Coupled Fredkin and Motzkin chains from quantum six- and nineteen-vertex models
Zhao Zhang, Israel Klich
We generalize the area-law violating models of Fredkin and Motzkin spin chains into two dimensions by building quantum six- and nineteen-vertex models with correlated interactions.…

Quantum lozenge tiling and entanglement phase transition
Zhao Zhang, Israel Klich
While volume violation of area law has been exhibited in several quantum spin chains, the construction of a corresponding ground state in higher dimensions, entangled in more than…
