Prethermalization Revealed by the Relaxation Dynamics of Full Distribution Functions
David Adu Smith, Michael Gring, Tim Langen +7
We detail the experimental observation of the non-equilibrium many-body phenomenon prethermalization. We study the dynamics of a rapidly and coherently split one-dimensional Bose g…
Absorption Imaging of Ultracold Atoms on Atom Chips
David A. Smith, Simon Aigner, Sebastian Hofferberth +7
Imaging ultracold atomic gases close to surfaces is an important tool for the detailed analysis of experiments carried out using atom chips. We describe the critical factors that n…
A Kapitza-Dirac-Talbot-Lau interferometer for highly polarizable molecules
Stefan Gerlich, Lucia Hackermueller, Klaus Hornberger +8
Research on matter waves is a thriving field of quantum physics and has recently stimulated many investigations with electrons, neutrons, atoms, Bose-condensed ensembles, cold clus…
Multimode dynamics and emergence of a characteristic length-scale in a one-dimensional quantum system
Maximilian Kuhnert, Remi Geiger, Tim Langen +6
We study the non-equilibrium dynamics of a coherently split one-dimensional (1d) Bose gas by measuring the full probability distribution functions of matter-wave interference. Obse…
Relaxation and Pre-thermalization in an Isolated Quantum System
Michael Gring, Maximilian Kuhnert, Tim Langen +7
Understanding relaxation processes is an important unsolved problem in many areas of physics. A key challenge in studying such non-equilibrium dynamics is the scarcity of experimen…
Optical polarizabilities of large molecules measured in near-field interferometry
Lucia Hackermueller, Klaus Hornberger, Stefan Gerlich +3
We discuss a novel application of matter wave interferometry to characterize the scalar optical polarizability of molecules at 532 nm. The interferometer presented here consists of…
Influence of conformational molecular dynamics on matter wave interferometry
Michael Gring, Stefan Gerlich, Sandra Eibenberger +9
We investigate the influence of thermally activated internal molecular dynamics on the phase shifts of matter waves inside a molecule interferometer. While de Broglie physics gener…
Prethermalization in one-dimensional Bose gases: description by a stochastic Ornstein-Uhlenbeck process
Tim Langen, Michael Gring, Maximilian Kuhnert +5
We experimentally study the relaxation dynamics of a coherently split one-dimensional Bose gas using matterwave interference. Measuring the full probability distributions of interf…
