Fractional Quantum Hall Effect via Holography: Chern-Simons, Edge States, and Hierarchy

Fujita, Mitsutoshi, Li, Wei, Ryu, Shinsei et al.

Understand

We present three holographic constructions of fractional quantum Hall effect (FQHE) via string theory.

  • The first model studies edge states in FQHE using supersymmetric domain walls in N=6 Chern-Simons theory.
  • We show that D4-branes wrapped on CP^1 or D8-branes wrapped on CP^3 create edge states that shift the rank or the level of the gauge group, respectively.
  • These holographic edge states correctly reproduce the Hall conductivity.
