Simple Method of Light Field Calculation for Shaping of 3D Light Curves

open access: yesPhotonics, 2023
We propose a method for generating three-dimensional light fields with given intensity and phase distributions using purely phase transmission functions.

Six-dimensional light-front Wigner distributions of the proton

open access: yesEuropean Physical Journal C: Particles and Fields
We investigate six-dimensional quark Wigner distributions of the proton in a light-front quark spectator-diquark model. Benefiting from the light-front boost-invariant longitudinal variable $$\tilde{z}$$ z ~ , these light-front Wigner distributions ...

Gluon Wigner distributions in a light-cone spectator model

open access: yesEuropean Physical Journal C: Particles and Fields
We study the gluon Wigner distributions of the proton which are the phase-space distributions containing the most general one-parton information. Using the proton wave functions deduced from a light-cone spectator model that contains the gluonic degree ...

The Spectral Distribution of Firefly Light [PDF]

open access: yesThe Journal of General Physiology, 1964
The in vivo emission spectra of sixteen species of Jamaican fireflies and four species of American fireflies have been measured with a photoelectric recording spectrometer. A simple technique of stimulation with ethyl acetate vapor was found to elicit bright continuous emission over a period of several minutes.

Parton distributions of light quarks and antiquarks in the proton

open access: yesPhysics Letters B, 2022
An algebraic Ansatz for the proton's Poincaré-covariant wave function, which includes both scalar and pseudovector diquark correlations, is used to calculate proton valence, sea, and glue distribution functions (DFs).

Estimation of pollen counts from light scattering intensity when sampling multiple pollen taxa – establishment of an automated multi-taxa pollen counting estimation system (AME system) [PDF]

open access: yesAtmospheric Measurement Techniques, 2021
Laser optics have long been used in pollen counting systems. To clarify the limitations and potential new applications of laser optics for automatic pollen counting and discrimination, we determined the light scattering patterns of various pollen types ...

Simplifying the calculation of light scattering properties for black carbon fractal aggregates [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
Black carbon fractal aggregates have complicated shapes that make the calculation of their optical properties particularly computationally expensive. Here, a method is presented to estimate fractal aggregate light scattering properties

Discrete Entanglement Distribution with Squeezed Light [PDF]

open access: yesPhysical Review Letters, 2004
We show how one can entangle distant atoms by using squeezed light. Entanglement is obtained in steady state, and can be increased by manipulating the atoms locally. We study the effects of imperfections, and show how to scale up the scheme to build a quantum network.

Light-front holographic ρ-meson distributions in the momentum space

open access: yesJournal of High Energy Physics, 2021
We present the leading-twist quark transverse momentum-dependent parton distribution functions (TMDs) for the spin-1 target, such as the ρ-meson, in the light-front framework.
