Shapiro steps in driven atomic Josephson junctions
Vijay Pal Singh, Juan Polo, Ludwig Mathey +1
We study driven atomic Josephson junctions realized by coupling two two-dimensional atomic clouds with a tunneling barrier. By moving the barrier at a constant velocity, dc and ac…
Quantum Gate Optimization for Rydberg Architectures in the Weak-Coupling Limit
Nicolas Heimann, Lukas Broers, Nejira Pintul +5
We demonstrate machine learning assisted design of a two-qubit gate in a Rydberg tweezer system. Two low-energy hyperfine states in each of the atoms represent the logical qubit an…
Quantum rotation sensor with real-time readout based on an atom-cavity system
Jim Skulte, Jayson G. Cosme, Ludwig Mathey
Using an atom-cavity platform, we propose to combine the effective gauge phase of rotated neutral atoms and the superradiant phase transition to build a highly sensitive and fast q…
Thermal suppression of demixing dynamics in a binary condensate
Vijay Pal Singh, Luigi Amico, Ludwig Mathey
We investigate the demixing dynamics in a binary two-dimensional (2D) Bose superfluid using classical-field dynamics. By quenching the interspecies interaction parameter, we identi…
Bridging closed and dissipative discrete time crystals in spin systems with infinite-range interactions
Jayson G. Cosme, Jim Skulte, Ludwig Mathey
We elucidate the role that the dissipation in a bosonic channel plays in the prevalence and stability of time crystals (TCs) in a periodically driven spin-boson system described by…
Predicting the motion of a high-Q pendulum subject to seismic perturbations using machine learning
Nicolas Heimann, Jan Petermann, Daniel Hartwig +2
The seismically excited motion of high-Q pendula in gravitational-wave observatories sets a sensitivity limit to sub-audio gravitational-wave frequencies. Here, we report on the us…
