Relativistic degeneracy effect on propagation of arbitrary amplitude ion-acoustic solitons in Thomas-Fermi plasmas

Abdolrasoul Esfandyari-Kalejahi, Massoud Akbari-Moghanjoughi, Ehsan Saberian

Arbitrary amplitude ion-acoustic solitary waves (IASWs) are studied using Sagdeev-Potential approach in electron-positron-ion plasma with ultra-relativistic or non-relativistic deg…
