Research


Nonequilibrium dynamics provides an unprecedented point of view onto the interacting many-body systems. I am fascinated by that approach because it builds the understanding through surprising connections; via thermalization we can learn a lot about the non-ergodic systems, emergent time-scales can actually give information on the interactions between different subsystems, while some extraordinary properties can be triggered or accessed only by driving. Nonequilibrium as a research topic seems inexhaustible since almost all applications of correlated matter use or rely on nonequilibrium situations. In my past project I addressed questions like: How insulating is a Mott insulator when excited? What properties does pumping induce in a system with approximate conservation laws? Their answers built my intuition on the subject and proliferate ideas for future studies.

Employment


Currently I am a postdoctoral fellow in the group of prof. Achim Rosch at the Institute for Theoretical physics in Cologne. Before that I did my PhD with prof. Peter Prelovšek at the Department of Theoretical Physics, Jožef Stefan Institute.
