Experimental Observation of a Generalized Gibbs Ensemble
Tim Langen, Sebastian Erne, Remi Geiger +7
The connection between the non-equilibrium dynamics of isolated quantum many-body systems and statistical mechanics is a fundamental open question. It is generally believed that th…
Degenerate Bose gases with uniform loss
Pjotrs Grišins, Bernhard Rauer, Tim Langen +2
We theoretically investigate a weakly-interacting degenerate Bose gas coupled to an empty Markovian bath. We show that in the universal phononic limit the system evolves towards an…
Towards experimental quantum field tomography with ultracold atoms
A. Steffens, M. Friesdorf, T. Langen +6
The experimental realisation of large scale many-body systems has seen immense progress in recent years, rendering full tomography tools for state identification inefficient, espec…
Chiral Prethermalization in supersonically split condensates
Kartiek Agarwal, Emanuele G. Dalla Torre, Bernhard Rauer +3
We study the dynamics of phase relaxation between a pair of one-dimensional condensates created by a supersonic unzipping of a single condensate. We use the Lorentz invariance of t…
