    Brillouin-induced Kerr frequency comb in normal dispersion fiber Fabry Perot resonators

    Experimental setup

    Figure 1a depicts the experimental setup. A CW laser with a central wavelength of 1550 nm is used to pump a FFP cavity of 8.75 cm length. This FFP cavity consists of a segment of a single mode normal-dispersion fiber at the…

    Exponentially-enhanced quantum sensing with many-body phase transitions

    Parameter estimation

    In this work, we will be considering single parameter estimation, where the value of an unknown parameter θ is estimated by performing measurements on a quantum state ρ(θ) that encodes the parameter. The quantum state is…

  • Resistance and propulsion performance of a twin skeg ship with different rudder angle

    Resistance and propulsion performance of a twin skeg ship with different rudder angle

    The RBM method is used to numerically simulate the overall scheme of the hull-propeller-rudder interaction. The advantage is that it can simulate the mechanical interaction between the propeller and the hull-rudder with acceptable accuracy. The…

    Photon acceleration of high-intensity vector vortex beams into the extreme ultraviolet

    Photon-accelerated vector vortex beams

    In a photon accelerator, a moving refractive index gradient alters the local phase velocity of a light wave. If the light wave co-travels with a negative (positive) refractive index gradient in a normally…
