Tim did his PhD in our Yb hybrid tweezer-lattice experiment. Together with Etienne he started in an empty lab. more

We investigate the quantum many-body dynamics of bosonic atoms hopping in a two-leg ladder with strong on-site contact interactions. We observe that when the atoms are prepared in a staggered pattern with pairs of atoms on every other rung, singlon defects, i.e. rungs with only one atom, can localize due to an emergent topological model, even though the underlying model in the absence of interactions admits only topologically trivial states. more

Using quantum gas microscopes, the wavefunction of a quantum system can be probed with microscopic resolution through projective measurements. By nature of the optical imaging techniques that are used to implement these measurements, the observable that is probed is the local density operator -- each atom in the underlying lattice geometry appears as a bright dot in the recorded image. more

For our group retreat this year, we were staying at the monastery in Oberemarchtal. more

We study nonequilibrium quantum dynamics of spin chains by employing principal component analysis (PCA) on data sets of wave function snapshots and examine how information propagates within these data sets. The quantities we employ are derived from the spectrum of the sample second moment matrix, built directly from data sets. more
