Attosecond science allows the extremely fast movements of electron particles to be observed. This emerging field brings both opportunity and controversy.

These extremely short attosecond pulses also carry more energy—especially when generated using a free-electron laser ... be enabled by several important principles from quantum physics.

As a final step, the researchers used another laser pulse to deliberately perturb the electron sea in the graphene sample while the electron wave was propagating. By including the second laser ...
