Bose polarons as relativistic Unruh-DeWitt detectors: Entanglement harvesting from Bose-Einstein condensates
T. Rick Perche, Francesco Gozzini, Markus K. Oberthaler
We show that a bound impurity in a Bose-Einstein condensate can be directly mapped to an Unruh-DeWitt detector interacting with a relativistic quantum field. We provide explicit ex…
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…
