We are pursuing research centered on laser-atom interactions at high
intensity. Present-day laser sources are achieving ever more intense
beams which are opening new dimensions to the manipulation of atoms
and molecules and to the observation of nonlinear phenomena. The
atom is driven by the laser forces which become comparable
or superior to the internal atomic electric forces.
We have pioneered electron-atom scattering theory in laser fields,
the development of quasi-stationary-state (Floquet) solutions for
single- and multi-electron atomic systems, and the explicit (numerical)
solution of the time-dependent equations for atomic hydrogen atoms
in ultrastrong laser fields.
To this effect, we are employing a range of analytical and numerical
techniques. For the solution of the physical models, we rely strongly
on numerical techniques, employing a wide range of computer platforms
ranging from PCs to parallel supercomputers. We speak fortran (77 and
90) and use Mathematica for symbolic manipulation. Our local computing
resources comprise three SUN workstations and several PCs, while the
ULB computing center provides an SGI multiprocessor computer and a
CRAY J19 supercomputer. Our international collaborations give us access
to further computing facilities abroad.
Current central research themes focus on one hand on the transition
to the relativistic regime at ultrahigh laser intensity and on the
other on the correlated multielectron multiphoton effects arising
in ionization of atoms by strong lasers.
Thèmes the recherche proposés:
- Two-color resonances in multiphoton processes
- Two-electron atoms in intense laser fields
- Relativistic laser-atom interactions
- Laser-assisted electron-atom collisions
