Institute for Quantum Matter at Johns Hopkins University, Baltimore, MD 21218, USA(Dated: August 6, 2012)Topological insulator quantum wells with induced attractive interactions between electrons arecandidate systems for the realization of novel vortex lattice states with time-reversal symmetry,and incompressible quantum vortex liquids with fractional excitations. We analyze the competi-tion between different pairing channels stimulated by the superconducting proximity effect in thesequantum…

TLDR
An effective topological Landau-Ginzburg theory is constructed that describes general SU(2) incompressible quantum liquids of strongly correlated particles in two spatial dimensions and mainly focuses on fractional topological insulators with time-reversal symmetry.
