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…
High-order harmonics as induced by a quantized field:a phase-space picture
Ákos Gombkötő, Sándor Varró, Péter Mati +1
The interaction of matter with a quantized electromagnetic mode is considered. Representing a strong exciting field, the mode is assumed to contain a large number of photons. As a…
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…
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…
Electron Acceleration by a Bichromatic Chirped Laser Pulse in Underdense Plasmas
Mihály András Pocsai, Imre Ferenc Barna, Sándor Varró
A theoretical study of laser and plasma based electron acceleration is presented. An effective model has been used, in which the presence of an underdense plasma has been taken acc…
Electron Acceleration in Underdense Plasmas Described with a Classical Effective Theory
Mihály András Pocsai, Imre Ferenc Barna, Sándor Varró
An effective theory of laser--plasma based particle acceleration is presented. Here we treated the plasma as a continuous medium with an index of refraction in which a sing…
Pair production at the edge of the QED flux tube
Dániel Berényi, Sándor Varró, Vladimir V. Skokov +1
We investigate the process of Abelian pair production in the presence of strong inhomogeneous and time-dependent external electric fields. The spatial dependence of the external fi…
