Abstract:
Quantum spin ice offers an ideal laboratory for emergent dual quantum electrodynamics, where monopole charges of magnetic moments play a role of electric charges in usual quantum electrodynamics, except that the charges are dual to each other. Candidate materials include magnetic rare-earth pyrochlore oxides such as Pr2Zr2O7, Tb2Ti2O7, and Yb2Ti2O7, as well as the A-site deintercalated iridium spinel oxide Ir2O4. Here, we review recent works on possible controls of the emergent quantum electrodynamics by means of an applied electric field. In particular, we explain how a dual Hall transport phenomenon of the magnetic monopoles and monopole supercurrent through two quantum spin ice ferromagnets occur under the electric field.
