http://clerkgroup.uchicago.edu/PDFfiles/JModOpt2008.pdf WebWe analyze the performance of optomechanical cooling of a mechanical resonator in the presence of a degenerate optical parametric amplifier within the optomechanical cavity, which squeezes the cavity light. We demonstrate that this allows to significantly enhance the cooling efficiency via the coherent suppression of Stokes scattering. The enhanced …
WebWe present sympathetic cooling in an optomechanical system consisting of two coupled cantilevers. The hybridization of the cantilevers creates a symmetric mode, which is feedback cooled, and an anti-symmetric mode not directly controllable by the feedback. The scheme of sympathetic cooling is adopted to cool the anti-symmetric mode indirectly by … WebDec 22, 2024 · The ground-state cooling of the Brillouin scattering optomechanical system is limited by defects in practical samples. In this paper, we present a compensatory …
WebThis was pioneered by Braginsky and co-workers in their work on optomechanical damping [1,2], while the associated cooling effect was first demonstrated only rather recently [7]. The main ingredient for optomechanical cooling is the appearance of extra damping, ideally without extra fluctuations. This damping is introduced because the light-induced WebMar 6, 2013 · The optomechanical interaction between a mechanical system and an optical field occurs through radiation pressure, a force proportional to the optical field intensity. This can be modeled by a Hamiltonian with and the annihilation operators for photons and phonons in the system.
WebJul 13, 2024 · The process, optomechanical cooling, happens when pressure from photons (particles of light) converts energy stored in the object in the form of thermal phonons (particles of sound) into photons.
WebThe weak force sensing based on a coherent quantum noise cancellation (CQNC) scheme is presented in a hybrid cavity optomechanical system containing a trapped ensemble of ultracold atoms and an optical parametric amplifier (OPA).
