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…
Extracting the symmetries of nonequilibrium quantum many-body systems
Aleksandr N. Mikheev, Viktoria Noel, Ido Siovitz +3
Symmetries play a pivotal role in our understanding of the properties of quantum many-body systems. While there are theorems and a well-established toolbox for systems in thermal e…
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…
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 and non-thermal fixed points in quantum fluids far from equilibrium
Aleksandr N. Mikheev, Ido Siovitz, Thomas Gasenzer
Closed quantum systems far from thermal equilibrium can show universal dynamics near attractor solutions, known as non-thermal fixed points, generically in the form of scaling beha…
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…
