Hadronic light-by-light scattering contribution to the muon g-2 [PDF]
, 2002 We briefly review the current status of the hadronic light-by-light scattering correction to the muon g-2. Then we present our semi-analytical evaluation of the pion-pole contribution, using a description of the pion-photon-photon form factor based on ...

Atmospheric multiple scattering of fluorescence and Cherenkov light emitted by extensive air showers [PDF]
Nucl.Instrum.Meth.A605:388-398,2009, 2009 Atmospheric scattering of light emitted by an air shower not only attenuates direct fluorescence light from the shower, but also contributes to the observed shower light. So far only direct and singly-scattered Cherenkov photons have been taken into account in routine analyses of the observed optical image of air showers.

Scattering of light in photonic crystals [PDF]
SPIE Proceedings, 2002 A new method is developed to calculate the scattering of light at the surface of a photonic crystal. The problem is solved in terms of virtual surface-current distributions and the calculation takes full advantage of the infinite-space plane-wave expansion method for obtaining the photonic band structure.

Muon Loop Light-by-Light Contribution to Hyperfine Splitting in Muonium [PDF]
Phys. Rev. Lett. 112, 173004 (2014), 2014 Three-loop corrections to hyperfine splitting in muonium generated by the gauge invariant sets of diagrams with muon and tauon loop light-by-light scattering blocks are calculated. These results complete calculations of all light-by-light scattering contributions to hyperfine splitting in muonium.

Path-Length-Resolved Dynamic Light Scattering: Modeling the Transition From Single to Diffusive Scattering [PDF]
, 2000 Dynamic light-scattering spectroscopy is used to study Brownian motion within highly scattering samples. The fluctuations of the light field that is backscattered by a suspension of polystyrene microspheres are measured as power spectra by use of low ...

Superradiant scattering in fluids of light [PDF]
Physical Review D, 2019 We theoretically investigate the scattering process of Bogoliubov excitations on a rotating photon-fluid. Using the language of Noether currents we demonstrate the occurrence of a resonant amplification phenomenon, which reduces to the standard superradiance in the hydrodynamic limit. We make use of a time-domain formulation where superradiance emerges

Dust Scattering In Turbulent Media: Correlation Between The Scattered Light and Dust Column Density [PDF]
, 2013 Radiative transfer models in a spherical, turbulent interstellar medium (ISM) in which the photon source is situated at the center are calculated to investigate the correlation between the scattered light and the dust column density. The medium is modeled using fractional Brownian motion structures that are appropriate for turbulent ISM.

Measurement of Dynamic Light Scattering Intensity in Gels [PDF]
Macromolecules, American Chemical Society, 2014, Macromolecules,
47 (22), pp.6, 2015 In the scientific literature little attention has been given to the use of dynamic light scattering (DLS) as a tool for extracting the thermodynamic information contained in the absolute intensity of light scattered by gels. In this article we show that DLS yields reliable measurements of the intensity of light scattered by the thermodynamic ...

Modelling Surface Light Scattering in the Context of Freeform Optical Design [PDF]
arXiv, 2021 We present a novel approach of modelling surface light scattering in the context of freeform optical design. The model relies on energy conservation and optimal transport theory. For isotropic scattering in cylindrically or rotationally symmetric systems with in-plane scattering, the scattered light distribution can be expressed as a convolution ...
