Implication

Theoretical modeling reveals compressive and rarefactive soliton collision dynamics in degenerate quantum plasma, highlighting wave behavior in dense astrophysical and laser environments.

Key Points

To analyze the collision dynamics, structural changes, and phase shifts of head-on and overtaking multi-ion-acoustic solitons in unmagnetized quantum plasma with arbitrary degenerate electrons.
Derived two-sided Korteweg–de Vries equations and phase shifts using the extended Poincaré-Lighthill-Kuo perturbation method.
Applied the Hirota bilinear approach to analyze multi-soliton overtaking collisions and calculate associated phase shift expressions.
Compressional solitons propagate at supersonic speeds when quantum diffraction satisfies H < 2, whereas rarefactive solitons travel at subsonic speeds when H > 2.
Head-on collision creates a transient nonlinear structure with higher amplitude in the interaction region than individual interacting solitons.
Soliton profiles and phase shifts vary systematically in response to alterations in quantum diffraction and electron fugacity parameters.
