We construct an effective topological Landau–Ginzburg theory that describes general SU(2) incompressible quantum liquids of strongly correlated particles in two spatial dimensions. This theory characterizes the fractionalization of quasiparticle quantum numbers and statistics in relation to the topological ground-state symmetries, and generalizes the Chern–Simons, BF (‘background field’) and hierarchical effective gauge theories to an arbitrary representation of the SU(2) symmetry group. We…

Correlation effects in two-dimensional topological insulators

This article reviews progress on the topic of electronic correlation effects in the two-dimensional case, with a focus on systems with intrinsic spin-orbit coupling and numerical results.



Time-reversal symmetric hierarchy of fractional incompressible liquids

We provide an effective description of fractional topological insulators that include the fractional quantum spin Hall effect by considering the time-reversal symmetric pendant to the topological

Holographic fractional topological insulators in 2+1 and 1+1 dimensions

We give field theory descriptions of the time-reversal invariant quantum spin Hall insulator in 2 + 1 dimensions and the particle-hole symmetric insulator in 1 + 1 dimensions in terms of massive

Fractional topological insulators.

Generalizations of two-dimensional topological insulators which can be realized in interacting, time reversal invariant electron systems, which contain excitations with fractional charge and statistics in addition to protected edge modes are analyzed.

Chiral Rashba spin textures in ultracold Fermi gases

Spin-orbit (SO) coupling is an important ingredient in many recently discovered phenomena such as the spin-Hall effect and topological insulators. Of particular interest is topological

Topological insulators and superconductors

Topological insulators are new states of quantum matter which cannot be adiabatically connected to conventional insulators and semiconductors. They are characterized by a full insulating gap in the


We introduce a 2+1 dimensional lattice model, S0, of N complex scalars coupled to a compact U(1) gauge field as a description of quantum fluctuations in SU(N) antiferromagnets. Duality maps are used
