Life on Earth has made us familiar with three states of matter, viz; solid, liquid, and gaseous states. However, when a gas is heated to higher temperatures, it disintegrates into ions and electrons and the gas becomes fully or partially ionized forming a plasma state, which is the 'fourth state' of matter. The presence of massive charged dust particles in a plasma can drastically influence the dispersion and nonlinear properties of a wave. As a result, in recent years, there has been a rapidly growing interest in nonlinear phenomena (such as solitons) in dusty plasmas. A theoretical...
