  • Achieving ground state and enhancing optomechanical entanglement by recovering information 
    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, ...
  • Hidden symmetries of deformed oscillators 
    Krivonos, Sergey; Lechtenfeld, Olaf; Sorin, Alexander (Amsterdam : Elsevier B.V., 2017)
    We associate with each simple Lie algebra a system of second-order differential equations invariant under a non-compact real form of the corresponding Lie group. In the limit of a contraction to a Schrödinger algebra, these ...
  • Tomographic readout of an opto-mechanical interferometer 
    Kaufer, Henning; Sawadsky, Andreas; Westphal, Tobias; Friedrich, Daniel; Schnabel, Roman (Bristol : IOP Publishing Ltd., 2012-09-12)
    The quantum state of light changes its nature when being reflected off a mechanical oscillator due to the latter's susceptibility to radiation pressure. As a result, a coherent state can transform into a squeezed state and ...
