Observation of sine-Gordon-like solitons in a spinor Bose-Einstein condensate
Yannick Deller, Alexander Schmutz, Raphael Schäfer +7
We experimentally generate sine-Gordon-like solitons in a spin-1 spinor Bose-Einstein condensate (BEC) utilizing a robust and reproducible local phase-imprinting scheme. We find th…
Double sine-Gordon class of universal coarsening dynamics in a spin-1 Bose gas
Ido Siovitz, Anna-Maria E. Glück, Yannick Deller +5
Far from equilibrium, universal dynamics prevails in many different situations, from pattern coarsening to turbulence. A central longstanding problem concerns the development of a…
Entropy estimation in a spin-1 Bose-Einstein condensate
Yannick Deller, Martin Gärttner, Tobias Haas +3
We investigate the information extractable from measurement distributions of two non-commuting spin observables in a multi-well spin-1 Bose-Einstein condensate. We provide a variet…
Area laws and thermalization from classical entropies in a Bose-Einstein condensate
Yannick Deller, Martin Gärttner, Tobias Haas +3
The scaling of local quantum entropies is of utmost interest for characterizing quantum fields, many-body systems, and gravity. Despite their importance, theoretically and experime…
Universal Dynamics at the Lowest Temperatures
Ido Siovitz, Philipp Heinen, Niklas Rasch +5
High-performance graphical processing units (GPU) are used for the repeated parallelised propagation of non-linear partial differential equations on large spatio-temporal grids. Th…
Data-driven discovery of statistically relevant information in quantum simulators
R. Verdel, V. Vitale, R. K. Panda +7
Quantum simulators offer powerful means to investigate strongly correlated quantum matter. However, interpreting measurement outcomes in such systems poses significant challenges.…
Observation of two non-thermal fixed points for the same microscopic symmetry
Stefan Lannig, Maximilian Prüfer, Yannick Deller +5
Close to equilibrium, the underlying symmetries of a system determine its possible universal behavior. Far from equilibrium, however, different universal phenomena associated with…
Universal dynamics of rogue waves in a quenched spinor Bose condensate
Ido Siovitz, Stefan Lannig, Yannick Deller +3
Isolated many-body systems far from equilibrium may exhibit scaling dynamics with universal exponents indicating the proximity of the time-evolution to a non-thermal fixed point. W…
Quantum approximate optimization algorithm for qudit systems
Yannick Deller, Sebastian Schmitt, Maciej Lewenstein +5
A frequent starting point of quantum computation platforms are two-state quantum systems, i.e., qubits. However, in the context of integer optimization problems, relevant to schedu…
