Strong-field Photoionization: Analysis of Overlapping Above-Threshold Ionization and Laser-Assisted Photoemission Structures
Candelaria Migliaro, Juan Martin Randazzo, Renata Della Picca
We present a theoretical description of atomic strong-field photoionization. Specifically, we consider an atom driven by a combination of two electromagnetic fields: a high-frequen…
Nondipole circularly polarized laser-assisted photoelectron emission
R. Della Picca, J. M. Randazzo, S. D. López +2
We theoretically study atomic laser-assisted photoelectric emission (LAPE) beyond the electric dipole approximation. We present a theoretical description for first-order nondipole…
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…
Laser-assisted photoionization: beyond the dipole approximation
Renata Della Picca, Juan Martín Randazzo, Sebastián David López +2
We present a theoretical study of atomic laser-assisted photoionization emission (LAPE) beyond the dipole approximation. By considering the non-relativistic non-dipole strong-field…
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…
Endohedrally confined hydrogen atom with a moving nucleus
Juan M. Randazzo, Carlos A. Rios
We studied the hydrogen atom as a system of two quantum particles in different confinement conditions; a spherical-impenetrable-wall cavity and a fullerene molecule cage. The motio…
