Determine the QSL ground state of a dipole-octupole pyrochlore Ce2Zr2O7
In the case of the Ce-based pyrochlores with the dipole-octupole doublet, the ground state can support two distinct symmetry-enriched U(1) quantum spin liquid (QSL): a dipolar QSL and an octupolar QSL, distinguished by the roles of the dipole and octupole components in each phase. Ce2Zr2O7 is a rare example of a quantum spin liquid candidate that may have an octupole doublet ground state similar to Ce2Sn2O7. Recent studies claim that Ce2Zr2O7 sits right on the boundary of dipolar QSL and octupolar QSL. A neutron polarization analysis on the spin excitation continuum will conclusively determine if these excitations are associated with electron fractionalization. For any local moment magnetism, spin waves and spin glass excitations should only have a transverse component, while fractionalization of octupolar interaction should instead have a longitudinal component, thus nailing down the origin of the QSL state.
