. The effect of electron-phonon collision frequency, exchange-correlation potential, quantum term and degenerate pressure on the nature of solitary waves in a quantum semiconductor plasma is investigated. It is observed that the width of the solitary waves change with variation of different parameters for the GaAs semiconductor. A deformed Korteweg-de Vries equation is obtained for propagation of...
We investigate the face-to-face collision between multisolitons in spin-1/2 quantum plasma. It is studied in the framework of the model proposed by Marklund et al in Phys. Rev. E76, 067401 (2007). This study is done with the help of the extended Poincare–Lighthill–Kno (PLK) method. The extended PLK method is also used to obtain two Korteweg–de Vries (KdV) equations and the phase shifts and trajectories...
