  • 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 ...
  • Prante, Marc; Ude, Christian; Große, Miriam; Raddatz, Lukas; Krings, Ulrich; John, Gernot; Belkin, Shimshon; Scheper, Thomas (Basel : MDPI AG, 2018)
    Buried explosive material, e.g., landmines, represent a severe issue for human safety all over the world. Most explosives consist of environmentally hazardous chemicals like 2,4,6-trinitrotoluene (TNT), carcinogenic ...
  • Lemeshko, Mikhail; Weimer, Hendrik (London : Nature Publishing Group, 2013)
    The formation of molecules and supramolecular structures results from bonding by conservative forces acting among electrons and nuclei and giving rise to equilibrium configurations defined by minima of the interaction ...
  • Tinne, Nadine; Knoop, Gesche; Kallweit, Nicole; Veith, Sonja; Bleeker, Sebastian; Lubatschowski, Holger; Krüger, Alexander; Ripken, Tammo (Bellingham, WA : SPIE - International Society for Optical Engineering, 2014)
    We present a time-resolved photographic analysis of the pulse-to-pulse interaction. In particular, we studied the influence of the cavitation bubble induced by a fs-pulse on the optical focusing of the consecutive pulse ...
  • Langer, Thomas; Pfnür, Herbert; Tegenkamp, Christoph; Forti, Stiven; Emtsev, Konstantin; Starke, Ulrich (Bristol : IOP Publishing Ltd, 2012-10-29)
    We have investigated the plasmon dispersion in quasi-free-standing monolayer graphene (QFMLG) and epitaxial monolayer graphene (MLG) layers by means of angle resolved electron energy loss spectroscopy. We have shown that ...
  • Ding, Li; Wei, Yanying; Li, Libo; Zhang, Tao; Wang, Haihui; Xue, Jian; Ding, Liang-Xin; Wang, Suqing; Caro, Jürgen; Gogotsi, Yury (London : Nature Publishing Group, 2018)
    Molecular sieving membranes with sufficient and uniform nanochannels that break the permeability-selectivity trade-off are desirable for energy-efficient gas separation, and the arising two-dimensional (2D) materials provide ...
  • Klawunn, M.; Santos, Luis (Bristol : IOP Publishing Ltd., 2009)
    The non-local nonlinearity introduced by the dipole-dipole interaction plays a crucial role in the physics of dipolar Bose-Einstein condensates. In particular, it may distort significantly the stability of straight vortex ...
  • Langer, Thomas; Baringhaus, Jens; Pfnür, Herbert; Schumacher, H.W.; Tegenkamp, Christoph (Bristol : IOP Publishing Ltd., 2010)
    The sheet plasmon in epitaxially grown graphene layers on SiC(0001) and the influence of surface roughness have been investigated in detail by means of low-energy electron diffraction (LEED) and electron energy loss ...
  • Baether, Wolfgang; Zimmermann, Stefan; Gunzer, Frank (Berlin: Walter de Gruyter, 2012-07-26)
    Ion mobility spectrometry is a well-known technique used to analyze trace gases in ambient air. Typically, it works by employing a radioactive source to provide electrons with high energy to ionize the analytes in a series ...
  • Baether, Wolfgang; Zimmermann, Stefan; Gunzer, Frank (Cambridge : Royal Society of Chemistry, 2012)
    Ion mobility spectrometry (IMS) is well known for its very high sensitivity, and thus IMS spectra are commonly used in the identification of trace gases. Extracting quantitative information from IMS spectra is, in contrast, ...
  • Klempt, Carsten; Henninger, T.; Topic, O.; Scherer, M.; Kattner, L.; Tiemann, E.; Ertmer, Wolfgang; Arlt, Jan J. (College Park : American Physical Society, 2008)
    We present a detailed analysis of the production efficiency of weakly bound heteronuclear (40)K(87)Rb Feshbach molecules using radio-frequency association in a harmonic trap. The efficiency was measured in a wide range of ...
  • Grabow, Jens-Uwe; Mata, S.; Alonso, J.L.; Peña, I.; Blanco, S.; López, J.C.; Cabezas, C. (Cambridge : Royal Society of Chemistry, 2011)
    Nicotine has been investigated in the gas phase and two conformational forms were characterized through their rotational spectra. Two spectroscopic techniques have been used to obtain the spectra: a new design of broadband ...
