The dynamics of electrons changes ever so slightly on each interaction with a photon. The group of Prof. Ursula Keller has now measured such interplay in its arguably purest form — by recording the attosecond-scale changes associated with one-photon transitions of an unbound electron. The photoelectric effect, whereby photons impinging on matter cause the emission […]
