All-Optical Switch and Transistor Gated by One Stored Photon
Wenlan Chen,Kristin M. Beck,Robert Bücker,Robert Bücker,Michael Gullans,Mikhail D. Lukin,Haruka Tanji-Suzuki,Haruka Tanji-Suzuki,Haruka Tanji-Suzuki,Vladan Vuletic +9 more
TL;DR: By stopping a light pulse in an atomic ensemble contained inside an optical resonator, the realization of an all-optical transistor is realized, in which one stored gate photon controls the resonator transmission of subsequently applied source photons.
Integrated Mach–Zehnder interferometer for Bose–Einstein condensates
Tarik Berrada,S. van Frank,Robert Bücker,Thorsten Schumm,Jean-François Schaff,Jörg Schmiedmayer +5 more
TL;DR: A full Mach-Zehnder sequence with trapped Bose-Einstein condensates confined on an atom chip is demonstrated, highlighting the potential of entanglement as a resource for metrology and paving the way for integrated quantum-enhanced matter-wave sensors.
Universal dynamics in an isolated one-dimensional Bose gas far from equilibrium
Sebastian Erne,Sebastian Erne,Sebastian Erne,Robert Bücker,Robert Bücker,Thomas Gasenzer,Jürgen Berges,Jörg Schmiedmayer +7 more
TL;DR: The results establish universal scaling dynamics in an isolated quantum many-body system, which is a crucial step towards characterizing time evolution far from equilibrium in terms of universality classes.
Single-particle-sensitive imaging of freely propagating ultracold atoms
Robert Bücker,Aurélien Perrin,Stephanie Manz,Thomas Betz,Ch. Koller,Thomas Plisson,Joerg Rottmann,Thorsten Schumm,Jörg Schmiedmayer +8 more
TL;DR: In this article, a novel imaging system for ultracold quantum gases in expansion is presented, where atoms fall through a sheet of resonant excitation laser light and the emitted fluorescence photons are imaged onto an amplified CCD camera using a high numerical aperture optical system.

Two-point phase correlations of a one-dimensional bosonic Josephson junction.
Thomas Betz,Stephanie Manz,Robert Bücker,Tarik Berrada,Ch. Koller,Georgy A. Kazakov,Georgy A. Kazakov,Igor Mazets,Igor Mazets,Hans-Peter Stimming,Aurélien Perrin,Aurélien Perrin,Thorsten Schumm,Thorsten Schumm,Jörg Schmiedmayer +14 more
TL;DR: A one-dimensional Josephson junction is realized using quantum degenerate Bose gases in a tunable double well potential on an atom chip to measure the coupling strength and temperature and hence a full characterization of the system.
