Such parent states provide a unified theory of previously studied fractionalized states: their descendants include insulating and conducting states with neutral spin $$S$$=1/2 fermionic spinons, and states with spinless fermionic charge carriers. We illustrate these ideas on the honeycomb lattice, with field theories of such states and their phase transitions.
