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…
Accurate measurement of the Sagnac effect for matter waves
Romain Gautier, Mohamed Guessoum, Leonid A. Sidorenkov +3
A rotating interferometer with paths that enclose a physical area exhibits a phase shift proportional to this area and to the rotation rate of the frame. Understanding the origin o…
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…
