Localized magnetic moments with tunable spin exchange in a gas of ultracold fermions
Luis Riegger, Nelson Darkwah Oppong, Moritz Höfer +3
We report on the experimental realization of a state-dependent lattice for a two-orbital fermionic quantum gas with strong interorbital spin exchange. In our state-dependent lattic…
Direct probing of the Mott crossover in the SU() Fermi-Hubbard model
Christian Hofrichter, Luis Riegger, Francesco Scazza +4
The Fermi-Hubbard model (FHM) is a cornerstone of modern condensed matter theory. Developed for interacting electrons in solids, which typically exhibit SU() symmetry, it descri…
Observation of an orbital interaction-induced Feshbach resonance in 173-Yb
M. Höfer, L. Riegger, F. Scazza +6
We report on the experimental observation of a novel inter-orbital Feshbach resonance in ultracold 173-Yb atoms, which opens the possibility of tuning the interactions between the…
Observation of scaling in the dynamics of a strongly quenched quantum gas
Eike Nicklas, Markus Karl, Moritz Höfer +6
We report on the experimental observation of scaling in the time evolution following a sudden quench into the vicinity of a quantum critical point. The experimental system, a two-c…
Observation of two-orbital spin-exchange interactions with ultracold SU(N)-symmetric fermions
F. Scazza, C. Hofrichter, M. Höfer +3
We report on the direct observation of spin-exchanging interactions in a two-orbital SU(N)-symmetric quantum gas of ytterbium in an optical lattice. The two orbital states are repr…
