Two-photon absorption in semiconductors: a multi-band length-gauge analysis
W. -R. Hannes, M. F. Ciappina
The simplest approach to deal with light excitations in direct-gap semiconductors is to model them as a two-band system: one conduction and one valence band. For such models, parti…
High-order harmonic generation in atomic and molecular systems
Noslen Suárez, Alexis Chacón, Jose A. Pérez-Hernández +3
High-order harmonic generation (HHG) results from strong-field laser matter interaction and it is one of the main processes that are used to extract electron structural and dynamic…
Above-Threshold Ionization and Laser-Induced Electron Diffraction in Diatomic Molecules
N. Suárez, A. Chacón, M. F. Ciappina +3
Strong field photoemission and electron recollision provide a viable route to extract electronic and nuclear dynamics from molecular targets with attosecond temporal resolution. Ho…
Carrier-wave Rabi flopping signatures in high-order harmonic generation for alkali atoms
M. F. Ciappina, J. A. Pérez-Hernández, A. S. Landsman +4
We present the first theoretical investigation of carrier-wave Rabi flopping in real atoms by employing numerical simulations of high-order harmonic generation (HHG) in alkali spec…
Tailoring high-order harmonic generation with nonhomogeneous fields and electron confinement
M. F. Ciappina, Srdjan S. Acimovic, T. Shaaran +3
We study high-order harmonic generation (HHG) resulting from the illumination of plasmonic nanostructures with a short laser pulse. We show that both the inhomogeneities of the loc…
