Atom optics with microfabricated optical elements

Birkl, G.; Buchkremer, F.B.J.; Dumke, R.; Ertmer, Wolfgang (Amsterdam : Elsevier, 2001)

We introduce a new direction in the field of atom optics, atom interferometry, and neutral-atom quantum information processing. It is based on the use of microfabricated optical elements. With these elements versatile and ...
Atominterferometrie im Zeitbereich

Trebst, Tilmann (Hannover : Universität Hannover, 1999)

Characterisation of an experiment for sympathetic cooling and coupling of ions in a cryogenic Penning trap

Meiners, Teresa (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021)

The comparison of the g-factors of the proton and the antiproton is a stringent test of CPT invariance. The state-of-the-art method for the determination of the (anti-)proton's g-factor is the application of the continuous ...
Cryogenic 9Be+ Penning trap for precision measurements with (anti-)protons

Niemann, M.; Meiners, T.; Mielke, J.; Borchert, M.J.; Cornejo, J.M.; Ulmer, S.; Ospelkaus, C. (Bristol : Institute of Physics Publishing, 2019)

Cooling and detection schemes using laser cooling and methods of quantum logic can contribute to high precision CPT symmetry tests in the baryonic sector. This work introduces an experiment to sympathetically cool protons ...
Design and commissioning of an experiment for sympathetic cooling and coupling of ions in a cryogenic Penning trap

Niemann, Malte (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)

Precise comparisons between the properties of matter and antimatter conjugates constitute a stringent test of CPT and Lorentz symmetries. The proton’s and antiproton’s magnetic moments have recently been measured to high ...
Fokussieren und Kühlen neutraler Atome in starken Dipolpotentialen

Schiffer, Markus (Hannover : Universität Hannover, 1997)

Maximizing the capture velocity of molecular magneto-optical traps with Bayesian optimization

Xu, Supeng; Kaebert, Paul; Stepanova, Mariia; Poll, Timo; Siercke, Mirco; Ospelkaus, Silke (Bristol, Bad Honnef : IOP Publishing Ltd., Deutsche Physikalische Gesellschaft, 2021-06)

Magneto-optical trapping (MOT) is a key technique on the route towards ultracold molecular ensembles. However, the realization and optimization of magneto-optical traps with their wide parameter space is particularly ...
Optical loading of a Bose-Einstein condensate

Floegel, Filip (Hannover : Universität, 2003)

Quantum logic inspired techniques for spacetime-symmetry tests with (anti-)protons

Cornejo, Juan M.; Lehnert, Ralf; Niemann, Malte; Mielke, Johannes; Meiners, Teresa; Bautista-Salvador, Amado; Schulte, Marius; Nitzschke, Diana; Borchert, Matthias J.; Hammerer, Klemens; Ulmer, Stefan; Ospelkaus, Christian ([London] : IOP, 2021)

Cosmological observations as well as theoretical approaches to physics beyond the standard model provide strong motivations for experimental tests of fundamental symmetries, such as CPT invariance. In this context, the ...
Study of laser cooling in deep optical lattice: two-level quantum model

Prudnikov, O.N.; Il'enkov, R.Y.; Taichenachev, A.V.; Yudin, V.I.; Rasel, E.M. (Bristol : IOP Publishing LTD, 2018)

We study a possibility of laser cooling of Mg-24 atoms in deep optical lattice formed by intense off-resonant laser field in a presence of cooling field resonant to narrow (3s3s) S-1(0) -> (3s3p) P-3(1) (lambda = 457 nm) ...
Sympathetic cooling schemes for separately trapped ions coupled via image currents

Will, C.; Bohman, M.; Driscoll, T.; Wiesinger, M.; Abbass, F.; Borchert, M.J.; Devlin, J.A.; Erlewein, S.; Fleck, M.; Latacz, B.; Moller, R.; Mooser, A.; Popper, D.; Wursten, E.; Blaum, K.; Matsuda, Y.; Ospelkaus, C.; Quint, W.; Walz, J.; Smorra, C.; Ulmer, S. ([Bad Honnef] : Dt. Physikalische Ges., 2022)

Cooling of particles to mK-temperatures is essential for a variety of experiments with trapped charged particles. However, many species of interest lack suitable electronic transitions for direct laser cooling. We study ...
The TRAPSENSOR facility: An open-ring 7 tesla Penning trap for laser-based precision experiments

Gutiérrez, Manuel J.; Berrocal, Joaquín; Cornejo, Juan M.; Domínguez, Francisco; Del Pozo, Jesús J.; Arrazola, Iñigo; Bañuelos, Javier; Escobedo, Pablo; Kaleja, Oliver; Lamata, Lucas; Rica, Raúl A.; Schmidt, Stefan; Block, Michael; Solano, Enrique; Rodríguez, Daniel (Bristol : Institute of Physics Publishing, 2019)

A Penning-trap facility for high-precision mass spectrometry based on a novel detection method has been built. This method consists in measuring motional frequencies of singly-charged ions trapped in strong magnetic fields ...
Thermometry of 9Be+ ions in a cryogenic Penning trap

Mielke, Johannes (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021)

High precision comparisons of the proton and antiproton g-factor enable stringent tests of CPT symmetry in the baryonic sector. However, current measurement routines suffer from long preparation times and high particle ...

Type-II Zeeman Slower and design and construction of a cryogenic buffer gas beam source

Petzold, Maurice (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)

Ultrakalte Moleküle versprechen neue Einsichten in diversen Forschungsfeldern die von kontrollierter ultrakalter Chemie über Präzisionsmessungen paritätsverletzender Eﬀekte bis hin zu stark korrelierten dipolaren ...
A Zeeman slower for diatomic molecules

Petzold, M.; Kaebert, P.; Gersema, P.; Siercke, M.; Ospelkaus, S. (Bristol : Institute of Physics Publishing, 2018)

We present a novel slowing scheme for beams of laser-coolable diatomic molecules reminiscent of Zeeman slowing of atomic beams. The scheme results in efficient compression of the one-dimensional velocity distribution to ...
