10. The transition from superconductor to fractionalized insulator at zero-temperature can be recast through a duality transformation, in terms of the proliferation and condensation of (Formula presented) vortices. On a lattice with (Formula presented) bosons per unit cell, these vortices see (Formula presented) flux through each plaquette. As the vortices proliferate, this flux frustrates vortex motion, which we expect to lead to spontaneous breaking of translational or rotational symmetries.

13. A well-studied case of this is superfluid (Formula presented), where due to interactions, even at zero temperature the condensate density (Formula presented) is much less than the total density n.
