Physical systems
Research
My main research interests are the nonequilibrium dynamics of quantum field theories, especially their universal properties and phenomenological applications, in particular:
  • Heavy-ion collisions
    • Early-time dynamics, initial stages of the quark-gluon plasma
    • Spectral functions and excitations
    • Transport properties and heavy-quark physics
    • Condensation phenomena

  • Scalar systems out of thermal equilibrium
    • Descriptions of ultra-cold atoms, models of the Early Universe
    • Excitations, Bose-Einstein condensation
    • Universality classes far from equilibrium

  • Complex Langevin equations
Although being apparently very different physical systems, heavy-ion collisions, cold atom experiments and models of the Early Universe share fascinating commonalities.

In my research group, we study them nonperturbatively with classical-statistical lattice simulations and perturbatively using kinetic theories and hard loop calculations, allowing to extract genuinely nonperturbative properties of their dynamics. We have recently also started working on the Complex Langevin method applied to the real-time quantum field description of gauge systems.

My research is partially supported by the FWF under the project "Nonperturbative properties of evolving gluonic plasmas".
