Quantum Optical Aspects of High-Harmonic Generation
Sándor Varró
The interaction of electrons with strong laser fields is usually treated with semiclassical theory, where the laser is represented by an external field. There are analytic solution…
Diatomic molecule in a strong infrared laser field: level-shifts and bond-length change due to laser-dressed Morse potential
Sándor Varró, Szabolcs Hack, Gábor Paragi +3
We present a general mathematical procedure to handle interactions described by a Morse potential in the presence of a strong harmonic excitation. We account for permanent and fiel…
Coherent and incoherent superposition of transition matrix elements of the squeezing operator
Sandor Varro
We discuss the general matrix elements of the squeezing operator between number eigenstates of a harmonic oscillator (which may also represent a quantized mode of the electromagnet…
A quantum optical description of photon statistics and cross-correlations in high harmonic generation
Ákos Gombkötő, Péter Földi, Sándor Varró
We present a study of photon statistics associated with high-order harmonic generation (HHG) involving one-mode and intermodal correlations of the high harmonic photons. The aim of…
The role of the time delay in the reflection and transmission of ultrashort electromagnetic pulses on a system of parallel current sheets
M. Polner, S. Varró, A. Vörös-Kiss
The reflection and transmission of a few-cycle laser pulse impinging on two parallel thin metal layers have been analyzed. The two layers, with a thickness much smaller than the sk…
Sub-cycle quantum electrodynamics in strongly laser-driven semiconductors
N. Tsatrafyllis, S. Kuhn, M. Dumergue +8
Electrodynamical processes induced in complex systems like semiconductors by strong electromagnetic fields, have traditionally/conventionally been described using semi-classical ap…
