Minimal Potentials with Very Many Minima
arXiv:cond-mat/9904190 · doi:10.1103/PhysRevLett.84.2285
Abstract
We demonstrate, by construction, that simple renormalizable matrix potentials with S_N, as opposed to O(N), symmetry can exhibit an exponentially large number of inequivalent deep local minima.
