-state Potts ice
Mark Potts, S. A. Parameswaran, Roderich Moessner
Classical and quantum spin ice arguably provide the simplest route towards spin liquids and their emergent gauge fields. state Potts ice models have been constructed that gener…

Spin-qubit Noise Spectroscopy of Magnetic Berezinskii-Kosterlitz-Thouless Physics
Mark Potts, Shu Zhang
We propose using spin-qubit noise magnetometry to probe dynamical signatures of magnetic Berezinskii-Kosterlitz-Thouless (BKT) physics. For a nitrogen-vacancy (NV) center coupled t…

Signatures of spinon dynamics and phase structure of dipolar-octupolar quantum spin ices in two-dimensional coherent spectroscopy
Mark Potts, Roderich Moessner, Owen Benton
We study how sharp signatures of fractionalization emerge in nonlinear spectroscopy experiments on spin liquids with separated energy scales. Our model is that of dipolar-octupolar…
