Stochastic treatment of finite-N effects in mean-field systems and its application to the lifetimes of coherent structures
W. Ettoumi, M. -C. Firpo
A stochastic treatment yielding to the derivation of a general Fokker-Planck equation is presented to model the slow convergence towards equilibrium of mean-field systems due to fi…

On negative higher-order Kerr effect and filamentation
V. Loriot, P. Béjot, W. Ettoumi +7
As a contribution to the ongoing controversy about the role of higher-order Kerr effect (HOKE) in laser filamentation, we first provide thorough details about the protocol that has…

Linear theory and violent relaxation in long-range systems: a test case
Wahb Ettoumi, Marie-Christine Firpo
In this article, several aspects of the dynamics of a toy model for longrange Hamiltonian systems are tackled focusing on linearly unstable unmagnetized (i.e. force-free) cold equi…
