Indication of critical scaling in time during the relaxation of an open quantum system
Ling-Na Wu, Jens Nettersheim, Julian Feß +6
Phase transitions correspond to the singular behavior of physical systems in response to continuous control parameters like temperature or external fields. Near continuous phase tr…
Power of a quasi-spin quantum Otto engine at negative effective temperature
Jens Nettersheim, Sabrina Burgardt, Quentin Bouton +3
Heat engines usually operate by exchanging heat with thermal baths at different (positive) temperatures. Nonthermal baths may, however, lead to a significant performance boost. We…
Sensitivity of a collisional single-atom spin probe
Jens Nettersheim, Quentin Bouton, Daniel Adam +1
We study the sensitivity of a collisional single-atom probe for ultracold gases. Inelastic spin-exchange collisions map information about the gas temperature T or external magnetic…
