Physicists have managed to simulate a strange quantum phenomenon where light appears to arise from empty space a concept that ...

The required energy can be determined using quantum electrodynamics (QED), which is the quantum theory of electromagnetism ... principle is based on irradiating the electron’s magnetic field with a ...

In theory, the ultra-narrow spectral linewidth of S-SPR could be realized, ... Scientists have created an ultrashort electron beam with five times more peak current than any other similar beam on ...

Physicists at SLAC National Accelerator Laboratory in the US have shattered the record for most powerful beam of electrons ... the chain of electrons could bunch up and – in theory – pack a greater ...

Researchers found that the transmission efficiency of the photoelectrons was 5%, which in theory has room to improve up to approximately 50%, a promising rate that indicates the material is protected ...

For this reason, such electron beam did not allow neither performing accurate irradiation ... provided that saturation is determined with a different approach (the recombination theory for proton and ...

We present the quantum theory governing the interaction between short laser ... we optimize laser pulses that can reduce the energy spread of an electron beam. We also find attosecond laser pulse ...

Abstract: A 3-D frequency-domain nonlinear theory of the backward wave oscillator (BWO) with an inclined rectangular electron beam (IRB) is presented in this article. The ohmic losses, space-charge ...
