Nonlinear Debye-Onsager-Relaxation-Effect
The quantum kinetic equation for charged particles in strong electric fields is used to derive the nonlinear particle flux. The relaxation field is calculated quantum mechanically up to any order in the applied field provided a given Maxwellian plasma. The classical limit is given in analytical form. In the range of weak fields the deformation of the screening cloud is responsible for the Debye...
متن کاملPhonon-polariton excitations in photonic crystals
The incorporation of materials which exhibit transverse phonon-polariton excitations into a photonic crystal produces an intricate optical system possessing unique and varied photon phenomena. In particular, we demonstrate theoretically that such a system will exhibit both near-dispersionless bands with field localization in the polaritonic material and metalliclike bands with complete flux exp...
متن کاملThe Nonlinear Debye-Onsager Relaxation Effect in Weakly Ionized Plasmas
A weakly ionized plasma under the influence of a strong electric field is considered. Supposing a local Maxwellian distribution for the electron momenta the plasma is described by hydrodynamic equations for the pair distribution functions. These equations are solved and the relaxation field is calculated for an arbitrary field strength. It is found that the relaxation effect becomes lower with ...
متن کاملNonlinear waves in granular crystals
We investigate excitations in one-dimensional granular crystals, i.e. chains of solid beads with nonlinear interaction forces. These chains have attracted attention because of their relative experimental simplicity and interesting dynamics. They can be modelled as chains of coupled oscillators in a model reminiscent of the celebrated Fermi-Pasta-Ulam (FPU) equations. The nonlinearity of the int...
متن کاملNonlinear Waves in Granular Crystals
The properties and stabilities of various wave types are investigated in nonlinear lattices with a ‘Hertz’ type potential. In particular the interaction of intrinsic localized modes with other waves is studied. Evidence is provided that Fano-like resonances, observed in other nonlinear systems, cannot occur in Hertzian lattices.
