Ultracold polar molecules offer strong electric dipole moments and rich internal structure, which makes them ideal building blocks to explore exotic quantum matter, implement novel quantum information schemes more

Marcel Duda sucessfully defended his doctoral thesis on "Production of ground-state 23Na40K molecules in the quantum-degenerate regime" on July 26th, 2022. more

Topology in quantum many-body systems has profoundly changed our understanding of quantum phases of matter. The model that has played an instrumental role in elucidating these effects is the antiferromagnetic spin-1 Haldane chain. more

The Kardar-Parisi-Zhang (KPZ) universality class describes the coarse-grained behavior of a wealth of classical stochastic models. Surprisingly, KPZ universality was recently conjectured to also describe spin transport in the one-dimensional quantum Heisenberg model. more

Ultracold mixtures of bosonic and fermionic atoms provide a powerful platform for studying quantum many-body phenomena. However, the experimental investigation of such mixtures in the strongly interacting regime has been hindered by the three-body recombination loss. more

Exciting ultracold atoms into highly-excited Rydberg states extends the cold atom toolbox by long-range interactions. Rydberg macrodimers - electrostatically bound Rydberg atom pairs - provide bond lengths as large as the distances between different lattice sites in an optical lattice. Optical excitation rates of macrodimers are enhanced if the distance and orientation of the prepared ground state atom pairs match the motional state of the macrodimer state and are suppressed otherwise. more
