Probing Flat Band Physics in Spin Ice Systems via Polarized Neutron Scattering
Published in Physical Review Letters, 2022
In this work we studied the use of polarized neutron scattering to expose the correlations of flat band modes in a frustrated magnet. In particular we explained the “flat NSF”, i.e. the featureless non-spin-flip scattering cross section, of nearest-neighbor spin ice, and demonstrated how it attains features in dipolar spin ice.
