  • 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 ...
  • Gräf, Christian; Barr, B.W.; Bell, A.S.; Campbell, F.; Cumming, A.V.; Danilishin, S.L.; Gordon, N.A.; Hammond, G.D.; Hennig, J.; Houston, E.A.; Huttner, S.H.; Jones, R.A.; Leavey, Sean S.; Lück, Harald; Macarthur, J.; Marwick, M.; Rigby, S.; Schilling, R.; Sorazu, B.; Spencer, A.; Steinlechner, S.; Strain, Kenneth A.; Hild, Stefan (Bristol : IOP Publishing Ltd., 2014-11-07)
    The second generation of large scale interferometric gravitational wave (GW) detectors will be limited by quantum noise over a wide frequency range in their detection band. Further sensitivity improvements for future ...
  • Acernese, F.; Agathos, M.; Aiello, L.; Allocca, A.; Amato, A.; Ansoldi, S.; Antier, S.; Arène, M.; Arnaud, N.; Ascenzi, S.; Astone, P.; Aubin, F.; Virgo Collaboration; Vahlbruch, Henning; Mehmet, Moritz; Lück, Harald; Danzmann, Karsten (College Park, MD : American Physical Society, 2019)
    Current interferometric gravitational-wave detectors are limited by quantum noise over a wide range of their measurement bandwidth. One method to overcome the quantum limit is the injection of squeezed vacuum states of ...
  • Maire, Niels; Hohls, Frank; Lüdtke, T.; Pierz, Klaus; Haug, Rolf J. (College Park, MD : American Physical Society, 2007)
    We present noise measurements of self-assembled InAs quantum dots at high magnetic field. In comparison to I-V characteristics at zero magnetic field, we notice a strong current overshoot that is due to a Fermi-edge ...
  • Neave, David A.; Black, Martin; Riley, Teal R.; Gibson, Sally A.; Ferrier, Graham; Wall, Frances; Broom-Fendley, Sam (Littleton, CO : Society of Economic Geologists, Inc, 2016)
    Rare earth elements (REEs) generate characteristic absorption features in visible to shortwave infrared (VNIRSWIR) reflectance spectra. Neodymium (Nd) has among the most prominent absorption features of the REEs and thus ...
  • Nogueira, Waldo; Buchner, Andreas; Lenarz, Thomas; Edler, Bernd (Heidelberg : SpringerOpen, 2005)
    We describe a new signal processing technique for cochlear implants using a psychoacoustic-masking model. The technique is based on the principle of a so-called "NofM" strategy. These strategies stimulate fewer channels ...
  • Schnabel, Roman; Mavalvala, Nergis; McClelland, David E.; Lam, Ping K. (London : Nature Publishing Group, 2010)
    Einstein's general theory of relativity predicts that accelerating mass distributions produce gravitational radiation, analogous to electromagnetic radiation from accelerating charges. These gravitational waves (GWs) have ...
  • Nauen, A.; Hohls, Frank; Könemann, J.; Haug, Rolf J. (College Park, MD : American Physical Society, 2004)
    We investigate the noise properties of a GaAs/AlxGa 1-xAs resonant-tunneling structure at bias voltages where the current characteristic is determined by single electron tunneling. We discuss the suppression of the shot ...
  • Nauen, A.; Hapke-Wurst, I.; Hohls, Frank; Zeitler, U.; Haug, Rolf J.; Pierz, Klaus (College Park, MD : American Physical Society, 2002)
    We investigate the noise properties of a GaAs-AlAs-GaAs tunneling structure with embedded self-assembled InAs quantum dots in the single-electron tunneling regime. We analyze the dependence of the relative noise amplitude ...
  • Nauen, A.; Hohls, Frank; Maire, Niels; Pierz, Klaus; Haug, Rolf J. (College Park, MD : American Physical Society, 2004)
    We investigate the noise properties of a zero-dimensional InAs quantum dot (QD) embedded in a GaAs-AlAs-GaAs tunneling structure. We observe an approximately linear dependence of the Fano factor and the current as a function ...
  • Chabuda, Krzysztof; Dziarmaga, Jacek; Osborne, Tobias J.; Demkowicz-Dobrzański, Rafał (London : Nature Publishing Group, 2020)
    Identification of the optimal quantum metrological protocols in realistic many particle quantum models is in general a challenge that cannot be efficiently addressed by the state-of-the-art numerical and analytical methods. ...
  • Barke, Simon; Wang, Y.; Delgado, Juan Jose Esteban; Troebs, Michael; Heinzel, Gerhard; Danzmann, Karsten (Bristol : IOP Publishing Ltd., 2015-05-07)
    The most promising concept for low frequency (millihertz to hertz) gravitational wave observatories are laser interferometric detectors in space. It is usually assumed that the noise floor for such a detector is dominated ...
