Attosecond physics, also known as attophysics, or more generally attosecond science, is a branch of physics that deals with light–matter interaction phenomena wherein attosecond (10−18 s) photon pulses are used to investigate dynamical processes in matter with unprecedented temporal resolution. The main research topics in this field are: Atomic physics: investigation of electron correlation effects, photo-emission delay and ionization tunneling.
