Abstract
We explain the field-induced chiral phenomena in inhomogeneous superconductivity and perform a computational simulation to demonstrate such phenomena on the basis of the Ginzburg–Landau equation for the inhomogeneous interface superconductivity of a eutectic system. Field-induced chiral phenomena occur because of the paramagnetic coupling of an intrinsic magnetization with an external magnetic field. Applying a magnetic field to a non-chiral state leads to a field-induced chiral transition with the generation of a paramagnetic chiral current. Numerically solving the aforementioned equation yields converged solutions and output numerical data obtained through an iterative process. The actual time for this calculation can be distinctly reduced through acceleration via code optimization that is suitable for vector parallelization. Reducing the calculation time makes it possible to extend the simulation to lower temperatures where the inhomogeneous superconductivity spreads to a greater distance from the interface.
