Suppressing crosstalk for Rydberg quantum gates
Gina Warttmann, Florian Meinert, Hans Peter Büchler +1
We present a method to suppress crosstalk from implementing controlled-Z gates via local addressing in neutral atom quantum computers. In these systems, a fraction of the laser lig…
Interplay between coherent and dissipative dynamics of bosonic doublons in an optical lattice
M. J. Mark, S. Flannigan, F. Meinert +4
We observe the dissipative dynamics of a dense, strongly interacting gas of bosonic atom pairs in an optical lattice, controlling the strength of the two-body interactions over a w…
Mott-Insulator-Aided Detection of Ultra-Narrow Feshbach Resonances
Manfred J. Mark, Florian Meinert, Katharina Lauber +1
We report on the detection of extremely narrow Feshbach resonances by employing a Mott-insulating state for cesium atoms in a three-dimensional optical lattice. The Mott insulator…
Floquet engineering of correlated tunneling in the Bose-Hubbard model with ultracold atoms
Florian Meinert, Manfred J. Mark, Katharina Lauber +2
We report on the experimental implementation of tunable occupation-dependent tunneling in a Bose-Hubbard system of ultracold atoms via time-periodic modulation of the on-site inter…
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…
Probing the Excitations of a Lieb-Liniger Gas from Weak to Strong Coupling
Florian Meinert, Milosz Panfil, Manfred J. Mark +3
We probe the excitation spectrum of an ultracold one-dimensional Bose gas of Cesium atoms with repulsive contact interaction that we tune from the weakly to the strongly interactin…
Observation of Density-Induced Tunneling
Ole Jürgensen, Florian Meinert, Manfred J. Mark +2
We study the dynamics of bosonic atoms in a tilted one-dimensional optical lattice and report on the first direct observation of density-induced tunneling. We show that the interac…
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…
