Webcalculated the optical oscillator strength density of oxygen (7.1–11.2eV) as a function of the energy loss by the coupled-channel method. Additionally, the features of the electron energy-loss spectra at different scattering angles were analyzed in detail in the work of Lewis et al. (2001), which is significant 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). In the proposed system, the back-action noise can be completely eliminated at all frequencies and through the proper …
