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…
