Acoustic solitary waves and Sagdeev potential triple roots

Manfred Armin Hellberg, Thomas Kisandi Baluku and Frank Verheest UGent (2010) AIP Conference Proceedings. 1302. p.50-60
abstract
Both KdV theory and the standard pseudopotential theory require that solitons and double layers be explicitly super-acoustic, with the pseudopotential psi(phi,M) having a maximum at the origin. Recent studies of a variety of different three-component plasmas have shown that they may support finite amplitude solitons at the true acoustic speed of the plasma configuration, M-s. These are associated with triple roots of the Sagdeev potential, and the usual soliton condition is replaced by psi ''(0,M) <= 0. Sagdeev potentials for speeds marginally greater than M-s then represent solitons of both polarities, one whose amplitude vanishes at M-s (KdV-like), while the other is necessarily finite at M-s ('nonKdV-like'). Such coexistence regions have been observed to be linked to a critical plasma compositional parameter value for which psi''' (0,M-s) = 0.
