Deconfined criticality between an antiferromagnetic insulator and a nodal d-wave superconductor: a quantum Monte Carlo study
This study used quantum Monte Carlo simulations to investigate a quantum phase transition between an antiferromagnetic insulator and a nodal d-wave superconductor. The research found evidence for electron fractionalization at this transition, suggesting that these fractionalized excitations are central to understanding high-temperature superconductivity in cuprates.
