Abstract:

Quantum spin ice (QSI) is a lattice spin-model realization of the full-fledged quantum electrodynamics including photons, electric charges and magnetic monopoles. As one of the most interesting quantum spin liquids, a significant amount of experimental and theoretical investigation has been done in this field. I will present an overview of the quantum spin ice physics and also discuss our recent ongoing work on how in the so-called dipole-octupole QSI, one can experimentally have clean control of the dynamics of its emergent QED, including transition between different symmetry-enriched phases, tuning the dispersion of photons and fine-structure constants etc. All of this can be achieved in one of the simplest experiments — turning on the external magnetic field in the right direction.
