Author(s): Hari R. Varma, Marcelo F. Ciappina, Nina Rohringer, and Robin Santra
Two-photon above-threshold ionization processes in the x-ray regime are studied using atomic hydrogen as a model system. Within the minimal-coupling formalism of nonrelativistic quantum electrodynamics, two distinct interactions— A [over ̂] ⋅p [over ̂] in second order and A [over ̂] ^{2} in f...
