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…
Attosecond photoelectron spectroscopy of helium doubly excited states
Luca Argenti, Eva Lindroth
We describe a numerical method that simulates the interaction of the helium atom with sequences of femtosecond and attosecond light pulses. The method, which is based on the close-…
Autoionizing Polaritons in Attosecond Atomic Ionization
Nathan Harkema, Coleman Cariker, Eva Lindroth +2
Light-induced states are commonly observed in the photoionization spectra of laser-dressed atoms. The properties of autoionizing polaritons, entangled states of light and Auger res…
Towards the complete phase profiling of attosecond wave packets
Jaco Fuchs, Nicolas Douguet, Stefan Donsa +5
Realistic attosecond wave packets have complex profiles that, in dispersive conditions, rapidly broaden or split into multiple components. Such behaviors are encoded in sharp featu…
Coherent control of an Helium-Ion ensemble
Saad Mehmood, Eva Lindroth, Luca Argenti
Attosecond pulses can ionize atoms in a coherent process. Since the emerging fragments are entangled, however, each preserves only a fraction of the initial coherence, thus limitin…
Control of the Ion Polarization in the Pump-Probe Ionization of Helium
Saad Mehmood, Eva Lindroth, Luca Argenti
Attosecond pump-probe ionization process can be used to prepare atomic ions in the coherent superposition of states with opposite parity. The multiphoton shake-up ionization of Hel…
