Nonadiabatic tunneling in circularly polarized laser fields: Physical picture and calculations

I Barth, O Smirnova - Physical Review A—Atomic, Molecular, and Optical …, 2011 - APS
We consider selectivity of strong-field ionization in circularly polarized laser fields to the
sense of electron rotation in the laser polarization plane in the initial state. We show that, in …

Strong-field approximation for intense-laser–atom processes: The choice of gauge

D Bauer, DB Milošević, W Becker - Physical Review A—Atomic, Molecular, and …, 2005 - APS
The strong-field approximation (SFA) can be and has been applied in both length gauge
and velocity gauge with quantitatively conflicting answers. For ionization of negative ions …

Strong field approximation for systems with Coulomb interaction

SV Popruzhenko, D Bauer - Journal of Modern Optics, 2008 - Taylor & Francis
A theory describing above-threshold ionization of atoms and ions in a strong
electromagnetic field is presented. It is based on the widely known strong field …

Time-dependent analytical -matrix approach for strong-field dynamics. I. One-electron systems

L Torlina, O Smirnova - Physical Review A—Atomic, Molecular, and Optical …, 2012 - APS
We develop a flexible analytical approach to describe strong-field dynamics in atoms and
molecules. The approach is based on the ideas of the R-matrix method. Here, we illustrate …

Nonadiabatic tunneling in circularly polarized laser fields. II. Derivation of formulas

I Barth, O Smirnova - Physical Review A—Atomic, Molecular, and Optical …, 2013 - APS
We provide detailed analysis of strong field ionization of degenerate valence p orbitals by
circularly polarized fields. Our analytical approach is conceptually equivalent to the …

Quantum-orbit theory of high-order atomic processes in intense laser fields

DB MiloŠević*, D Bauer, W Becker - Journal of Modern Optics, 2006 - Taylor & Francis

The very pronounced intensity-dependent enhancements of groups of peaks of high-order
above-threshold-ionization spectra of rare-gas atoms are investigated using an improved …

Analytic theory of high-order-harmonic generation by an intense few-cycle laser pulse

MV Frolov, NL Manakov, AM Popov, OV Tikhonova… - Physical Review A …, 2012 - APS
We present a theoretical model for describing the interaction of an electron, weakly bound in
a short-range potential, with an intense, few-cycle laser pulse. General definitions for the …
