Vortices in the XY model



it T mag   fps
Monte-Carlo simulations of spins dynamics in the XY magnetic model. Similar to the Ising model spins with different orientation φ are painted in different colors Hue(φ/2π). Vortices and anti-vortices correspond to the singular points (defects) where all colors meet together. For T = 0.03 "hot" (random) spins are frozen in correlated clusters. You can watch vortices and anti-vortices formation and annihilation. Set in the T field T = 0.003 to freez spins.
