SUB-ATOMIC MOTIONS: From capturing electrons to probing human health

Born at the dawn of the new millennium, attosecond “photography” has opened the door for capturing sub-atomic motions as they evolve in time. Control of the oscillating electric field of light has permitted the attosecond control of electrons with unprecedented precision in space and time.

Fundamental quantum phenomena, such as electron tunnelling and dipole oscillations in atoms or light-electron energy exchange in solids as well as fundamental classical phenomena, such as the field oscillations of visible light, became accessible to human observation in slow-motion replay.

These capabilities open new avenues for 21st-century science, technology and medicine. Some of them emerge from the ability to sample light fields with attosecond precision. Possible implications of these advances include hundred thousand times faster electronics and cost-effective monitoring of human health.
