Bionic Coulomb phase on the pyrochlore lattice
Bionic Coulomb phase on the pyrochlore lattice
A class of three dimensional classical lattice systems with macroscopic ground state degeneracies, most famously the spin ice system, are known to exhibit "Coulomb" phases wherein long wavelength correlations within the ground state manifold are described by an emergent Maxwell electrodynamics. We discuss a new example of this phenomenon-the four …
