Tunable deconfined quantum criticality and interplay of different valence-bond solid phases |
Results near the cVBS–AFM transition for h = 0, 0.1,0.2, and 0.25, from left to right as indicated. Squared AFM order parameter are shown in panels (a)–(d) and the corresponding Binder cumulants in (e)–(h). Results for different system sizes are color coded as indicated in the legends in (h). In the cVBS phase for h = 0.25 the simulations again some times get trapped in states with defects, as in Fig. |
