Scientists have long used Gaussian beams to study how light interacts with matter. These beams resemble plane waves and rely ...

The video also shows an interesting effect due to the wavelength of applied light. The photon energy needed to release an electron depends on the atom it strikes. Neon bulbs have all manner of ...

The study used a photon energy of 1.5 keV ... experimental conditions to achieve specific alignment effects. Understanding electron-cloud alignment dynamics can enhance ultrafast spectroscopy ...

This wave nature produces some interesting effects. For example ... mechanics to mean that a tiny piece of material like a photon or electron is both a particle and a wave. It can be either ...

The photon drag effect is the generation of electrical current ... carrier momentum relaxation time — the time during which an electron can 'remember' the photon momentum, which is very short.

Many next-generation quantum devices rely on single-photon ... centers and electron traps at the interface, but this work presents the first detailed investigation of the effect of these ...

This report both complements and extends Technical Reports Series No. 277/2, Absorbed Dose Determination in Photon and Electron Beams - An International Code of Practice, IAEA Technical Reports Series ...

Experiments coupling light and sound reveal the surprising effect that measuring nothing ... information about the sound wave. Using single-photon detectors, the researchers were able to determine ...
