Probing coherent electronic superpositions of singly- and doubly-excited states of krypton with attosecond four-wave mixing spectroscopy
S. Yanez-Pagans, M. A. Alarcon, C. H. Greene +1
Radiative nonlinear four-wave mixing can monitor the evolution of electronic wave packets, providing access to lifetimes and quantifies the light induced couplings between excited…

Non-perturbative Effects in Attosecond Four-Wave Mixing Spectra
Sergio Yanez-Pagans, Nathan Harkema, Arvinder Sandhu +2
We study the nonlinear optical response of argon to a four-wave-mixing pulse sequence consisting of an extreme ultraviolet pulse, an overlapping collinear IR and an non-collinear d…

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…
