Phase transitions and remnants of fractionalization at finite temperature in the triangular lattice quantum loop model
Xiaoxue Ran, Sylvain Capponi, Junchen Rong +2
The quantum loop and dimer models are archetypal correlated systems with local constraints. With natural foundations in statistical mechanics, they are of direct relevance to vario…

Symmetrizing the Constraints -- Density Matrix Renormalization Group for Constrained Lattice Models
Ting-Tung Wang, Xiaoxue Ran, Zi Yang Meng
We develop a density matrix renormalization group (DMRG) algorithm for constrained quantum lattice models that successfully {\it{implements the local constraints as symmetries in t…
