  • Higher-order corrections to dust ion-acoustic soliton in a quantum dusty plasma
    Physics of Plasmas, 2010
    Co-Authors: Prasanta Chatterjee, Ganesh Mondal, Sithi V. Muniandy, Brindaban Das, Chiow San Wong
    Abstract:

    Dust ion-acoustic soliton is studied in an electron-dust-ion plasma by employing a two-fluid quantum hydrodynamic model. Ions and electrons are assumed to follow quantum mechanical behaviors in dust background. The Korteweg-de Vries (KdV) Equation and higher order contribution to KdV Equations are derived using reductive perturbation technique. The higher order contribution is obtained as a higher order Inhomogeneous Differential Equation. The nonsecular solution of the higher order contribution is obtained by using the renormalization method and the particular solution of the Inhomogeneous Equation is determined using a truncated series solution method. The effects of dust concentration, quantum parameter for ions and electrons, and soliton velocity on the amplitude and width of the dressed soliton are discussed.

  • Dressed solitons in quantum electron-positron-ion plasmas
    Physics of Plasmas, 2009
    Co-Authors: Prasanta Chatterjee, Kaushik Roy, Ganesh Mondal, Sithi V. Muniandy, Seong Ling Yap, Chiow San Wong
    Abstract:

    Nonlinear propagation of quantum ion acoustic waves in a dense quantum plasma whose constituents are electrons, positrons, and positive ions is investigated using a quantum hydrodynamic model. The Korteweg–de Vries Equation is derived using reductive perturbation technique. The higher order Inhomogeneous Differential Equation is obtained for the dressed soliton. The dynamical Equation for dressed soliton is solved using the renormalization method. The conditions for the validity of the higher order correction are described. The effects of quantum parameter, positron concentration, electron to positron Fermi temperature ratio, and soliton velocity on the amplitude and width of the dressed soliton are studied.

  • Generation of a dressed soliton in a four-component dusty plasma with nonthermal ions
    Physics of Plasmas, 2009
    Co-Authors: Prasanta Chatterjee, Kaushik Roy, Ganesh Mondal, Sithi V. Muniandy, Seong Ling Yap, Chiow San Wong
    Abstract:

    Dust acoustic solitary waves are studied in a four-component dusty plasma. Positively and negatively charged mobile dust and Boltzmann-distributed electrons are considered. The ion distribution is taken as nonthermal. The Korteweg–de Vries Equation is derived using reductive perturbation technique. We are able to reproduce the results obtained by Sayed and Mamun [Phys. Plasmas 14, 014501 (2007)] provided the Boltzmann distribution is considered for the ions. Higher order Inhomogeneous Differential Equation is obtained for the dressed soliton. By using the renormalization method of Kodama and Taniuti [J. Phys. Soc. Jpn. 45, 298 (1978)], we derived the expression for the dressed soliton.

  • Higher-order nonlinear electron-acoustic solitary excitations in partially degenerate quantum electron-ion plasmas
    Indian Journal of Physics, 2012
    Co-Authors: M. Akbari-moghanjoughi
    Abstract:

    Propagation of dressed solitary excitations are studied in a partially degenerate quantum plasma in the framework of quantum-hydrodynamics (QHD) model using multiple scales technique. The evolution Equation together with a linear Inhomogeneous Differential Equation is solved using Kodama-Taniuti renormalizing technique. It is shown that the type of solitary excitations (bright or dark) is defined by two critical plasma parameter values.Comment: To appear in Indian Journal of Physic

  • Dressed electrostatic solitary waves in quantum dusty pair plasmas
    Physics of Plasmas, 2010
    Co-Authors: M. Akbari-moghanjoughi
    Abstract:

    Quantum-hydrodynamics model is applied to investigate the nonlinear propagation of electrostatic solitary excitations in a quantum dusty pair plasma. A Korteweg de Vries evolution Equation is obtained using reductive perturbation technique and the higher-nonlinearity effects are derived by solving the linear Inhomogeneous Differential Equation analytically using Kodama–Taniuti renormalizing method. The possibility of propagation of bright- and dark-type solitary excitations is examined. It is shown that a critical value of quantum diffraction parameter H exists, on either side of which, only one type of solitary propagation is possible. It is also found that unlike for the first-order amplitude component, the variation of H parameter dominantly affects the soliton amplitude in higher-order approximation. The effect of fractional quantum number density on compressive and rarefactive soliton dynamics is also discussed.
