Co-existing climate attractors in a coupled aquaplanet
Maura Brunetti, Jérôme Kasparian, Christian Vérard
The first step in exploring the properties of dynamical systems like the Earth climate is to identify the different phase space regions where the trajectories asymptotically evolve…
Ab-initio calculations of laser-atom interactions reveal harmonics feedback during macroscopic propagation
Nicolas Berti, Pierre Béjot, Eric Cormier +3
We couple the full 3D ab initio quantum evolution of the light pulse polarization in interaction with an atom with a propagation model to simulate the propagation of ultrashort las…
HV discharges triggered by dual- and triple-frequency laser filaments
Thomas Produit, Pierre Walch, Guillaume Schimmel +10
We study the use of frequency upconversion schemes of near-IR picosecond laser pulses and compare their ability to guide and trigger electric discharges through filamentation in ai…
Quantitative analysis of self-organized patterns in ombrotrophic peatlands
Chloé Béguin, Maura Brunetti, Jérôme Kasparian
We numerically investigate a diffusion-reaction model of an ombrotrophic peatland implementing a Turing instability relying on nutrient accumulation. We propose a systematic and qu…
