Our research
We prepare ultracold atoms and molecules in optical lattices and tweezer arrays, control their interactions and image them with single-atom resolution. The aim is to understand strongly correlated quantum matter and the interaction of light with ordered atomic systems.
Four research themes.
Eight experiments at MPQ and LMU.

Optical clock qubits for the Munich Quantum Valley quantum computing demonstrator.
Dipolar quantum matter
Ultracold polar molecules with long-range dipolar interactions.
Quantum optics / Quantum many-body physics
Subwavelength atomic arrays, Rydberg interactions and non-equilibrium dynamics.
Quantum many-body physics
Bosonic flux ladders, lattice gauge theories and quantum dynamics.
Quantum simulation & computing
Programmable interactions in ordered atomic arrays.
Quantum simulation & computing
A fermionic quantum processor for analogue and digital operation.
01 / Quantum many-body physics
We study how collective behaviour emerges from the interactions between individual particles. Quantum gas microscopes resolve single atoms in optical lattices and give direct access to spin and charge correlations in Hubbard models.

02 / Quantum simulation & computing
Well-controlled atomic systems can address many-body problems that are hard to solve on classical computers. We develop platforms that combine analogue quantum simulation with digital, gate-based quantum computing.
In a hybrid cycle, digital gates prepare the input state, the atoms evolve under the Fermi-Hubbard Hamiltonian, and a basis change before readout gives access to energies and currents, spin and charge correlations, and pair correlations.

03 / Quantum optics
Atoms arranged with a spacing below the optical wavelength scatter light collectively. We study how this changes the optical response of the array, from a subradiant atomic mirror to an array switched by a single Rydberg atom.

04 / Dipolar quantum matter
Ultracold polar molecules bring strong, long-range and anisotropic interactions to quantum gases. In optical lattices they offer routes to spin models and extended Hubbard models with interactions beyond nearest neighbours.
