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…
Quantum interference in strong-field ionization by a linearly polarized laser pulse, and its relevance to tunnel exit time and momentum
Szabolcs Hack, Szilárd Majorosi, Mihály G. Benedict +2
We investigate the liberation of an atomic electron by a linearly polarized single-cycle near-infrared laser pulse having a peak intensity that ensures tunneling. Based on phase sp…
Density-based one-dimensional model potentials for strong-field simulations in , and
Szilárd Majorosi, Mihály G. Benedict, Ferenc Bogár +2
We present results on the accurate one-dimensional (1D) modeling of simple atomic and molecular systems excited by strong laser fields. We use atomic model potentials that we deriv…
Reconstruction of tunnel exit time and exit momentum in strong field ionization, based on phase space methods
Szabolcs Hack, Szilárd Majorosi, Mihály Benedict +1
We analyze tunnel ionization of a single atom based on the Wigner function over the classical phase space which inspires improved classical electron trajectories: these start with…
Improved one-dimensional model potentials for strong-field simulations
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…
Carrier-envelope phase controlled isolated attosecond pulses in the nm wavelength range, based on superradiant nonlinear Thomson-backscattering
Szabolcs Hack, Sándor Varró, Attila Czirják
A proposal for a novel source of isolated attosecond XUV -- soft X-ray pulses with a well controlled carrier-envelope phase difference (CEP) is presented in the framework of nonlin…
Quantum entanglement in strong-field ionization
Szilárd Majorosi, Mihály G. Benedict, Attila Czirják
We investigate the time-evolution of quantum entanglement between an electron, liberated by a strong few-cycle laser pulse, and its parent ion-core. Since the standard procedure is…
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…
Relativistic electron transport through an oscillating barrier: wave packet generation and Fano-type resonances
Lóránt Zs. Szabó, Mihály G. Benedict, Attila Czirják +1
Transport properties of massive Dirac particles are investigated through an oscillating barrier. The Floquet quasienergies related to the time-dependent potential appear both in tr…
