Independent Research Groups

The group Atomic Quantum Matter pursues the experimental application of quantum information concepts to ultracold atomic systems. We use the tools of quantum gas microscopy, including optical tweezers, lattices, and single-particle resolved imaging, to realize many-body systems with single-particle control. Our experiments provide the experimental testbed for new ideas emerging at the interface between condensed matter physics and quantum information science. more

The independent research group Quantum Matter Interfaces aims to study the connection of assembled arrays of laser-cooled atoms to novel interfaces with optical photons. Therefore, we combine atomic Rydberg arrays in optical tweezers with optical resonators. Next to the realization of measurement-based controlled feedback on quantum systems – the basis of quantum error correction – our aim is also to study novel interactions and the generation of entanglement in quantum many-body systems. more

Often discrepancies between theory and experiment led to advancements in physics. This is also how quantum electrodynamics, or QED in short, emerged. Today, it is the most precise theory in physics and served as a blueprint for all subsequent field theories. However, as is known from cosmological observations, unknown physics beyond the so-called standard model must exist. It probably lies hidden where no one has been looking, e.g. at very high energies or extreme precision. more

The ultracold lithium-rubidium project will explore the rich phase diagram of a degenerate Fermi gas of polar molecules near a field-linked scattering resonance, including the long-sought dipolar p-wave superfluid of fermionic diatomic molecules, the Bose-Einstein condensate (BEC) of tetermer molecules, and the crossover/transition in between. more

The new independent research group “Dynamical Quantum Matter Theory” is an interdisciplinary group that focuses on quantum simulation and computing, as well as quantum many-body dynamics and far-from-equilibrium statistical mechanics. Intersecting quantum many-body and high-energy physics, the work of the group involves a strong numerical element using tensor networks and exact diagonalization. more
