Quantum dimer models
read the original abstract
These lecture notes aim to provide a self-contained, pedagogical introduction to the physics of local constraints, fractionalisation and topological liquids organised around the Rokhsar-Kivelson quantum dimer model. Topics and phenomena covered include emergent photons, SU(2) invariant spin liquids, valence-bond solids and Cantor deconfinement, along with an elementary introduction to the underlying theoretical models and methods.

Group Convolutional Neural Network for the Low-Energy Spectrum in the Quantum Dimer Model
GCNN variational states optimized with directed-loop sampling yield a 4-fold degenerate ground state for V ≤ 0.4 in the quantum dimer model, with benchmarks matching ED and QMC up to L=32.
