Variable coherence model for free-electron laser pulses
Austin Bartunek, Nils H. Sommerfeld, Francois Mauger
We introduce the variable coherence model (VCM) for simulating free-electron laser (FEL) pulses generated through self-amplified spontaneous emission. Building on the established p…
Extended phase-space symplectic integration for electron dynamics
Francois Mauger, Cristel Chandre
We investigate the use of extended phase-space symplectic integration for simulating two different classes of electron dynamics. The first one, with one and a half degrees of freed…
Configuration-interaction calculations with density-functional theory molecular orbitals for modeling valence- and core-excited states in molecules
Giorgio Visentin, Francois Mauger
We investigate configuration-interaction (CI) calculations on a basis of molecular orbitals generated by preliminary density-functional theory (DFT) calculations. We use this CI/DF…
QMol-grid: A MATLAB package for quantum-mechanical simulations in atomic and molecular systems
Francois Mauger, Cristel Chandre
The QMol-grid package provides a suite of routines for performing quantum-mechanical simulations in atomic and molecular systems, currently implemented in one spatial dimension. It…
Circularly Polarized Molecular High Harmonic Generation Using a Bicircular Laser
F Mauger, A. D. Bandrauk, T Uzer
We investigate the process of circularly polarized high harmonic generation in molecules using a bicircular laser field. In this context, we show that molecules offer a very robust…
Electronic dynamics and frequency-dependent effects in circularly polarized strong-field physics
Francois Mauger, A. D. Bandrauk
We analyze, quantum mechanically, the dynamics of ionization with a strong, circularly polarized, laser field. We show that the main source for non-adiabatic effects is connected t…
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…
Quantum-classical correspondence in circularly polarized high harmonic generation
Francois Mauger, A. D. Bandrauk, Adam Kamor +2
Using numerical simulations, we show that atomic high order harmonic generation, HHG, with a circularly polarized laser field offers an ideal framework for quantum-classical corres…
Annular billiard dynamics in a circularly polarized strong laser field
Adam Kamor, Francois Mauger, Cristel Chandre +1
We analyze the dynamics of a valence electron of the buckminsterfullerene molecule (C60) subjected to a circularly polarized laser field by modeling it with the motion of a classic…
Controlling double ionization of atoms in intense bichromatic laser pulses
Adam Kamor, Francois Mauger, Cristel Chandre +1
We consider the classical dynamics of a two-electron system subjected to an intense bichromatic linearly polarized laser pulse. By varying the parameters of the field, such as the…
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…
Recollisions and correlated double ionization with circularly polarized light
Francois Mauger, Cristel Chandre, Turgay Uzer
It is generally believed that the recollision mechanism of atomic nonsequential double ionization is suppressed in circularly polarized laser fields because the returning electron…
From recollisions to the knee: A road map for double ionization in intense laser fields
Francois Mauger, Cristel Chandre, Turgay Uzer
We examine the nature and statistical properties of electron-electron collisions in the recollision process in a strong laser field. The separation of the double ionization yield i…
Strong field double ionization of H2 : Insights from nonlinear dynamics
François Mauger, Cristel Chandre, T. Uzer
The uncorrelated (``sequential'') and correlated (``nonsequential'') double ionization of the H2 molecule in strong laser pulses is investigated using the tools of nonlinear dynami…
