“…To maintain the stability of the soliton structure, it is crucial to balance dispersion and non-linearity with a specific amplitude. In order to determine the conditions for the existence of Double-layer (DL) solutions for the equation (15), it is imperative to investigate the comprehensive criteria related to Segdeev pseudopotential. This investigation ensures the presence of a solitary wave, which is determined by a set of conditions, the first of which is,…”

“…Indeed, under specific conditions, dust particles within a dusty plasma can give rise to double layersstructures with substantial amplitude sustained by the delicate balance between nonlinearity and dispersion effects. Various techniques, including Sagdeev pseudopotential approach [15], have been employed to examine the formation and characteristics of these double layers in dusty plasmas [16]. The temperature of both the dust particles and the ion beam emerges as a significant factor influencing the region where double layers exist.…”

The investigation focuses on examining the characteristics of dust acoustic double-layers (DA-DLs) in the presence of adiabatically trapped-nonextensive ions featuring Tsallis-Gurevich distribution. Indeed, the ion-density and pseudo-potential expressions are formulated in terms of transcendental functions, allowing for a detailed analysis of Dust Acoustic Double Layers associated with complex plasmas in the presence of non-extensive adiabatically trapped ions. The study then delves into the impact of background ion nonextensivity on key DA-DLs properties. The findings reveal that our plasma model can exhibits both compressive and rarefactive DA-DLs, depending on the nonextensive parameter q. Also, the results indicate that in both sub-sonic and supra-sonic scenarios, the amplitude of the DA-DLs structure rises as the nonextensive parameter decreases. Additionally, it is observed that, for a constant value of the nonextensive parameter q, the amplitude of the DA-DLs structure increases with higher Mach numbers. This investigation, prompted by observations in space and laboratory plasmas containing non-Maxwellian particles alongside trapped particles, has the potential to complement and offer fresh insights into previous works on solitary waves in plasma.
