Nonlinear Zel'dovich Effect: Parametric Amplification from Medium Rotation.
The interaction of light with rotating media has attracted recent interest for both fundamental and applied studies including rotational Doppler shift measurements. It is also possible to obtain amplification through the scattering of light with orbital angular momentum from a rotating and absorbing cylinder, as proposed by Zel'dovich more than forty years ago. This amplification mechanism has ...
متن کاملExcitation of acoustic beams in layered substrates
2014 A mechanism for the launching of acoustic bulk waves in narrow beams into a solid is discussed. The excitation is at the free surface or on the interface of a layered half-space for which the material of the layer has higher characteristic velocities than those of the substrate material. For a range of layer thickness greater than that corresponding to the cut-off value for the Rayleigh-li...
متن کاملplastic hinge rotation capacity of reinforced concrete beams
a parametric study is performed to assess the influence of the tension reinforcement index, ( ω = ρ fy /f bc), and the bending moment distribution (loading type) on the ultimate deformation characteristics of reinforced concrete (rc) beams. the analytical results for 15 simply supported beams with different amounts of tension reinforcement ratio under three different loading conditions are pres...
متن کاملDirectional "superradiant" collisions: bosonic amplification of atom pairs emitted from an elongated Bose-Einstein condensate.
We study spontaneous directionality in the bosonic amplification of atom pairs emitted from an elongated Bose-Einstein condensate, an effect analogous to superradiant emission of atom-photon pairs. Using a simplified model, we make analytic predictions regarding directional effects for both atom-atom and atom-photon emission. These are confirmed by numerical mean-field simulations, demonstratin...
متن کاملThe onset of matter-wave amplification in a superradiant Bose-Einstein condensate.
The interaction of short and strong laser pulses with an atomic Bose-Einstein condensate is found to generate patterns of recoiling atoms that are different from those seen in previous light-scattering experiments. This phenomenon can only be explained by optical stimulation, showing that the previous description of superradiance as atomic stimulation is incomplete and that matter-wave amplific...
