Nature of problem:The Ginzburg-Landau-equations are solved for a straight single fluxoid containing an (integer) number q of flux quanta, starting from an approximate solution which has to be submitted by the user if q > 1. | ||

Solution method:An iteration procedure is applied based on successive linearizations of the Ginzburg-Landau-equations. In each iteration step, the system of linearized differential equations is solved by a finite-difference- technique with small intervals near the core and big intervals far outside. The line-energy of the fluxoid is calculated. | ||

Running time:If one takes about one hundred lattice points ranging from a radial distance r=0 to about r=7 (reduced units of the Ginzburg-Landau-theory), and if an absolute error of the modulus of the order parameter and of the magnetic field of less than 10**-3 is required, typical running times on the Telefunken TR4 are about 3 minutes, including compilation time (about 1 minute). |
