  • Shock waves in magnetized electronegative plasma with nonextensive electrons
    Eur. Phys. J. D (IF 1.331) Pub Date : 2020-05-28
    Salah K. El-Labany, Ebraheem E. Behery, Hosam N. Abd El-Razek, Lamiaa A. Abdelrazek

    Abstract The nonlinear properties of ion acoustic shock waves in a magnetized electronegative plasma with nonextensive electrons and stationary dust grains are studied. The reductive perturbation technique is applied to derive the Zakharov–Kuznetsov Burgers (ZKB) equation. The Tanh method is used to obtain the shock wave solution. The present model is applied to four different electronegative plasma

  • Molecular-frame (e, 2e) ionization dynamics of H 2 at high impact-energy

    Enliang Wang, Esam Ali, Xingyu Li, Xueguang Ren, Xiangjun Chen, Don Madison, Alexander Dorn

    Abstract We report a combined experimental and theoretical study on the electron-impact ionization dynamics of H2 at an impact-energy of 520 eV. The molecular-frame fivefold-differential cross sections were measured for electron emission in the plane perpendicular to the incoming projectile beam. An (e, 2e + ion) triple coincidence method was used covering projectile scattering angles of 6.5°, 10.0°

    Abstract Whenever light is slowed down, for any cause, two different formulas give its momentum. The coexistence of those momenta was the heart of the century-old Abraham-Minkowski dilemma, recently resolved for dielectrics. We demonstrate that this framework extends to momentum exchange in wave-particle interaction; in particular to vacuum waveguides of electron tubes (dispersive metallic slow-wave

    Abstract The encapsulation of nanowires (NWs) into single-walled carbon nanotubes (SWCNTs) is of great significance due to the specific mechanical, electrical and magnetic properties of confined NWs as well as application of filled CNTs in nanoelectromechanical systems (NEMS). The tensile behavior of NWs encapsulated-SWCNTs (NWs@SWCNTs) is investigated herein using molecular dynamics (MD) simulations

    Abstract Cationic clusters of gold, containing up to 8 atoms, and decorated with molecular hydrogen and water, were investigated with mass spectrometry. The clusters were grown as neutrals in superfluid helium nanodroplets that were ionized by electron impact. The resulting gas phase cluster cations exhibit magic sizes corresponding to the number of H2 molecules that form the first solvation layer

    Abstract By constructing a hydrodynamic canonical formalism, we show that the occurrence of an arbitrary density-dependent gauge potential in the meanfield Hamiltonian of a Bose-condensed fluid invariably leads to nonlinear flow-dependent terms in the wave equation for the phase, where such terms arise due to the explicit dependence of the mechanical flow on the fluid density.

    Abstract We propose a scheme to realize stable linear and nonlinear propagation of symmetric and antisymmetric surface plasmon polaritons (SPPs) solitons by doping ladder-type three-level quantum emitters into the middle layer of a metal-dielectric-metal (MDM) waveguide. In linear propagation regime, we show that both symmetric and antisymmetric SPPs can acquire a gain from electromagnetically induced

    Abstract In this work, we discuss the possibility of inertial sensing with positronium in the 23S metastable state for the measurement of optical dipole, relativistic and gravitational forces on a purely leptonic matter-antimatter system. Starting from the characteristics of an available 23S beam, we estimate the time necessary to measure accelerations ranging from ~105 m/s2 to 9.1 m/s2 with two different
