Non-linear Synthesis of Complex Laser Waveforms at Remote Distances
Nicolas Berti, Wahb Ettoumi, Sylvain Hermelin +2
Strong deformation of ultrashort laser pulse shapes is unavoidable when delivering high intensities at remote distances due to non-linear effects taking place while propagating. Re…
Spin-Glass Model Governs Laser Multiple Filamentation
Wahb Ettoumi, Jérôme Kasparian, Jean-Pierre Wolf
We show that multiple filamentation patterns in high-power laser beams, can be described by means of two statistical physics concepts, namely self-similarity of the patterns over t…
Laser filamentation as a new phase transition universality class
Wahb Ettoumi, Jérôme Kasparian, Jean-Pierre Wolf
We show that the onset of laser multiple filamentation can be described as a critical phenomenon that we characterize both experimentally and numerically by measuring a set of seve…
Reversibility of laser filamentation
Nicolas Berti, Wahb Ettoumi, Jérôme Kasparian +1
We investigate the reversibility of laser filamentation, a self-sustained, non-linear propagation regime including dissipation and time-retarded effects. We show that even losses r…
Phase Diagram of Ferroelastic Systems in the Presence of Disorder: Analytical Model and Experimental Verification
R. Vasseur, D. Xue, Y. Zhou +4
There is little consensus on the nature of the glass state and its relationship to other strain states in ferroelastic materials which show the shape memory effect and superelastic…
Action diffusion and lifetimes of quasistationary states in the Hamiltonian Mean Field model
Wahb Ettoumi, Marie-Christine Firpo
Out-of-equilibrium quasistationary states (QSSs) are one of the signatures of a broken ergodicity in long-range interacting systems. For the widely studied Hamiltonian Mean-Field m…
