(College Park, Md. : APS, 2023)
    Quantum noise imposes a fundamental limitation on the sensitivity of interferometric gravitational-wave detectors like LIGO, manifesting as shot noise and quantum radiation pressure noise. Here, we present the first ...
  • Enhanced shot noise in tunneling through a stack of coupled quantum dots 
    Barthold, P.; Hohls, Frank; Maire, Niels; Pierz, Klaus; Haug, Rolf J. (College Park, MD : American Physical Society, 2006)
    We have investigated the noise properties of the tunneling current through vertically coupled self-assembled InAs quantum dots. We observe super-Poissonian shot noise at low temperatures. For increased temperature this ...
  • Experimental demonstration of reduced tilt-to-length coupling by using imaging systems in precision interferometers 
    Tröbs, M.; Chwalla, M.; Danzmann, K.; Fernández, Barránco, G.; Fitzsimons, E.; Gerberding, O.; Heinzel, G.; Killow, C.J.; Lieser, M.; Perreur-Lloyd, M.; Robertson, D.I.; Schuster, S.; Schwarze, T.S.; Ward, H.; Zwetz, M. (Bellingham : SPIE, 2017)
    Angular misalignment of one of the interfering beams in laser interferometers can couple into the interferometric length measurement and is called tilt-to-length (TTL) coupling in the following. In the noise budget of the ...
  • High-precision cavity spectroscopy using high-frequency squeezed light 
    Junker, J.; Wilken, D.; Huntington, E.; Heurs, Michèle (Washington, DC : The Optical Society, 2021)
    In this article, we present a novel spectroscopy technique that improves the signal-to-shot-noise ratio without the need to increase the laser power. Detrimental effects by technical noise sources are avoided by ...
  • Noise characterization of a single parameter quantized charge pump 
    Hohls, Frank; Maire, Niels; Kaestner, B.; Pierz, Klaus; Schumacher, Hans W.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2009)
    The shot noise of a single parameter quantized charge pump is studied. The pumped current can be varied using a control gate. Quantized current plateaus / = nefp with fp the pumping frequency and e the electron charge are ...
  • Shot-noise at a Fermi-edge singularity: Non-Markovian dynamics 
    Ubbelohde, Niels; Roszak, K.; Hohls, Frank; Maire, Niels; Novotný, T.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2013)
    For an InAs quantum dot we study the current shot noise at a Fermi-edge singularity in low temperature cross-correlation measurements. In the regime of the interaction effect the strong suppression of noise observed at ...
  • Squeezed States of Light for Future Gravitational Wave Detectors at a Wavelength of 1550 nm 
    Meylahn, Fabian; Willke, Benno; Vahlbruch, Henning (College Park, Md. : APS, 2022)
    The generation of strongly squeezed vacuum states of light is a key technology for future ground-based gravitational wave detectors (GWDs) to reach sensitivities beyond their quantum noise limit. For some proposed observatory ...
