Physicists have proposed a way to extract the internal quantum states of electron wave packets by analyzing how those packets ...

Quantum theory explains the behavior of matter and energy at the smallest scales, like atoms and subatomic particles. Unlike ...

A new analysis reveals what happens when very short or narrow electron beams encounter a particle. The research is published ...

An instrument that uses high-energy electrons to take "snapshots" of ultrafast chemical processes at the atomic and molecular ...

Scientists have proposed a surprising new way to detect gravitational waves—by observing how they change the light emitted by atoms. These waves can subtly shift photon frequencies in different ...

Reflected electron beams at quasi-perpendicular shocks generate a cascade of instabilities, contributing to their self-confinement and acceleration.
