For vortons, R is a cutoff in Eperp.
Outside we just guess field=sqrt{n}.

E = 2piR Eperp.
\eq
Commented out the part about R being an IR cutoff; should check it.
Total quantities = 2piR * linear densities
Req
Angular momentum
Min E wrt f1, f2, R, all else fixed.
Minimization & some obvious dependencies.
Contrastingly some dependencies are not easy to understand.
