Nonadiabatic effects in the double ionization of atoms driven by a circularly polarized laser pulse
J. Dubois, C. Chandre, T. Uzer
We study the double ionization of atoms subjected to circularly polarized (CP) laser pulses. We analyze two fundamental ionization processes: the sequential (SDI) and non-sequentia…
Double-ionization mechanisms of magnesium driven by electron impact
Shivan Mittal, Jonathan Dubois, Cristel Chandre +1
We study double ionization of Mg by electron impact through the vantage point of classical mechanics. We consider all electron-electron correlations in a Coulomb four-body problem,…
Envelope-driven recollisions triggered by an elliptically polarized laser pulse
Jonathan Dubois, C. Chandre, T. Uzer
Increasing ellipticity usually suppresses the recollision probability drastically. In contrast, we report on a recollision channel with large return energy and a substantial probab…
Inclusion of Coulomb effects in laser-atom interactions
Jonathan Dubois, Simon Berman, Cristel Chandre +1
We investigate the role of the Coulomb interaction in strong field processes. We find that the Coulomb field of the ion makes its presence known even in highly intense laser fields…
Classical versus quantum views of intense laser pulse propagation in gases
S. A. Berman, C. Chandre, J. Dubois +2
We study the behavior of reduced models for the propagation of intense laser pulses in atomic gases. The models we consider incorporate ionization, blueshifting, and other nonlinea…
Guiding-center motion for electrons in strong laser fields
Jonathan Dubois, S. Berman, C. Chandre +1
We consider the dynamics of electrons in combined strong laser and Coulomb fields. Under a timescale separation condition, we reduce this dynamics to a guiding-center framework. Mo…
