Abstract:Recent experiments on the dipolar-octupolar pyrochlore compound Ce2Zr2O7 indicate that it may realize a three-dimensional quantum spin liquid (QSL). In particular, the analyses of available data suggest that the system is in a region of parameter space, where the so-called π-flux U (1) octupolar quantum spin ice (QSI) with an emergent photon could be realized. On the other hand, because the system is far from the perturbative classical spin ice regime, it is unclear whether the quantum ground state is primaril… Show more
