Coulombic antiferromagnet in spin-1/2 pyrochlores with dipole-octupole doublets

Abstract

Exotic state of matter could coexist with conventional orders such that the gauge fields and fractionalized excitations could prevail in a seemingly ordered state. We explore the Coulombic antiferromagnet in the spin-1/2 pyrochlores with dipole-octupole doublets. This fractionalized antiferromagnetic state carries both antiferromagnetic order and emergent quantum electrodynamics with the gapless gauge photon and fractionalized quasiparticles. We explain the characteristic physical properties including the thermodynamics and the dynamics of this exotic state. This includes for example the anomalously large $T^3$ specific heat and the broad spinon continuum in the inelastic neutron scattering. We discuss the experimental and material's relevance and expect this work to inspire interests in the search of exotic physics among the ordered magnets.
