Quantum Ion-Acoustic Waves
The quantum hydrodynamic model is applied to ion-acoustic waves in quantum plasmas. The corresponding linear dispersion relation is found, as well as a modified Korteweg–de Vries equation for weakly nonlinear solutions. Quantum effects are shown to enlarge the associated solitary wave solutions width. Fully, nonlinear traveling wave solutions are investigated.
