Electron acoustic dressed soliton in quantum plasma

The nonlinear propagation of electron-acoustic waves in three components unmagnetized dense quantum plasma consisting of inertially cold electrons, inertia-less hot electrons and immobile ions is investigated using a one dimensional quantum hydrodynamic model. Using the standard reductive perturbation technique the Korteweg–de Vries equation is derived. The higher order inhomogeneous differential equation is obtained for the dressed soliton. The dynamical equation for dressed soliton is solved using renormalization method and the particular solution is obtained by using the method developed by Chatterjee et al. (Phys Plasmas 16:072102, 2009). (author)
