Experimental extraction of the quantum effective action for a non-equilibrium many-body system
Maximilian Prüfer, Torsten V. Zache, Philipp Kunkel +5
Far-from-equilibrium situations are ubiquitous in nature. They are responsible for a wealth of phenomena, which are not simple extensions of near-equilibrium properties, ranging fr…

Simultaneous Readout of Noncommuting Collective Spin Observables beyond the Standard Quantum Limit
Philipp Kunkel, Maximilian Prüfer, Stefan Lannig +5
We augment the information extractable from a single absorption image of a spinor Bose-Einstein condensate by coupling to initially empty auxiliary hyperfine states. Performing uni…
