  • Adiabatic spin cooling using high-spin Fermi gases 
    Colomé-Tatché, Maria; Klempt, Carsten; Santos, Luis; Vekua, Teimuraz (Bristol : IOP Publishing Ltd., 2011)
    Spatial entropy redistribution plays a key role in adiabatic cooling of ultra-cold lattice gases. We show that high-spin fermions with a spatially variable quadratic Zeeman coupling may allow for the creation of an inner ...
  • All-optical matter-wave lens using time-averaged potentials 
    Albers, Henning; Corgier, Robin; Herbst, Alexander; Rajagopalan, Ashwin; Schubert, Christian; Vogt, Christian; Woltmann, Marian; Lämmerzahl, Claus; Herrmann, Sven; Charron, Eric; Ertmer, Wofgang; Rasel, Ernst M.; Gaaloul, Naceur; Schlippert, Dennis (London : Springer Nature, 2022)
    The precision of matter-wave sensors benefits from interrogating large-particle-number atomic ensembles at high cycle rates. Quantum-degenerate gases with their low effective temperatures allow for constraining systematic ...
  • Deceleration, precooling, and multi-pass stopping of highly charged ions in Be+ Coulomb crystals 
    Schmöger, L.; Schwarz, M.; Baumann, T.M.; Versolato, O.O.; Piest, B.; Pfeifer, T.; Ullrich, J.; Schmidt, Piet O.; Crespo López-Urrutia, J.R. (College Park, MD : American Institute of Physics, 2015)
    Preparing highly charged ions (HCIs) in a cold and strongly localized state is of particular interest for frequency metrology and tests of possible spatial and temporal variations of the fine structure constant. Our versatile ...
  • Efficient sympathetic motional-ground-state cooling of a molecular ion 
    Wan, Yong; Gebert, Florian; Wolf, Fabian; Schmidt, Piet O. (College Park, MD : American Physical Society, 2015)
    Cold molecular ions are promising candidates in various fields ranging from precision spectroscopy and test of fundamental physics to ultracold chemistry. Control of internal and external degrees of freedom is a prerequisite ...
  • Engineering the sub-Doppler force in magneto-optical traps 
    Xu, S.; Kaebert, P.; Stepanova, M.; Poll, T.; Siercke, M.; Ospelkaus, S. (College Park, MD : APS, 2022)
    Current dual-frequency magneto-optical traps (MOTs) for ultracold molecules are plagued by sub-Doppler heating effects, making them vastly inferior to standard atomic MOTs. Here we demonstrate theoretically that the ...
  • Sympathetic cooling of mixed-species two-ion crystals for precision spectroscopy 
    Wübbena, Jannes B.; Amairi, Sana; Mandel, Olaf; Schmidt, Piet O. (College Park, MD : American Physical Society, 2012)
    Sympathetic cooling of trapped ions has become an indispensable tool for quantum-information processing and precision spectroscopy. In the simplest situation a single Doppler-cooled ion sympathetically cools another ion ...
