My main research interests are nanoscale systems far away from equilibrium and in particular their driven dissipative dynamics. This includes an interest in open (quantum) systems, (quantum) nonlinear dynamics,  topological phenomena and many-body physics. 

In the past I have been investigating nonequilibrium pattern formation like laning and demixing in driven Brownian particles by means of large scale simulations and dynamical density functional theory. When a system is driven out of equilibrium, the formalism of stochastic thermodynamics provides powerful relations like the Jarzynski equality. Generalizing these so called fluctuation theorems to incorporate the measurement device and measurement errors, especially when performing feedback control, has been part of my reserach. 

Furthermore, I explored the interplay of electron transport and mechanical degrees of freedom. In particular, the thermodynamic description of self-oscillation in nano electromechanical systems and their application as stochastic engines and rectifiers. Besides, quantum many-body physics has attracted my attention, especially quantum critical systems and the fate of quantum phase transitions in open system settings as experiments can never be completely isolated. Here, the laws of thermodynamics dictate the way to correctly account for the influence of the environment and leads to a consistent and rigorous framework. Other striking phenomenon of collective behavior in many-body systems that have attracted my attention are superradiance and delocalization. 


Most recently, I have been interested in synchronization of quantum systems. Since the underlying description of the world is quantum, it is natural to ask how classical synchronization phenomena are modified when the degrees of freedom are quantum, and how the principles of synchronization can be stated in a way compatible with quantum mechanics. In particular, I seek to understand how to harness the power of topology known from condensed matter physics for synchronization of quantum systems.
