• Order and quantum phase transitions in the cuprate superconductors (2002, methodology): “This analysis of a model with purely short-range interactions also found a phase separation instability at small values of δ (Sachdev and Read, 1991), whose importance had been emphasized by others (Bang et al., 1991; Emery et al., 1990) on different grounds.”
• Prediction of Toric Code Topological Order from Rydberg Blockade (2020, background): “Third, there is a remarkable link between superconductivity and Z2 quantum spin liquids [12–18]—while the fermion f can be associated with Bogoliubov quasiparticles, the e, m excitations are related to the superconductor vortices.”
