Research

We aim to understand how complex states arrising from the interplay of spin, orbital, charge, and lattice degrees of freedom can be controlled out of equilibrium. Particular topics are <strong>ultra-fast magnetism</strong>, <strong>photo-induced Mott metal-insulator transtions</strong>, and the <strong>dynamics at correlated surfaces and heterostructures</strong>.

Dynamics of correlated systems

We aim to understand how complex states arrising from the interplay of spin, orbital, charge, and lattice degrees of freedom can be controlled out of equilibrium. Particular topics are ultra-fast magnetism, photo-induced Mott metal-insulator transtions, and the dynamics at correlated surfaces and heterostructures. [more]
We develop numerical methods to describe strongly correlated quantum many-particle systems out of equilibrium, in particular within the context of nonequilibrium dynamical mean-field theory.

How does an isolated system reach thermal equilibrium? Contrary to a naive expectation, the path to thermal equilibrium is not straight, but may be delayed by nonthermal critical behavior or dynamical phase transitions.
