AbstractWe point out the experimental relevance and the detection scheme of symmetry-enriched U(1) quantum spin liquids (QSLs) outside the perturbative spin-ice regime. Recent experiments on Ce-based pyrochlore QSL materials suggest that the candidate QSL may not be proximate to the well-known spin-ice regime, and thus differs fundamentally from other pyrochlore QSL materials. We consider the possibility of the π-flux U(1) QSL favored by frustrated transverse exchange interactions rather than the usual quantum spin ice. It was previously suggested that both dipolar U(1) QSL and octupolar U(1) QSL can be realized for the generic spin model for the dipole-octupole doublets of the Ce3+ local moments on the pyrochlore magnets Ce2Sn2O7 and Ce2Zr2O7. We explain and predict the experimental signatures, especially the magnetic field response of the octupolar π-flux U(1) QSL. Fundamentally, this remarkable state is a mixture of symmetry enrichments from point-group symmetry and from translational symmetry. We discuss the relevant experiments for pyrochlore U(1) QSLs and further provide some insights to the pyrochlore Heisenberg model.
