Modulational Stability of Envelope Soliton in a Quantum Electron-Ion Plasma in Three Dimension - A generalised Nonlinear Schr ̈odinger Equ ation in 3D
Modulational stability of envelope soliton is studied in a quantum dusty plasma in three dimension.<br>The Krylov-Bogoliubov-Mitropolsky method is applied to the three dimension plasma governing<br>equations. A generalised form of Nonlinear Schr¨odinger equation is obtained whose dispersive term<br>has a tensorial character. Stability condition is deduced abintio and the stability zones are plotted<br>as a function of plasma parametersdoi:10.36227/techrxiv.12561131.v1 fatcat:3dank5u27bgjzka52y2fezluzy
