Finite density of anyonic excitons in bilayer Laughlin states at total filling 2/3 yields an exciton superfluid with specific bulk topological order, edge spectrum, and stiffness scaling as |δν|^{1/2} near Halperin (112) transitions.
Numerical work on ν=1/2 bosonic flat-band models reports a vestigial gapless CDW between FCI and finite-momentum SS on checkerboard lattice and FCI-Solid I-Solid II transitions on honeycomb lattice, both driven by roton-mode softening.
