SEMINAR: Benchmark Calculations of Atomic Collision Processes

The rapid development of computational resources has resulted in enormous improvements in the accuracy of numerical calculations of atomic collision processes. In this talk I will concentrate on recent advances in the computational treatment of charged-particle and intense short-pulse laser interactions with atoms, ions, and small molecules. Examples include electron collisions with heavy complex targets that are of significant importance in many modeling applications in plasma and astrophysics, fundamental studies of highly correlated 4-body Coulomb processes such as simultaneous ionization with excitation, and the accurate solution of the time-dependent Schrödinger equation in the presence of intense, few-cycle femto/attosecond laser fields, which paves the way for quantum dynamic imaging and coherent control.
