Monte Carlo Minimization of the Higgs-Landau Potentials
We propose a Monte Carlo algorithm to search for the boundary points of the orbit space which is important in determining the symmetry breaking directions in the Higgs potential and the Landau potential. Our algorithm is robust, efficient and generally applicable. We apply the method to the Landau potential of the $d-$wave abnormal superconductor.
