Fig. 3: Equilibrium real-space vison correlations.
From: Correlation holes and slow dynamics induced by fractional statistics in gapped quantum spin liquids
Connected vison correlator Cρ(r), r = (x, y), at two temperatures (marked for reference also in Fig. 2), a, c T1/ts = 2.3 10−3 and b, d T2/ts = 9.6 10−3. a, b correspond to the MC data, while c, d are the predictions of the empty disc model. As temperature is increased, the typical size of the vison-depleted patch shrinks and the length scale over which the visons are correlated is correspondingly reduced. The calculations were performed for a system of size L2 = 202 satisfying periodic boundary conditions.
