Electron-ion coincidence measurements of molecular dynamics with intense X-ray pulses
Scientific Reports, 2021 Molecules can sequentially absorb multiple photons when irradiated by an intense X-ray pulse from a free-electron laser. If the time delay between two photoabsorption events can be determined, this enables pump-probe experiments with a single X-ray pulse,

Известия высших учебных заведений России: Радиоэлектроника, 2021 Introduction. Spectrally efficient frequency division multiplexing (SEFDM) is a promising technology for improving spectral efficiency. Since SEFDM signals transmitted on subcarriers are not orthogonal, interchannel interference occurs due to the mutual ...
