Polarization Analysis of the Dynamic Quantum Spin Ice Correlations in the GroundState of a Pyrochlore Magnet
The rare-earth pyrochlore magnets, R2B2O7, continue to attract great interest as they can combine quantum magnetism with geometrical frustration due to the architecture of the crystal sub-lattice that the magnetic rare-earth ions reside on. The corner-sharing tetrahedral geometry of this sub-lattice allows for the possibility of strong magnetic frustration and the typical effect of this is the promotion of exotic magnetic ground states over conventional ordered ground states. This family of magnetic materials is responsible for many quantum spin liquids. This proposal focuses on the rare type of quantum spin liquid called "quantum spin ice" (QSI) with associated emergent quantum electrodynamics and exotic excitations that behave like photons and monopoles (both electric and magnetic). We've reported inelastic measurements on Ce2Zr2O7 that give compelling evidence for a QSI ground state in this material and are proposing the first (to our knowledge) polarization analysis of the diffuse magnetic scattering arising from an integration of the low-energy excitations present in the QSI phase.
