The Hydrodynamical Limit of Quantum Hall system
D. Sreedhar Babu, R. Shankar, M. Sivakumar
Abstract
We study the current algebra of FQHE systems in the hydrodynamical limit of small amplitude, long-wavelength fluctuations. We show that the algebra simplifies considerably in this limit. The hamiltonian is expressed in a current-current form and the operators creating inter-Landau level and lowest Landau level collective excitations are identified.
