Matter wave interferometry in microgravity

Krutzik, Markus

Quantensensoren auf Basis ultra-kalter Atome sind gegenwärtig auf dem Weg ihre klassischen Pendants als Messintrumente sowohl in Präzision als auch in Genauigkeit zu überholen, obwohl ihr Potential noch immer nicht ...

Optical atomic clock aboard an Earth-orbiting space station (OACESS): enhancing searches for physics beyond the standard model in space

Schkolnik, Vladimir; Budker, Dmitry; Fartmann, Oliver; Flambaum, Victor; Hollberg, Leo; Kalaydzhyan, Tigran; Kolkowitz, Shimon; Krutzik, Markus; Ludlow, Andrew; Newbury, Nathan; Pyrlik, Christoph; Sinclair, Laura; Stadnik, Yevgeny; Tietje, Ingmari; Ye, Jun;

We present a concept for a high-precision optical atomic clock (OAC) operating on an Earth-orbiting space station. This pathfinder science mission will compare the space-based OAC with one or more ultra-stable terrestrial ...

Optical clock technologies for global navigation satellite systems

Schuldt, Thilo; Gohlke, Martin; Oswald, Markus; Wüst, Jan; Blomberg, Tim; Döringshoff, Klaus; Bawamia, Ahmad; Wicht, Andreas; Lezius, Matthias; Voss, Kai; Krutzik, Markus; Herrmann, Sven; Kovalchuk, Evgeny; Peters, Achim; Braxmaier, Claus

Future generations of global navigation satellite systems (GNSSs) can benefit from optical technologies. Especially optical clocks could back-up or replace the currently used microwave clocks, having the potential to improve ...

Proposal for space-borne quantum memories for global quantum networking

Gündoğan, Mustafa; Sidhu, Jasminder; Henderson, Victoria; Mazzarella, Luca; Wolters, Janik; Oi, Daniel; Krutzik, Markus

Global-scale quantum communication links will form the backbone of the quantum internet. However, exponential loss in optical fibres precludes any realistic application beyond few hundred kilometres. Quantum repeaters and ...

The Bose-Einstein Condensate and Cold Atom Laboratory

Frye, Kai; Abend, Sven; Bartosch, Wolfgang; Bawamia, Ahmad; Becker, Dennis; Blume, Holger; Braxmaier, Claus; Chiow, Sheng-Wey; Efremov, Maxim A.; Ertmer, Wolfgang; Fierlinger, Peter; Franz, Tobias; Gaaloul, Naceur; Grosse, Jens; Grzeschik, Christoph;

Microgravity eases several constraints limiting experiments with ultracold and condensed atoms on ground. It enables extended times of flight without suspension and eliminates the gravitational sag for trapped atoms. These ...

Time-domain optics for atomic quantum matter

Kanthak, Simon; Gebbe, Martina; Gersemann, Matthias; Abend, Sven; Rasel, Ernst M.; Krutzik, Markus

We investigate time-domain optics for atomic quantum matter. Within a matter-wave analog of the thin-lens formalism, we study optical lenses of different shapes and refractive powers to precisely control the dispersion of ...

Ultracold atom interferometry in space

Lachmann, Maike D.; Ahlers, Holger; Becker, Dennis; Dinkelaker, Aline; Grosse, Jens; Hellmig, Ortwin; Müntinga, Hauke; Schkolnik, Vladimir; Seidel, Stephan T.; Wendrich, Thijs; Wenzlawski, André; Carrick, Benjamin; Gaaloul, Naceur; Lüdtke, Daniel; Braxmaier, Claus;

Bose-Einstein condensates (BECs) in free fall constitute a promising source for space-borne interferometry. Indeed, BECs enjoy a slowly expanding wave function, display a large spatial coherence and can be engineered and ...
