The spin-1/2 Heisenberg model on the pyrochlore lattice is an iconic frustrated three-
dimensional spin system with a rich phase diagram. Besides hosting several ordered …

Quantum loop and dimer models are prototypical correlated systems with local constraints,
which are not only intimately connected to lattice gauge theories and topological orders but …

The quantum dimer and loop models attract great attention, partially because the
fundamental importance in the phases and phase transitions emerging in these prototypical …

We revisit the phase diagram of Rokhsar-Kivelson models, which are used in fields such as
superconductivity, frustrated magnetism, cold bosons, and the physics of Josephson junction …

We consider the spin-orbital model for a magnetic system with singly occupied but triply
degenerate t 2 g orbitals coupled into a planar, triangular lattice, as would be exemplified by …

Recently, quantum dimer models have attracted a great deal of interest as a paradigm for
the study of exotic quantum phases. Much of this excitement has centered on the claim that a …

Quantum phase transitions in the two-dimensional Kugel-Khomskii model on a square
lattice are studied using the plaquette mean field theory and the entanglement …
