A continuous-mode quantum-optical representation of finite strong-field laser pulses in free space
Szabolcs Hack, Attila Czirják, Péter Földi
We formulate an energy-consistent quantum-optical representation of finite paraxial laser pulses in free space. The formulation is based on a continuous-mode description and provid…
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…
Interference-induced phenomena in high-order harmonic generation from bulk solids
Viktor Szaszkó-Bogár, Katalin Varjú, Péter Földi
We consider a quantum mechanical model for the high-order harmonic generation in bulk solids. The bandgap is assumed to be considerably larger than the exciting photon energy. Usin…
Networks of quantum nanorings: programmable spintronic devices
Peter Foldi, Orsolya Kalman, Mihaly G. Benedict +1
An array of quantum rings with local (ring by ring) modulation of the spin orbit interaction (SOI) can lead to novel effects in spin state transformation of electrons. It is shown…
Dynamics of periodic anticrossings: Decoherence, pointer states and hysteresis curves
Peter Foldi, Mihaly G. Benedict, F. M. Peeters
We consider a strongly driven two-level (spin) system, with a periodic external field that induces a sequence of avoided level crossings. The spin system interacts with a bosonic r…
Dynamics of molecular nanomagnets in time-dependent external magnetic fields: Beyond the Landau-Zener-Stückelberg model
P. Foldi, M. G. Benedict, J. M. Pereira +1
The time evolution of the magnetization of a magnetic molecular crystal is obtained in an external time-dependent magnetic field, with sweep rates in the kT/s range. We present the…
