Attophysics

Attophysics also known as attoscience is a branch of physics wherein attosecond (10−18 s) duration pulses of electrons or photons are used to probe dynamic processes in matter with unprecedented time resolution. The majority of attoscience employs pump–probe methods. One of the primary goals of attosecond science is to provide more insights into the dynamics of electrons in molecules. Today, attophysicists mostly study molecular phenomena, such as how a particular protein breaks down under X-ray bombardment.
