Multicritical deconfined quantum-criticality and Lifshitz point of a helical valence-bond phase
Bowen Zhao, Jun Takahashi, Anders W. Sandvik
The square-lattice - model hosts a deconfined quantum phase transition between antiferromagnetic and dimerized (valence-bond solid) ground states. We here study two d…

Tunable deconfined quantum criticality and interplay of different valence-bond solid phases
Bowen Zhao, Jun Takahashi, Anders W. Sandvik
We use quantum Monte Carlo simulations to study a quantum spin model with competing multi-spin interactions. We find a quantum phase transition between a columnar valence-b…

Valence-bond solids, vestigial order, and emergent SO(5) symmetry in a two-dimensional quantum magnet
Jun Takahashi, Anders W. Sandvik
We introduce a quantum spin-1/2 model with many-body correlated Heisenberg-type interactions on the 2D square lattice, designed to host a plaquette valence-bond solid (PVBS) ground…
