Spin ices, magnetic analogue of the proton-disordered state of common water ice, have been found to be an examplar of high magnetic frustration in three dimensions. Significant progress has been made over the past fifteen years in understanding so-called "classical" spin ice systems, as realized experimentally in Ho2M2O7 and Dy2M2O7 (M=Ti,Sn,Ge) rare-earth pyrochlore oxides. In the past four years, interest from theorists and experimentalists has turned towards spin ice variants in which quantum fluctuations are no longer negligible as thought to be the case in the classical compounds. These materials are generically referred as quantum spin ice (QSI). It is expected that the effective field theory describing QSI systems is akin to 3+1 lattice QED, with the low-energy excitations of these materials characterized by gapped "electric" (e.g. spinon) excitations and "gauge charge" (e.g. monopole) energy excitations along with a gapless "photon". Quantum spin ice may prove a promising candidate to identify a quantum spin liquid state of matter in three (spatial) dimensions described by a reasonably well-controlled theory and, if ultimately evinced experimentally, a possible textbook example of strong emergence. This workshop will bring together experimentalists and theorists expert in the field to discuss the experimental, theoretical and numerical challenges and promises that surround the search for a quantum spin liquid state in QSI candidate models and materials.
