Tunable deconfined quantum criticality and interplay of different valence-bond solid phases

Zhao Bowen¹, Takahashi Jun^{2, 1}, Sandvik Anders W.^{1, 2, †}

Dimer patterns of different types of vortices in (a), (b) the cVBS phase and in (c)–(f) the sVBS phase. In (a), (b), (c), (e) the dimer patterns require an unpaired spin (spinon), while in (d), (f) no spinon is induced.
