Order out of a Coulomb phase and Higgs transtion: frustrated transverse interactions of Nd2Zr2O7

J. Xu, Owen Benton, A. T. M. N. Islam +3

The pyrochlore material Nd${}_2$Zr${}_2$O${}_7$ with an "all-in-all-out" (AIAO) magnetic order shows novel quantum moment fragmentation with gapped flat dynamical spin ice modes. The par…
