  • Miao, Haixing; Danilishin, Stefan L.; Mueller-Ebhardt, Helge; Chen, Yanbei (Bristol : IOP Publishing Ltd., 2010)
    For cavity-assisted optomechanical cooling experiments, in order to achieve the quantum ground state of the mechanical oscillator, the cavity bandwidth needs to be smaller than the mechanical frequency. In the literature, ...
  • Xuereb, Andre; Usami, Koji; Naesby, Andreas; Polzik, Eugene S.; Hammerer, Klemens (Bristol : IOP Publishing Ltd., 2012-08-29)
    Cooling of the mechanical motion of a GaAs nano-membrane using the photothermal effect mediated by excitons was recently demonstrated by some of the authors (Usami et al 2012 Nature Phys. 8 168) and provides a clear example ...
  • Vogell, B.; Kampschulte, T.; Rakher, M.T.; Faber, A.; Treutlein, P.; Hammerer, Klemens; Zoller, P. (Bristol : IOP Publishing Ltd., 2015-04-22)
    We propose and investigate a hybrid optomechanical system consisting of a micro-mechanical oscillator coupled to the internal states of a distant ensemble of atoms. The interaction between the systems is mediated by a light ...
  • Kaltenbaek, Rainer; Aspelmeyer, Markus; Barker, Peter F.; Bassi, Angelo; Bateman, James; Bongs, Kai; Bose, Sougato; Braxmaier, Claus; Brukner, Caslav; Christophe, Bruno; Chwalla, Michael; Cohadon, Pierre-Francois; Cruise, Adrian Michael; Curceanu, Catalin (Heidelberg : SpringerOpen, 2016)
    Do the laws of quantum physics still hold for macroscopic objects - this is at the heart of Schrodinger's cat paradox - or do gravitation or yet unknown effects set a limit for massive particles? What is the fundamental ...
  • Aufmuth, Peter; Danzmann, Karsten; Hage, B.; Kwee, P.; Lueck, H.; Meier, Tobias; Thuering, A.; Willke, Benno; et al. (Bristol : IOP Publishing Ltd., 2009)
    We introduce a novel cooling technique capable of approaching the quantum ground state of a kilogram-scale system-an interferometric gravitational wave detector. The detectors of the Laser Interferometer Gravitational-wave ...
  • Freise, A.; Bunkowski, A.; Schnabel, R. (Bristol : IOP Publishing Ltd., 2007)
    Diffraction gratings have been proposed as core optical elements in future laser interferometric gravitational-wave detectors. In this paper, we derive equations for the coupling between alignment noise and phase noise at ...
  • Vahlbruch, H.; Chelkowski, S.; Danzmann, Karsten; Schnabel, R. (Bristol : IOP Publishing Ltd., 2007)
    We report the experimental realization of squeezed quantum states of light, tailored for new applications in quantum communication and metrology. Squeezed states in a broad Fourier frequency band down to 1 Hz have been ...
  • Larson, Jonas; Fernandez-Vidal, Sonia; Morigi, Giovanna; Lewenstein, Maciej (Bristol : IOP Publishing Ltd., 2008)
    We investigate a paradigm example of cavity quantum electrodynamics with many body systems: an ultracold atomic gas inside a pumped optical resonator, confined by the mechanical potential emerging from the cavity-field ...
