  • Hemmerling, Boerge; Gebert, Florian; Wan, Yong; Schmidt, Piet O. (Bristol : IOP Publishing Ltd., 2012)
    Protocols used in quantum information and precision spectroscopy rely on efficient internal quantum state discrimination. With a single ion in a linear Paul trap, we implement a novel detection method which utilizes ...
  • 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 ...
  • Könemann, J.; König, P.; Schmidt, T.; McCann, E.; Fal’ko, V.I.; Haug, Rolf J. (College Park, MD : American Physical Society, 2001)
    Measurements of resonant tunneling through a localized impurity state are used to probe fluctuations in the local density of states of heavily doped GaAs. The measured differential conductance is analyzed in terms of ...
  • Apellaniz, Iagoba; Lücke, Bernd; Peise, Jan; Klempt, Carsten; Toth, Geza (Bristol : IOP Publishing Ltd., 2015-08-13)
    We present a method to verify the metrological usefulness of noisy Dicke states of a particle ensemble with only a few collective measurements, without the need for a direct measurement of the sensitivity. Our method ...
  • Belhadj, Hamza; Hakki, Amer; Robertson, Peter K.J.; Bahnemann, Detlef W. (Cambridge : Royal Society of Chemistry, 2015-08-06)
    The adsorption of water and deuterium oxide on TiO2 surfaces was investigated in the dark as well as under UV(A) irradiation using in situ ATR-FTIR spectroscopy under oxygen and oxygen free conditions. Adsorption of H2O–D2O ...
  • Baumhoff, Peter; Kallweit, Nicole; Kral, Andrej (Amsterdam : Elsevier B.V., 2019)
    Intracochlear optical stimulation has been suggested as an alternative approach to hearing prosthetics in recent years. This study investigated the properties of a near infrared laser (NIR) induced optoacoustic effect. ...
  • Deiss, Markus; Drews, Bjoern; Denschlag, Johannes Hecker; Tiemann, Eberhard (Bristol : IOP Publishing Ltd., 2015-08-10)
    We study the combination of the hyperfine and Zeeman structure in the spin-orbit coupled A(1)Sigma(+)(u) = b(3)Pi(u) complex of Rb-87(2). For this purpose, absorption spectroscopy at a magnetic field around B = 1000 G is ...
  • Rogge, M.C.; Cavaliere, F.; Sassetti, M.; Haug, Rolf J.; Kramer, B. (Bristol : IOP Publishing Ltd., 2006)
    Experimental results for the sequential transport through a lateral quantum dot in a perpendicular magnetic field are compared with theory. Regular patterns of negative differential conductances are observed in the nonlinear ...
  • Kamil, Ahmed M.; Hussein, Falah H.; Halbus, Ahmed F.; Bahnemann, Detlef W. (New York : Hindawi Publishing Corporation, 2014)
    The multiwall carbon nanotubes (MWCNTs)/titanium dioxide (P25) composite in different ratios was prepared using simple evaporation and drying process. The composite was characterized by Raman spectroscopy, X-ray diffraction ...
  • Nair, K. P. Rajappan; Jahn, Michaela K.; Lesarri, Alberto; Ilyushin, Vadim V.; Grabow, Jens-Uwe (Cambridge : Royal Society of Chemistry, 2015-09-22)
    Pure six-fold symmetry (V6) internal rotation poses significant challenges to experimental and theoretical determination, as the very low torsional barriers result in huge tunneling splittings difficult to identify and to ...
  • Lesarri, Alberto; Vega-Toribio, Alicia; Suenram, Richard D.; Brugh, Dale J.; Nori-Shargh, Davood; Boggs, James E.; Grabow, Jens-Uwe (Cambridge : Royal Society of Chemistry, 2011)
    The conformational and structural properties of the inhalational anesthetic isoflurane (1-chloro-2,2,2-trifluoroethyl difluoromethyl ether) have been probed in a supersonic jet expansion using Fourier-transform microwave ...
  • Bracht, Katja; Angrisani, Nina; Seitz, Jan-Marten; Eifler, Rainer; Weizbauer, Andreas; Reifenrath, Janin (London : BioMed Central Ltd., 2015)
    Background: Magnesium alloys are recommended as a potential material for osteosynthesis. It is known that storage-induced property modifications can occur in materials like aluminum. Thus the aim of this study was to analyze ...
  • Lohse, Peter W.; Kuhnt, Julia; Druzhinin, Sergey I.; Scholz, Mirko; Ekimova, Maria; Oekermann, Torsten; Lenzer, Thomas; Oum, Kawon (Cambridge : Royal Society of Chemistry, 2011)
    The relaxation dynamics of the indoline dye D149, a well-known sensitizer for photoelectrochemical solar cells, have been extensively characterized in various organic solvents by combining results from ultrafast ...
