The Kitaev Model

Caption

The vertices of this honeycomb network represent sites with two possible spin states. One intriguing property of this model is that a magnetic pulse applied in the left shaded region causes spin changes in the right shaded regions but not in the middle portion. Until now, the mechanism by which the spin perturbation crossed the middle region was unclear.
