  • Characterisation of GNSS carrier phase data on a moving zero-baseline in urban and aerial navigation 
    Ruwisch, Fabian; Jain, Ankit; Schön, Steffen (Basel : MDPI AG, 2020)
    We present analyses of Global Navigation Satellite System (GNSS) carrier phase observations in multiple kinematic scenarios for different receiver types. Multi-GNSS observations are recorded on high sensitivity and ...
  • Comparative in vitro study and biomechanical testing of two different magnesium alloys 
    Weizbauer, Andreas; Modrejewski, Christian; Behrens, Sabine; Klein, Helmut; Helmecke, Patrick; Seitz, Jan-Marten; Windhagen, Henning; Möhwald, Kai; Reifenrath, Janin; Waizy, Hazibullah (London : SAGE Publications Ltd., 2014)
    In this in vitro study, magnesium plates of ZEK100 and MgCa0.8 alloy similar to common titanium alloy osteosynthesis plates were investigated as degradable biomedical materials with a focus on primary stability. Immersion ...
  • Conformational steering in dicarboxy acids: the native structure of succinic acid 
    Jahn, Michaela K.; Mendez, Estibaliz; Nair, K. P. Rajappan; Godfrey, Peter D.; McNaughton, Don; Ecija, Patricia; Basterretxea, Francisco J.; Cocinero, Emilio J.; Grabow, Jens-Uwe (Cambridge : Royal Society of Chemistry, 2015-03-13)
    Succinic acid, a dicarboxylic acid molecule, has been investigated spectroscopically with computational support to elucidate the complex aspects of its conformational composition. Due to the torsional freedom of the carbon ...
  • Method Comparison for Simulating Non-Gaussian Beams and Diffraction for Precision Interferometry 
    Zhao, Mengyuan; Tao, Yazheng; Weber, Kevin; Kaune, Tim; Schuster, Sönke; Hao, Zhenxiang; Wanner, Gudrun (Basel : MDPI, 2023)
    In the context of simulating precision laser interferometers, we use several examples to compare two wavefront decomposition methods—the Mode Expansion Method (MEM) and the Gaussian Beam Decomposition (GBD) method—for their ...
  • A representation-free description of the Kasevich-Chu interferometer: a resolution of the redshift controversy 
    Schleich, Wolfgang P.; Greenberger, Daniel M.; Rasel, Ernst Maria (Bristol : IOP Publishing Ltd., 2013-01-07)
    Motivated by a recent claim by Muller et al (2010 Nature 463 926-9) that an atom interferometer can serve as an atom clock to measure the gravitational redshift with an unprecedented accuracy, we provide a representation-free ...
  • Two-Color Grating Magneto-Optical Trap for Narrow-Line Laser Cooling 
    Bondza, S.; Lisdat, C.; Kroker, S.; Leopold, T. (College Park, Md. [u.a.] : American Physical Society, 2022)
    We demonstrate the two-color cooling and trapping of alkaline-earth atoms in a grating magneto-optical trap (GMOT). The trap is formed by a single incident laser beam together with four secondary beams that are generated ...
  • Universal atom interferometer simulation of elastic scattering processes 
    Fitzek, Florian; Siemß, Jan-Niclas; Seckmeyer, Stefan; Ahlers, Holger; Rasel, Ernst M.; Hammerer, Klemens; Gaaloul, Naceur (London : Nature Publishing Group, 2020)
    In this article, we introduce a universal simulation framework covering all regimes of matter-wave light-pulse elastic scattering. Applied to atom interferometry as a study case, this simulator solves the atom-light ...
