Title The Role of the Massless Phantom Term in the Stability of a NonTopological Soliton Solution
Type Article

Researchers Mohammad Mohammadi (First researcher)


We intend to introduce classically a special Lagrangian density in such a way that, frstly, it leads to a special non-topological solitary wave solution, secondly, the stability of that is guaranteed properly, and thirdly, its dominant dynamical equations reduce to the standard nonlinear Klein–Gordon equations. For these purposes, we have to consider a new term in the Lagrangian density, whose role is like a massless phantom that surrounds the special solitary wave solution and resists any change in its internal structure.
