| Title: | Three Stringy Realizations of Fractional Quantum Hall Effect |
| Date (JST): | Thu, Feb 26, 2009, 15:30 - 17:00 |

| Abstract: | I will present three stringy realizations of fractional quantum Hall effect (FQHE), and compute Hall conductivity holographically. The first model studies edge states in FQHE using supersymmetric domain walls in N=6 Chern-Simons theory. The second model gives a holographic dual to the pure U(N)_k Chern-Simons theory using a D3-D7 system. The third model is the first string theory embedding of hierarchical FQHEs, using IIA string on C^2/Z_n. |
