Co-evolution of density and topology in a simple model of city formation
Marc Barthelemy, Alessandro Flammini
We study the influence that population density and the road network have on each others' growth and evolution. We use a simple model of formation and evolution of city roads which…
Quasimonoenergetic electron beams produced by colliding cross-polarized laser pulses in underdense plasmas
C. Rechatin, J. Faure, A. Lifschitz +3
The interaction of two laser pulses in an underdense plasma has proven to be able to inject electrons in plasma waves, thus providing a stable and tunable source of electrons. Wher…
Temporal self-restoration of compressed optical filaments
L. Berge, S. Skupin, G. Steinmeyer
We numerically investigate the propagation of a self-compressed optical filament through a gas-glass-gas interface. Few-cycle light pulses survive a sudden and short order-of-magni…
Variational multiparticle-multihole configuration mixing method applied to pairing correlations in nuclei
N. Pillet, J. -F. Berger, E. Caurier
Applying a variational multiparticle-multihole configuration mixing method whose purpose is to include correlations beyond the mean field in a unified way without particle number a…
Sampling constraints in average: The example of Hugoniot curves
Jean-Bernard Maillet, Gabriel Stoltz
We present a method for sampling microscopic configurations of a physical system distributed according to a canonical (Boltzmann-Gibbs) measure, with a constraint holding in averag…
Consequences of anisotropy in electrical charge storage: application to the characterization by the mirror method of TiO2 rutile
Gilles Damamme, Christelle Guerret-Piecourt, Temga Temga +2
This article is devoted first to anisotropic distributions of stored electric charges in isotropic materials, second to charge trapping and induced electrostatic potential in aniso…
