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…

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…
