In this paper, steady bifurcation and solitons in relativistic laser plasmas interaction are investigated. At first, a new coupled equation for wake wave and the circularly polarized transversal electromagnetic wave is derived. It is a Hamiltonian sy

Hysteresis is a common phenomenon in a type of nonlinear waves. Corresponding to the negative tangential branch of a hysteretic curve the steady wave solutions are unstable due to saddle instability; such a saddle steady wave (SSW) is a moving saddle

With the aid of Rose–Hindmarsh (RH) model, the effects of additive Gaussian white noise (GWN), Ornstein–Uhlenbeck noise (OUN) and quasi-monochromatic noise (QMN) on neurons have been numerically studied and compared. According to the dynamic beha

With two-temperature ions in dusty plasma, the effects of variable dust charge on small-amplitude dust-acoustic solitons and large-amplitude dust-acoustic solitary waves are investigated. It is found that both compressive and rarefactive solitons (an

For a weak ion flow coupling with collective dusty-acoustic waves, it is demonstrated that there exists an attractive potential necessary for the formation of dusty plasma crystals with the characteristic spacing of potential minima less than plasma

The effect of dust charging and the influence of its adiabatic variation on dust-acoustic solitary waves is further studied. A more reasonable normalization for the dust velocity by the dust-acoustic speed is adopted, which varies self-consistently w

The dynamical behavior of a Korteweg-de Vries (KdV) system driven by a solitary wave is studied. A hierarchy of hystereses, i.e. multistability, for the steady wave momenta is found in the system. Winding number bifurcation occurs for the steady wave

A new transition mechanism into spatiotemporal chaos is reported. In a system with hysteresis weconsider a steady wave that is unstable due to a saddle node. If it is taken as a carrier wave one can finda new steady wave combined by the carrier and

A new kind of solitary waves is found coexisting with bistable steady waves in driven drift-wave system. The energies of these steady waves distribute in the gap between that of the bistable steady waves. The gap state is a combined result of the car
