floquet, DMRG/tensor networks) with minimal analytical models and open-source Julia tooling.
