Jeff Harvey said this on Mathoverflow which is a good enough starting point for a CW answer even though I'd be happy about a more detailled response:
String backgrounds determine a CFT, in this CFT there is a state-operator correspondence and the vertex operators used in string scattering computations are given by this correspondence in terms of the ...

Be careful, I believe you confound scattering of light-field (a wave) by particles (wave-atom scattering, the Rayleigh scattering is one of them when the wave-length is well larger than the atom) and the scattering of a particle onto a potential (representing some other particles for instance). The first one is classic, the second one is related to quantum ...

Surface roughness is dependant on the mode of manufacturing. A finish by sandblasting or rolled aluminium sheets differs in
surface roughness
homogenity (long or short periodic defects)
isotropy (production in one line)
abrasion of finishing tool
Regarding the latter the production stability and repeatability of different batches should be kept in mind ...

For a population of identical aerosol particles, the scattering intensity should be approximately proportional to the number concentration of particles. Under two approximations, this is exact. @giacyan's answer points to one approximation: the number concentration of the particles has to be low enough that you can neglect multiple scattering events. If each ...

First of all, the amount of scattered light should be proportional (linearly) to the concentration of aerosol particles, regardless of their size. The dependence may be nonlinear if you put too much particles (the gas becomes opaques). It may also be the property of your light detector - it may be better to measure current instead of voltage.
For large ...
