Attosecond pulses are ultra-short light flashes widely used in modern physics to observe and control ultrafast electron dynamics.

The analysis

The retrieved papers consistently state that attosecond pulses/sources enable the observation, measurement, and manipulation of ultrafast electron dynamics, charge migration, and electronic wavepackets. There are no papers contradicting this core premise.
