Observation of interspecies Feshbach resonances in an ultracold K-Cs mixture and refinement of interaction potentials
Michael Gröbner, Philipp Weinmann, Emil Kirilov +4
We observe interspecies Feshbach resonances due to s-wave bound states in ultracold K-Cs scattering for three different spin mixtures. The resonances are observed as…
Degenerate Raman sideband cooling of 39K
Michael Gröbner, Philipp Weinmann, Emil Kirilov +1
We report on the first realization of sub-Doppler laser cooling of 39K atoms using degenerate 3D Raman sideband cooling. We take advantage of the well-resolved excited hyperfine st…
A new quantum gas apparatus for ultracold mixtures of K and Cs and KCs ground-state molecules
Michael Gröbner, Philipp Weinmann, Florian Meinert +3
We present a new quantum gas apparatus for ultracold mixtures of K and Cs atoms and ultracold samples of KCs ground-state molecules. We demonstrate the apparatus' capabilities by p…
Observation of many-body long-range tunneling after a quantum quench
Florian Meinert, Manfred J. Mark, Emil Kirilov +5
Quantum tunneling constitutes one of the most fundamental processes in nature. We observe resonantly-enhanced long-range quantum tunneling in one-dimensional Mott-insulating Hubbar…
Interaction-induced quantum phase revivals and evidence for the transition to the quantum chaotic regime in 1D atomic Bloch oscillations
Florian Meinert, Manfred J. Mark, Emil Kirilov +4
We study atomic Bloch oscillations in an ensemble of one-dimensional tilted superfluids in the Bose-Hubbard regime. For large values of the tilt, we observe interaction-induced coh…
Quantum quench in an atomic one-dimensional Ising chain
Florian Meinert, Manfred J. Mark, Emil Kirilov +4
We study non-equilibrium dynamics for an ensemble of tilted one-dimensional atomic Bose-Hubbard chains after a sudden quench to the vicinity of the transition point of the Ising pa…
