  • 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 ...

  • Lantz, Kathleen O.; Disterhoft, Patrick; Slusser, James R.; Gao, Wie; Berndt, Jerry L.; Bernhard, Germar; Bloms, Sarah; Booth, Charles Rockwell; Ehramjian, James C.; Harrison, Lee C.; Janson, George T.; Johnston, Paul; Kiedron, Peter W.; McKenzie, Richard L.; Kimlin, Michael G.; Neale, Patrick J.; O'Neill, Michael; Quang, Vi V.; Seckmeyer, Gunther J.; Taylor, Thomas; Wuttke, Sigrid; Michalsky Jr., Joseph J. (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, M.J. (Ljubljana : Society of Mathematicians, Physicists and Astronomers of Slovenia, 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 ...
  • Smorra, Christian; Blessing, Pascal E.; Borchert, Matthias J.; Devlin, Jack A.; Harrington, James A.; Higuchi, Takashi; Morgner, Jonathan; Nagahama, Hiroki; Sellner, Stefan; Bohman, Matthew A.; Mooser, Andreas H.; Schneider, Georg L.; Schön, Natalie; Wiesinger, Markus; Blaum, Klaus; Matsuda, Yasuyuki; Ospelkaus, Christian; Quint, Wolfgang; Walz, Jochen; Yamazaki, Yasunori; Ulmer, Stefan (New York, NY : Springer International Publishing, 2018)
    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 ...

  • 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 ...
  • Comfort, W.W.; Remus, Dieter (Berlin : De Gruyter, 1994)
    Two questions are posed: (a) Which Abelian torsion groups admit a PGT (pseudocompact group topology)? (b) If an Abelian torsion group G admits a PGT, for which cardinal numbers a may such a topology F be chosen so that the ...

  • Jhala, Chirag; Dreissigacker, Ingo; Lein, Manfred (College Park, MD : American Physical Society, 2010)
    Absorbing boundaries in the mean-field approximation are investigated and applied to small systems interacting with strong laser fields. Two types of calculations are considered: (i) a variational approach with a complex ...
  • Steinlechner, Jessica; Ast, Stefan; Krueger, Christoph; Singh, Amrit Pal; Eberle, Tobias; Haendchen, Vitus; Schnabel, Roman (Basel : Mdpi Ag, 2013-01)
    The efficient generation of second-harmonic light and squeezed light requires non-linear crystals that have low absorption at the fundamental and harmonic wavelengths. In this work the photo-thermal self-phase modulation ...
  • Burgess, C.P.; Van Nierop, L.; Parameswaran, Susha L.; Salvio, A.; Williams, M. (Heidelberg : Springer Verlag, 2013)
    We compute how bulk loops renormalize both bulk and brane effective interactions for codimension-two branes in 6D gauged chiral supergravity, as functions of the brane tension and brane-localized flux. We do so by explicitly ...
  • Melchert, O.; Morgner, Uwe; Roth, B.; Babushkin, I.; Demircan, A. (Bellingham, WA : SPIE - International Society for Optical Engineering, 2018)
    We present a numerical approach for the accurate simulation of the complex propagation dynamics of ultrashort optical pulses in nonlinear waveguides, especially valid for few-cycle pulses. The propagation models are derived ...
