Open-Loop and Closed-Loop Vortex Filaments in Laser-Matter Interactions

Laser-Matter interactions on ns time scale. Kelvin-Helmholtz instability and generation of vortex filaments on metal targets. Ultrafast cooling and conservation of vortex filament structures. Open-loop filaments: Observation of helical pairing: Observation of the cascade unbraiding, and of the cascade reconnection of vortex filaments. Closed-loop filaments: First observation of unknotted and knotted filament structures of various degree of topological complexity ; vortex rings, Hopf links, trefoil knots...in the real experiment
