| Abstract: | this paper introduces the fast Fourier transformation and its application in volume product, and the extension of fast Fourier transformation from periodic boundary condition to open boundary condition. We applied the extended fast Fourier transformation into the simulation of spin dynamics in condensed matter. The conclusion is that the application of fast Fourier transformation can greatly accelerated the simulation. |
