The two-dimensional classical Ising model can be approximately implemented on a Si(100) surface, where the dimers are anisotropically coupled. In particular, the setup allows for time-dependent temperatures, where the Kibble-Zurek mechanism predicts topological defect formation while traversing the critical point at a finite rate. We numerically investigate the corresponding relaxation dynamics of a two-dimensional extended Ising model with diagonal couplings and time-dependent temperature.
