Geometry and physics of Quantum Hall states on Riemann surfaces
Quantum Hall states are N-particle wave functions, successfully describing the fractional quantum Hall effect (QHE). It was understood early on, that much can be learned about QHE when QH states are considered on a Riemann surface. We define QH states on a Riemann surface and study their topological degeneracy, adiabatic transport of QH states on moduli spaces and geometric responses to the metric, magnetic field, etc. -- for the large number of particles N. We will discuss the Hall viscosity, Hall central charge and topological phases from this point of view.
