Comment on "Consistent thermostatistics forbids negative absolute temperatures"
Ulrich Schneider, Stephan Mandt, Akos Rapp +4
In this comment we argue that negative absolute temperatures are a well-established concept for systems with bounded spectra. They are not only consistent with thermodynamics, but…

Equilibration rates and negative absolute temperatures for ultracold atoms in optical lattices
Akos Rapp, Stephan Mandt, Achim Rosch
As highly tunable interacting systems, cold atoms in optical lattices are ideal to realize and observe negative absolute temperatures, T < 0. We show theoretically that by reversin…
