Abstract

The dynamics of an ionization and a recombination in an ultrastrong laser field is studied by ab initio numerical simulations performed for a realistic atomic system in the regime of attosecond laser pulse duration. In particular the stabilization phenomenon is studied, the presence of which is confirmed in 3D. We first describe the method of integrating the Schrödinger equation (in general parabolic equations) which we adopt, taking advantage of the axial symmetry of the studied system and uses the FFT and Chebyshev polynomials (FCP) method. Further we present its implementation based on the CUDA technology to benefit from the power of graphics cards.
