We interpret cooperative scattering by a collection of cold atoms as a multiple-scattering process. Starting from microscopic equations describing the response of N atoms to a probe light beam, we represent the total scattered field as an infinite series of multiple-scattering events. As an application of the method, we obtain analytical expressions of the coherent intensity in the double-scatt...
Structure and dynamics of glassy charged colloids studied with coherent small angle X-ray scattering
Two mechanisms important for the interpretation of radar observations of the atmosphere, are: coherent scattering from refractive index fluctuations of the clear-air and incoherent scattering from particles. These scattering mechanisms have very different wavelength dependencies and their contributions to the radar return can be separated by using two radars with different wavelengths. A differ...
Coherent diffraction microscopy (CDM) is a potential approach to image micromaterials at atomic resolution without crystals. Due the lack of high-angle scattering, achieved limited several nanometers. Small-angle scattering allows researchers reveal high-resolution 3D structures specimens by fitting 1D signals. However, prerequisite models and non-unique solutions restrict general specimens. Un...
