Charges carried by wave packets that are superimposed on plane waves
Istvan Magashegyi, Katalin Oltyan, Peter Foldi
We consider the superposition of plane waves and localized wave packets. This kind of wave function can result from a local excitation of a particle described by a plane wave. For…
Ultrashort laser pulse driven currents in conductors: physical mechanisms and time scales
Istvan Magashegyi, Lorant Zs. Szabo, Peter Foldi
The response of conduction band electrons to a local, pulse-like external excitation is investigated. The charge density wave packets that emerge as a consequence of the excitation…
Sturmian-Floquet approach to high-order harmonic generation
Jozsef Kasza Peter Dombi, Peter Foldi
We show that the Floquet approach with a Sturmian basis means an efficient description of high-order harmonic generation with monochromatic excitation. This method, although involv…
Gauge invariance and the interpretation of inter- and intraband processes in high-order harmonic generation from bulk solids
Peter Foldi
A theoretical model for high-order harmonic generation (HHG) in bulk solids is considered. Our approach treats laser-induced inter- and intraband currents on an equal footing. The…
A quantum optical model for the dynamics of high harmonic generation
Ákos Gombkötő, Attila Czirják, Sándor Varró +1
We investigate a two-level atom in the field of a strong laser pulse. The resulting time-dependent polarization is the source of a radiation the frequency components of which are e…
Correlations between the final momenta of electrons and their initial phase-space distribution in the process of tunnel ionization
Viktor Ayadi, Peter Foldi, Peter Dombi +1
We present both full quantum mechanical and semiclassical calculations of above threshold ionization (ATI) of a hydrogen atom in the tunneling regime by a few-cycle linearly polari…
