Fig. 5: Channel-resolved electron wavepacket.
From: Attosecond dynamics of multi-channel single photon ionization

Amplitude (top row) and phase (bottom row) of the electron wavepackets as a function of kx and ky for a given time. Shown are the individual channels as well as the coherent sum of the λ = 0 and λ = 2 channels for the case of m = 0 (third column).
