    Topological jamming and the glass transition in a frustrated system

    The relationship between extended structures, glassy dynamics and an underlying critical point is examined in the context of a lattice model of fluctuating lines. Monte Carlo simulations are used to construct ...

    Effect of Gaussian Spectral Intensity Distribution of the Incident Radiation on Photometric Detection

    The effect of gaussian spectral intensity profile of the incident radiation on photometric efficiency of detection is studied by spectral integration and by considering photopic spectral responsivity of a dete...

    Plasma confinement and other effects of magnetic moment from standing waves in Vlasov plasma

    A non-oscillating (zero-harmonic) spatially varying magnetic moment, from the wave-induced bending of the direction of motion of charged constitutents of a Vlasov plasma, along the path of a standing-wave patt...

    Power Coupling from Led to Optical System

    Light coupling from a Light Emitting Diode (LED) to an optical system is discussed on the basis of the Hasegawa model. Photometric calculations are also presented to show the variations in power coupling due t...

    Magnetic field generation from Alfven waves propagating along helical lines of force

    A static induced magnetization of Alfven waves (IMAW) due to the inverse Faraday effect is defined and studied. The Alfven waves are assumed to propagate along helical lines of force of a force-free ambient ma...

    Nonlinear shift of wave parameters of whistlers in the ionosphere

    The expression for nonlinear shift of a wave number of a whistler wave propagating through the ionosphere has been derived and the results have been discussed. It is seen that nonlinear shift of a wave number ...

    Whistlers as a diagnostic technique in the lower ionosphere

    We have taken a plasma model of ionosphere which is quite different from the earlier model employed by several workers to study the whistler as a diagnostic technique in the ionosphere. In contrast to the earl...

    Nonlinear propagation of whistlers in the ionosphere

    In this paper, the nonlinear dispersion relation for whistlers in the ionosphere has been derived and then the group travel time for an ion-cyclotron whistler from its source to an observer at the satellite ha...

    Small amplitude wave propagation in stratified media

    Four mutually connected first order linear differential equations for a system of two waves — constituting a set of mathematical models are developed. Small amplitude wave propagation through stratified media ...
