Hybrid basis and multi-center grid method for strong-field processes
Kyle A. Hamer, Heman Gharibnejad, Luca Argenti +1
We present a time-dependent framework that combines a hybrid Gaussian-FEDVR basis with a multicenter grid to simulate strong-field and attosecond dynamics in atoms and molecules. T…
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…
The influence of final state interactions in attosecond photoelectron interferometry
Sizuo Luo, Robin Weissenbilder, Hugo Laurell +14
Fano resonances are ubiquitous phenomena appearing in many fields of physics, e.g. atomic or molecular photoionization, or electron transport in quantum dots. Recently, attosecond…
