Scaling dimensions of higher-charge monopoles at deconfined critical points (2015)
Journal Article
Sreejith, G., & Powell, S. (2015). Scaling dimensions of higher-charge monopoles at deconfined critical points. Physical Review B, 92(18), Article 184413. https://doi.org/10.1103/PhysRevB.92.184413

The classical cubic dimer model has a columnar ordering transition that is continuous and described by a critical Anderson–Higgs theory containing an SU(2)-symmetric complex field minimally coupled to a noncompact U(1) gauge theory. Defects in the di... Read More about Scaling dimensions of higher-charge monopoles at deconfined critical points.

Ferromagnetic Coulomb phase in classical spin ice (2015)
Journal Article
Powell, S. (2015). Ferromagnetic Coulomb phase in classical spin ice. Physical Review B, 91(9), Article 094431. https://doi.org/10.1103/PhysRevB.91.094431

Spin ice is a frustrated magnetic system that at low temperatures exhibits a Coulomb phase, a classical spin liquid with topological order and deconfined excitations. This work establishes the presence of a Coulomb phase with coexisting ferromagnetic... Read More about Ferromagnetic Coulomb phase in classical spin ice.
