solitons — 2 discussions

In nonlinear classical field theories that admit localized or topological solutions (for example, Skyrme-type or Faddeev–Skyrme-type models), what mathematical and numerical evidence is normally considered sufficient to distinguish a genuinely stable localized solution from a stationary...

I've been studying vortex solutions in SU(N) gauge theories with adjoint scalars. The standard problem is that vortons (closed vortex loops) are unstable and collapse due to line tension. However, I've found that including a DBI-type term (similar to those in string theory effective actions)...
