    Solitons of the KP equation in dusty plasma with variable dust charge and two temprature iopns: energy and stability 

    Type: Journal Paper
    Author : Hamid Reza Pakzad; کورش جاویدان; Kurosh Javidan
    Year: 2009
    Abstract:

    The propagation of nonlinear waves in dusty plasmas with variable dust charge and two temperature ions is analyzed. By using the reductive perturbation theory, the Kadomtsev-Petvishvili (KP) equation is derived. A sagdeev ...

    Colliding solitary waves in quark gluon plasmas 

    Type: Journal Paper
    Author : اعظم رفیعی; کورش جاویدان; Azam Rafiei; Kurosh Javidan
    Year: 2016
    Abstract:

    We study the head-on collision of propagating waves due to perturbations in quark gluon plasmas. We use the Massachusetts Institute of Technology bag model, hydrodynamics equation, and suitable equation of state for ...

    Obliquely propagating electron acoustic solitons in a magnetized plasma with superthermal electrons 

    Type: Journal Paper
    Author : کورش جاویدان; H R Pakzad; Kurosh Javidan
    Year: 2012
    Abstract:

    The problem of small amplitude electron acoustic solitary waves is discussed using the reductive erturbation theory in magnetized plasmas consisting of cold electrons, hot electrons obeying superthermal distribution and stationary ions. The effects...

    Cylindrical ion-acoustic solitary waves in electronegative plasmas with superthermal electrons 

    Type: Journal Paper
    Author : پروین اسلامی; Marzieh Mottaghizadeh; Parvin Eslami
    Year: 2012
    Abstract:

    By using the standard reductive perturbation technique, a three-dimensional cylindrical

    Kadomtsev-Petviashvili equation (CKPE), which governs the dynamics of ion acoustic solitary waves

    (IASWs), is derived for small but finite...

    Propagation of solitary waves in non uniform dusty plasmas 

    Type: Journal Paper
    Author : کورش جاویدان; P. Mohammad zadeh; Kurosh Javidan
    Year: 2012
    Abstract:

    Interaction of dust acoustic solitary waves in plasmas consisting of medium disorders is investigated. Disorders and inhomogeneities of the medium are added to the equation of motion as perturbative terms through the medium parameters. The effects...

    Cylindrical and spherical electron acoustic solitary waves in the presence of superthermal hot electrons 

    Type: Journal Paper
    Author : کورش جاویدان; H.R. Pakzad; Kurosh Javidan
    Year: 2011
    Abstract:

    Propagation of cylindrical and spherical electronacoustic solitary waves in unmagnetized plasmas consisting

    of cold electron fluid, hot electrons obeying a superthermal distribution and stationary ions are investigated. The standard reductive...

    Distribution functions of electrons in the Earth and Venus ionospheres: Effects on the propagation of localized waves 

    Type: Journal Paper
    Author : مرضیه قباخلو; محمدابراهیم زمردیان; کورش جاویدان; Marzieh Ghobakhloo; Mohammad Ebrahim Zomorrodian; Kurosh Javidan
    Year: 2018
    Abstract:

    equilibrium. Propagation of small amplitude dust-ion acoustic solitary waves (DIASWs) in Earth and Venus ionospheres based on the derived distribution functions for electrons is investigated. Moreover, effects of presenting different polarity of dust grains...

    Electron acoustic waves in atmospheric magnetized plasma 

    Type: Journal Paper
    Author : حمیدرضا پاکزاد; کورش جاویدان; پروین اسلامی; HAMID REZA PAKZAD; Kurosh Javidan; Parvin Eslami
    Year: 2019
    Abstract:

    Propagation of electron acoustic solitary waves is studied in magnetized plasmas
    consisting of hot and cold electrons and stationary ions in the presence of varying magnetic
    field. We show that a space dependent magnetic field adds a...

    Solitons of the Kadomstev-Petviashvili (KP) and the modified KP equation for the dust dust acoustic solitary waves in dusty plasmas 

    Type: Conference Paper
    Author : حمیدرضا پاکزاد; کورش جاویدان; Kurosh Javidan
    Year: 2007
    Abstract:

    By using the reductive perturbation theory, the Kadomstev-Petviashvili (KP) equation in unmagnetized dusty plasmas with variable dust charge, electrons with Boltzmann distribution and nonthermal ions, is derived and the ...

    Cylindrical and spherical ion acoustic solitary waves in electron-positron-ion plasmas with superthermal electrons 

    Type: Journal Paper
    Author : کورش جاویدان; Kurosh Javidan
    Year: 2013
    Abstract:

    Propagation of cylindrical and spherical ion acoustic solitary waves in plasmas consisting of cold ions,

    superthermal electrons and thermal positrons are investigated. It is shown that cylindrical/spherical Korteweg-de-Vries equation governs...
