Dynamical Signatures of Fractionalization in Dipolar-Octupolar Quantum Spin Ice

Explore the intricacies of multipolar quantum spin ice states in a 21-minute conference talk delivered at the Workshop on "Spin-Orbit Entangled Quantum Magnetism" held at the Erwin Schrödinger International Institute for Mathematics and Physics. Delve into the theoretical analysis of quantum spin ice states in systems where Ce3+ ions carry dipolar-octupolar moments, such as Ce2Zr2O7 and Ce2Sn2O7. Examine the comparison between theoretical results of dynamical spin structure factors and recent neutron scattering experiments. Discover how the dynamical spin structure factor computed for the pi-flux quantum spin ice state exhibits clear signatures of fractionalization and aligns with recent polarized neutron scattering experiments. Gain insights into the potential realization of three-dimensional quantum spin liquids with emergent gauge fields in magnetic insulators featuring higher-rank multipolar moments due to spin-orbit coupling and local crystal-electric-field symmetry.
