ASTRA: a Transition-Density-Matrix Approach to Molecular Ionization
Juan Martín Randazzo, Carlos Marante, Siddhartha Chattopadhyay +3
We describe \ASTRA{} (AttoSecond TRAnsitions), a new close-coupling approach to molecular ionization that uses many-body transition density matrices between ionic states with arbit…

ASTRA, A Transition Density Matrix Approach to the Interaction of Attosecond Radiation with Atoms and Molecules
Juan M Randazzo, Carlos Marante, Siddhartha Chattopadhyay +4
A new formalism and computer code, ASTRA (AttoSecond TRAnsitions), has been developed to treat the interactions of short, intense radiation with molecules. The formalism makes exte…
