Abstract We study the sensitivity of possible CLIC and FCC-ee measurements light-by-light scattering to old new physics, including Heisenberg–Euler Lagrangian in Standard Model with contributions from loops additional charged particles or magnetic monopoles, Born–Infeld extension QED, effective dimension-8 operators involving four electromagnetic field strengths as could appear Effective Field ...

We report focusing of coherent light through opaque scattering materials, by control of the incident wavefront. The multiply scattered light forms a focus that is up to a factor 1000 brighter than the normal diffuse transmission. [This chapter has been published as: I. M. Vellekoop and A. P. Mosk, Opt. Lett. 32, 2309–2311 (2007)] Random scattering of light is what makes materials such as white ...

Angularly resolved light scattering measurements made at visible wavelengths have the ability to quantify subcellular morphology, with particular sensitivity to organelles the size of mitochondria and lysosomes. We have recently reported on a lysosome-staining-based method that provides scattering contrast between stained and unstained cells, and through the use of appropriate models, we extrac...

The angular distribution of forward-scattered light in transient-scattering-mode (TSM) and extended-scattering-mode (ESM) ferroelectric liquid-crystal (FLC) devices was evaluated by use of circularly polarized incident light. For both modes the intensity and the distribution of forward-scattered light depended primarily on the FLC birefringence, spontaneous polarization, and the cell path lengt...

To ascertain a direct relationship between the light scattering intensity and the particle scattering the light, thin (6-20 micrometers) sections were cut from frozen human cataracts. Freezing for 15 min (-10 C) and then thawing had no effect on the clarity or light scattering properties of nuclear cataracts. Cortical cataracts treated in the same manner appeared to be much clearer than they we...

The (( Intermediate scattering function )t I(K, t ) of light scattered by motile bacteria is shown to be I(K, t ) = rn sin KVt jo T v T Ps(V) dV, (1) where Ps(V) is the distribution of swimming speeds of the bacteria. ~cattercd spectra from motile E, Coli Klz bacteria have been investigated by laser light intensity correlation spectroscopy. [Z(K, t ) ] z is obtained from the data and its angula...
