In our group we are interested in the physics of many-body quantum systems out of equilibrium. Within this vast field, we look at fundamental, operational and practical questions.

For the fundamental questions, for instance, we study the emergence of phenomena like macroscopic steady states, and what are signatures of chaos in many-body quantum systems. We also spend significant effort on quantum systems in contact with an environment, which gives us the opportunity to study phenomena like glass-like relaxation, current rectification, time crystals, emergence of different phases of matter and measurement induced phase transition.

For the operational questions, we have been implementing and developing numerical methods to study many-body quantum systems, with particular emphasis on tensor networks, exact diagonalization and neural network quantum states, both for closed and open quantum systems. Recently this has led to interesting synergies between quantum inspired algorithms for machine learning, and machine learning algorithms for quantum systems.

Taking a more practical point of view, we look at applications of fundamental research in topics like quantum transport, quantum thermodynamics, energetics of quantum processes, memory of quantum processes and thus quantum computing.

We have collaborated over the years with experimental groups in ultracold atoms, trapped ions, photonics and superconducting qubits.
