Abstract

In the present paper, we utilize both the Vasyliunas and Shamel models for electrons to explore the formation of compressive and rarefactive solitary waves in plasma laser-created. The distribution called Vasyliunas-Shamel distribution allows observation of the effects of the usual enhanced non-Maxwellian tail with an excess of superthermal particles (Vasyliunas distribution) while including the trapped particles in the low energy part of the distribution (Shamel distribution). We examined the behavior of the K-dV-like equation by using the reductive perturbation technic. A solitary wave solution was presented and its dynamics discussed. It is found that increasing superthermality affects the soliton shape while particle trapping leads to a stronger nonlinearity.
