Laser induced distortion of band structure in solids: an analytic model
Sándor Varró, Péter Földi, Imre Ferenc Barna
We consider a spatially periodic (cosine) potential as a model for a crystalline solid that interacts with a harmonically oscillating external electric field. This problem is perio…
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…
Parametric study of cycle modulation in laser driven ion beams and acceleration field retrieval at femtosecond time scale
Matthias Schnürer, Julia Braenzel, Andrea Lübcke +1
High frequency modulations appearing in the kinetic energy distribution of laser accelerated ions are proposed for retrieving the acceleration field dynamics at femtosecond time sc…
Dynamically Assisted Schwinger Effect at Strong Coupling with Its Holographic Extension
Chen Lan, Yi-Fan Wang, Huifang Geng +1
At strong-coupling and weak-field limit, the scalar Schwinger effect is studied by the field-theoretical method of worldline instantons for dynamic fields of single-pulse and sinus…
Photoionisation of Rubidium in strong laser fields
Mihály András Pocsai, Imre Ferenc Barna, Károly Tőkési
The photoionisation of rubidium in strong infra-red laser fields based on ab initio calculations was investigated. The bound and the continuum states are described with Slater orbi…
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…
Ultrafast Studies of Hot-Hole Dynamics in Au/p-GaN Heterostructures
Giulia Tagliabue, Joseph S. DuChene, Mohamed Abdellah +9
Harvesting non-equilibrium hot carriers from photo-excited metal nanoparticles has enabled plasmon-driven photochemical transformations and tunable photodetection with resonant nan…
Dynamic stabilization of plasma instability
S. Kawata, T. Karino, Y. J. Gu
The paper presents a review of dynamic stabilization mechanisms for plasma instabilities. One of the dynamic stabilization mechanisms for plasma instability was proposed in the pap…
Semiclassical two-step model for ionization of hydrogen molecule by strong laser field
N. I. Shvetsov-Shilovski, M. Lein, K. Tőkési
We extend the semiclassical two-step model for strong-field ionization that describes quantum interference and accounts for the Coulomb potential beyond the semiclassical perturbat…
Attosecond bunches of gamma photons and positrons generated in nanorod array targets
Zsolt Lécz, Alexander Andreev
The sub-atomic experimental exploration of physical processes on extremely short time scales has become possible by the generation of high quality electron bunches and x-ray pulses…
Scattering of charged particles on two spatially separated time-periodic optical fields
Lóránt Zs. Szabó, Mihály G. Benedict, Péter Földi
We consider a monoenergetic beam of moving charged particles interacting with two separated oscillating electric fields. Time-periodic linear potential is assumed to model the ligh…
Multiple ionization of argon via xuv-photon absorption induced by 20-gigawatt high-harmonic pulses
A. Nayak, I. Orfanos, I. Makos +10
We report the observation of multiple ionization of Argon through multi-XUV-photon absorption induced by an unprecedentedly powerful laser driven high-harmonic-generation source. C…

Szilárd Majorosi, Mihály G. Benedict, Attila Czirják
Based on a plausible requirement for the ground state density, we introduce a novel one-dimensional (1D) atomic model potential for the 1D simulation of the quantum dynamics of a s…

Imre F. Barna, Mihály A. Pocsai, L. Mátyás
In the present study a particular case of Gross-Pitaevskii or non-linear Schrödinger equation is rewritten to a form similar to a hydrodynamic Euler equation using the Madelung tra…
Thermal lensing measurements of Ti: Sapphire crystal pumped at 80 MHz picosecond pulses by Shack-Hartmann wavefront sensor
Mukhtar Hussain, Tayyab Imran, Adam Borzsonyi
The thermal lensing effects in the lasing crystal appear to be dominant when the pump laser focused on the lasing crystal which causes the local heating effect. The spatial refract…
