Hamiltonian-Dirac Simulated Annealing: Application to the Calculation of Vortex States


A simulated annealing method for calculating stationary states for models
that describe continuous media is proposed. The method is based on the
noncanonical Poisson bracket formulation of media, which is used to construct
Dirac brackets with desired constraints, and symmetric brackets that cause
relaxation with the desired constraints. The method is applied to
two-dimensional vortex dynamics and a variety of numerical examples are
given, including the calculation of monopole and dipole vortex states.
