The book deals with some of the problems of solitary wave propagation in quantum plasma. The physics of quantum plasma is a recently growing field of interest and has the potential to provide solution to many of the problems associated with the stabilizing of plasma. Many astrophysical and laboratory produced plasmas show quantum properties due to their high density and the resulting overlapping of de Broglie waves of individual particles. With the pioneering works using Quantum hydrodynamic (QHD) model by Haas, Manfredi, Shukla and some others the physics of quantum plasma has become more easy to explore and meaningful to interpret. Hope the reader will find the book interesting.
