Based on the sudden perturbation approximation and sequential three-stage model of laser-assisted x-ray photoionization, we refine the theory of attosecond...
We study analytically the photoionization of a coherent superposition of electronic states and show that chirped pulses can measure attosecond time scale...

For the first time, the Coulomb continuum effects in asymmetric molecular interference have been studied analytically in photoionization, photorecombination,...
We develop a description of laser-assisted x-ray photoionization based on a sudden approximation approach. By splitting the system evolution into three time...
When an attosecond X-ray pulse ionizes atoms in a strong laser field, the field deflects the emitted photoelectrons. This deflection depends on the phase of...
Physical Review. A, American Physical Society, 2005, Volume : 72, Numéro : 5
We study analytically the photoionization of a coherent superposition of atomic and molecular electronic states by an ultrashort, attosecond x-ray pulse. We...
We show that the complete characterization of arbitrarily short isolated attosecond x-ray pulses can be achieved by applying spectral shearing interferometry...
We solve the time-dependent Schrödinger equation in three dimensions for H+2 in a one-cycle laser pulse of moderate intensity. We consider fixed nuclear...
Journal of Modern Optics, 10 mai 2005, Volume : 52, Numéro : 7
We propose a novel mechanism of energy absorption in dielectric materials with ultrashort infrared laser pulses of intensities below the damage threshold....
