| Summary:
We describe a Higgs mechanism for the partially massless graviton. In order
to do so, we first construct a covariant fracton-like effective field theory on
de Sitter space that linearly realizes a dipolar shift symmetry. The global
symmetry of this theory can be gauged by coupling it to a partially massless
spin-2 gauge field. When the fractonic matter condenses, the dipole symmetry is
spontaneously broken, the resulting Goldstone mode is a galileon and the
partially massless graviton combines with this mode and becomes fully massive.
At long distances, the phenomenology of this theory is captured by a
quasi-topological field theory and displays many features analogous to those of
the superconducting phase in electromagnetism, including gapless edge modes and
persistent currents. We also describe the generalization to higher spins.
