The precise theoretical characterization of a fractionalized phase in spatial dimensions higher than one is through the concept of ``topological order''. We describe a physical effect that is a robust and direct consequence of this hidden order that should enable a precise experimental characterization of fractionalized phases. In particular, we propose specific ``smoking-gun'' experiments to unambiguously settle the issue of electron fractionalization in the underdoped cuprates.

A theory predicts that doping a ν=2/3 fractional quantum anomalous Hall insulator with charge-2/3 anyons can drive a direct transition to a chiral topological superconductor, with a universal resistance peak, while ch...
