Analytic vortex solutions in an unusual Mexican hat potential
arXiv:cond-mat/9711240 · doi:10.1103/PhysRevE.56.4809
Abstract
We introduce an unusual Mexican hat potential, a piecewise parabolic one, and we show that its vortex solutions can be found analytically, in contrast to the case of the standard Psi^4 field theory.
