Dimensionality and dissipation in Langmuir collapse Journal Article uri icon

Overview

abstract

  • The nonlinear Schrödinger equation provides a model for Langmuir evolution at low energy density and wavenumber. This equation is studied using virial theorem techniques. Stationary solitons and pulsating solitons (related to ’’breathers’���) are found in one dimension, as well as collapsing packets in two or more dimensions. Initial wave-packet collapse thresholds and times are found, with and without constant collisional damping. In three dimensions, a narrow collapsing core is observed to break away from an initial Gaussian packet and become asymptotically self-similar with time.
