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…
A Maxwell Fish-Eye Lens in a Bose-Einstein Condensate
Jelte Duchêne, Elinor Kath, Floriane Arrouas +7
We experimentally realize an analogue of the optical Maxwell fish-eye lens (MFEL) using phononic excitations in a Bose-Einstein condensate (BEC). A MFEL is characterized by a radia…
Entropy transport in closed quantum many-body systems far from equilibrium
J. Marijan, H. Strobel, M. K. Oberthaler +1
We investigate entropy transport for universal scaling phenomena in closed quantum many-body systems far from equilibrium. From spatially resolved experimental data of a spinor Bos…
Observation of supersolid-like sound modes in a driven quantum gas
Nikolas Liebster, Marius Sparn, Elinor Kath +3
Driven systems are of fundamental scientific interest, as they can exhibit properties that are radically different from the same system at equilibrium. In certain cases, long-lived…
Experimental particle production in time-dependent spacetimes: a one-dimensional scattering problem
Marius Sparn, Elinor Kath, Nikolas Liebster +7
We experimentally study cosmological particle production in a two-dimensional Bose-Einstein condensate, whose density excitations map to an analog cosmology. The expansion of space…
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…
