RISAnalytical formulation for soliton-potential dynamics
An analytical model for the soliton-potential interaction is presented by constructing a collective coordinate
for the system. Most of the characters of the interaction are derived analytically while they are ...

Interaction of Topological solitons with defects: Collective coordinate method
By including a potential into the flat metric, we study the interaction of sine-Gordon soliton with different potentials. We will show numerically that while the soliton-barrier system shows fully classical behaviour, the ...
Collective coordinate variable for soliton-potential system in sine-Gordon model
A collective coordinate variable for adding a space dependent potential to the sine-Gordon model is presented. Interaction of solitons with a delta function potential barrier and also a delta function potential well is ...
Cylindrical and spherical ion acoustic solitary waves in electron-positron-ion plasmas with superthermal electrons
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 ...
Modulational instability of dust ion acoustic waves in dusty plasmas with superthermal electrons
The propagation of dust ion acoustic waves is studied in plasmas composed of superthermal distributed
electrons and stationary dust particles. The nonlinear Schrödinger equation is derived using the reductive ...
Ion acoustic solitary waves in electron-positron-ion plasmas with q-nonextensive electrons and high relativistic ions
Propagation of small amplitude ion acoustic solitary waves in plasmas containing q-nonextensive electrons,
thermal positrons and high relativistic ions is addressed in this paper. Our results show that the Korteweg-de ...
Propagation of solitary waves in non uniform dusty plasmas
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 ...
Cylindrical and spherical electron acoustic solitary waves in the presence of superthermal hot electrons
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. ...
Solitary waves in dusty plasmas with variable dust charge and nonthermal ions
Dust acoustic solitary waves have been studied in dusty plasma consisting of nonthermal ions, electrons and variable charge dust grains. It is shown that amplitude of solitary waves of Kadomstev-Petviashvili equation becomes ...
