Fractional quantum Hall effect (FQHE) remains the most fundamental phenomenon of quantum collective states with topological characterization. It is also the most reliable platform for developing topological and geometric ideas in physics of quantum states. Topological properties of fractional quantum hall states have been studied, appreciated and satisfactorily understood since early years of the phenomena by incorporating Chern-Simons topological quantum field theories.
However, the Chern-Simons description applies in the limit in which the energy gap to all bulk excitations has been sent to infinity. It is therefore impossible, even in principle, to study the dynamics of quantum states beyond the linear response theory solely within the Chern-Simons framework. Many fundamentally important and observable properties of the phenomena are left behind in such an approximation. In recent years it had been understood that these properties are governed by geometric nature of FQH states whose global aspects are the topological properties.
The geometrical properties describe the response of the quantum states on a change of geometry. Moreover, bulk excitations are geometrically coupled to the edge states and may have nontrivial effects on the dynamics of edge modes. Therefore, for many reasons, theoretical approaches to the FQH effect that go beyond Chern-Simons theory are essential for better understanding of physics of the FQH phenomenon, and of all topological quantum states beyond QHE.
