  • Kruse, I.; Lange, K.; Peise, J.; Lücke, Bernd; Pezzè, L.; Arlt, Jan J.; Ertmer, Wolfgang; Lisdat, C.; Santos, Luis; Smerzi, A.; Klempt, Carsten (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    Since the pioneering work of Ramsey, atom interferometers are employed for precision metrology, in particular to measure time and to realize the second. In a classical interferometer, an ensemble of atoms is prepared in ...
  • Nitz, Alexander H.; Capano, Collin; Nielsen, Alex B.; Reyes, Steven; White, Rebecca; Brown, Duncan A.; Krishnan, Badri (Bristol : Institute of Physics Publishing, 2019)
    We present the first Open Gravitational-wave Catalog, obtained by using the public data from Advanced LIGO's first observing run to search for compact-object binary mergers. Our analysis is based on new methods that improve ...
  • Miccoli, Ilio; Edler, Frederik; Pfnür, Herbert; Tegenkamp, Christoph (Bristol : IOP Publishing Ltd., 2015-06-10)
    The electrical conductivity of solid-state matter is a fundamental physical property and can be precisely derived from the resistance measured via the four-point probe technique excluding contributions from parasitic contact ...
  • Steinhauser, Georg; Saey, Paul R. J. (Cham : Springer, 2016)
    The impact of Chernobyl on the 137Cs activities found in wild boars in Europe, even in remote locations from the NPP, has been much greater than the impact of Fukushima on boars in Japan. Although there is great variability ...

(Bellingham Wash. : SPIE, 2008)
    The fifth North American Intercomparison of Ultraviolet Monitoring Spectroradiometers was held June 13 to 21, 2003 at Table Mountain outside of Boulder, Colorado, USA. The main purpose of the Intercomparison was to assess ...
  • Cuntz, Michael Joachim (Ljubljana : DMFA, 2018)
    We present a technique to produce arrangements of lines with nice properties. As an application, we construct (224) and (264) configurations of lines. Thus concerning the existence of geometric (n4) configurations, only ...

    We summarize our recent 1.5 parts per billion measurement of the antiproton magnetic moment using the multi Penning-trap system of the BASE collaboration. The result was achieved by combining the detection of individual ...
  • Heidrich, Marko; Kühnel, Mark P.; Kellner, Manuela; Lorbeer, Raoul-Amadeus; Lange, Tineke; Winkel, Andreas; Stiesch, Meike; Meyer, Heiko; Heisterkamp, Alexander (Washington, DC : Optical Society of America, 2011)
    Biofilms - communities of microorganisms attached to surfaces - are a constant threat for long-term success in modern implantology. The application of laser scanning microscopy (LSM) has increased the knowledge about ...
  • Klempt, Carsten; Henninger, T.; Topic, O.; Will, J.; Ertmer, Wolfgang; Tiemann, E.; Arlt, Jan J. (College Park : American Physical Society, 2007)
    We have observed 28 heteronuclear Feshbach resonances in ten spin combinations of the hyperfine ground states of a 40K−87Rb mixture. The measurements were performed by observing the loss rates from an atomic mixture at ...

  • Khodadadian, Amirreza; Noii, Nima; Parvizi, Maryam; Abbaszadeh, Mostafa; Wick, Thomas; Heitzinger, Clemens (Berlin : Springer, 2020)
    In this work, we propose a parameter estimation framework for fracture propagation problems. The fracture problem is described by a phase-field method. Parameter estimation is realized with a Bayesian approach. Here, the ...
  • Gulbrandsen, Martin G.; Halle, Lars H.; Hulek, Klaus (Berlin : Deutsche Mathematiker-Vereinigung e.V., 2019)
    We present a Geometric Invariant Theory (GIT) con-struction which allows us to construct good projective degenerationsof Hilbert schemes of points for simple degenerations. A comparisonwith the construction of Li and Wu ...
  • Farrelly, Terry (Wien : Verein zur Förderung des Open Access Publizierens in den Quantenwissenschaften, 2020)
    Discretizing spacetime is often a natural step towards modelling physical systems. For quantum systems, if we also demand a strict bound on the speed of information propagation, we get quantum cellular automata (QCAs). ...
  • Zheng, Fei; Zhuang, Xiaoying; Zheng, Hong; Jiao, Yu-Yong; Rabczuk, Timon (Berlin : Springer, 2020)
    Contact interaction of two bodies can be modeled using the penalty function approach while its accuracy and robustness are directly associated with the geometry of contact bodies. Particularly, in the research fields of ...

    We report on the design, construction, and characterization of a 10 m-long high-performance magnetic shield for very long baseline atom interferometry. We achieve residual fields below 4 nT and longitudinal inhomogeneities ...

    Abstract: Gravimetry with low uncertainty and long-term stability opens up new fields of research in geodesy, especially in hydrology and volcanology. The main limitations in the accuracy of current generation cold atom ...
  • Chiodaroli, Elisabetta; Feireisl, Eduard; Kreml, Ondrej; Wiedemann, Emil (Heidelberg : Springer Verlag, 2017)
    Can every measure-valued solution to the compressible Euler equations be approximated by a sequence of weak solutions? We prove that the answer is negative: generalizing a well-known rigidity result of Ball and James to a ...
  • Barrientos, Mauricio A.; Gatica, Gabriel N.; Maischak, Matthias (Cambridge : Cambridge University Press, 2002)
    In this paper we combine the dual-mixed finite element method with a Dirichlet-to-Neumann mapping (given in terms of a boundary integral operator) to solve linear exterior transmission problems in the plane. As a model we ...
