Research group Quantum dynamics and theory of open quantum systems

The group has a long history with interests ranging from entanglement studies in light-matter interacting systems to quantum phase transitions and the dynamics of open quantum systems. Most often, the research delves into fundamental questions, but its relevance is also significant for us, and we frequently discuss with experimentalists. A common theme is to bridge different communities of physics, and an example is our work on quantum simulators. A quantum simulator is a kind of non-universal quantum computer tailored to solve a specific problem that is too challenging to be simulated on a classical computer. Recently, we have focused extensively on open quantum systems. As open systems, these cannot be described by a Hamiltonian, but other means are needed, such as the Lindblad master equation. We have explored critical behavior and dynamics in such systems. Additionally, we are currently interested in the entanglement evolution in open systems.
