Measuring autoionization decay lifetimes of optically forbidden inner valence excited states in neon atoms with attosecond noncollinear four wave mixing spectroscopy
Nicolette G. Puskar, Yen-Cheng Lin, James D. Gaynor +8
Attosecond noncollinear four wave mixing spectroscopy with one attosecond extreme ultraviolet (XUV) pulse and two few-cycle near-infrared (NIR) pulses was used to measure the autoi…
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…
Autoionizing polaritons with the Jaynes-Cummings model
Coleman Cariker, Sergio Yanez-Pagans, Nathan Harkema +3
Intense laser pulses have the capability to couple resonances in the continuum, leading to the formation of a split pair of autoionizing polaritons. These polaritons can exhibit ex…
Ionic Coherence in Resonant Above-Threshold Attosecond Ionization Spectroscopy
Saad Mehmood, Eva Lindroth, Luca Argenti
The ionization of atoms with sequences of attosecond pulses gives rise to excited ionic states that are entangled with the emitted photoelectron. Still, the ionic ensemble preserve…
Multi-polariton control in attosecond transient absorption of autoionizing states
S. Yanez-Pagans, C. Cariker, M. Shaikh +2
Tunable attosecond transient absorption spectroscopy is an ideal tool for studying and manipulating autoionization dynamics in the continuum. We investigate near-resonant two-photo…
