Coherent buildup of high harmonic radiation: the classical perspective
S. A. Berman, J. Dubois, C. Chandre +2
We present a classical model for high harmonic generation during the propagation of an intense laser pulse through an atomic gas. Numerical simulations of the model show excellent…
Recollision scenario without tunneling : Role of the ionic core potential
Adam Kamor, Cristel Chandre, Turgay Uzer +1
The standard model of strong laser physics, the recollision scenario, omits the ionic core potential after tunneling. Strikingly, although the Coulomb interaction drives all stages…
Mechanism of delayed double ionization in a strong laser field
Francois Mauger, Adam Kamor, Cristel Chandre +1
When intense laser pulses release correlated electrons, the time delay between the ionizations may last more than one laser cycle. We show that this "Recollision-Excitation with Su…
Delayed double ionization as a signature of Hamiltonian chaos
Francois Mauger, Adam Kamor, Cristel Chandre +1
We analyze the dynamical processes behind delayed double ionization of atoms subjected to strong laser pulses. Using reduced models, we show that these processes are a signature of…
Strong field double ionization: What is under the "knee"?
François Mauger, Cristel Chandre, T. Uzer
Both uncorrelated ("sequential") and correlated ("nonsequential") processes contribute to the double ionization of the helium atom in strong laser pulses. The double ionization pro…
Hydrogen atom in crossed electric and magnetic fields: Phase space topology and torus quantization via periodic orbits
Stephan Gekle, Jörg Main, Thomas Bartsch +1
A hierarchical ordering is demonstrated for the periodic orbits in a strongly coupled multidimensional Hamiltonian system, namely the hydrogen atom in crossed electric and magnetic…
