On the origin of duality in the quantum Hall system
We discuss the possible origin of the duality observed in the quantum Hall current-voltage characteristics We clarify the difference between ``particle-vortex{''} (complex modular) duality, which acts on the full transport tensor, and ``charge-flux{''} ({''}real{'&...

| Sumario: | We discuss the possible origin of the duality observed in the quantum Hall current-voltage characteristics We clarify the difference between ``particle-vortex{''} (complex modular) duality, which acts on the full transport tensor, and ``charge-flux{''} ({''}real{''}) duality, which acts directly on the filling factor. Comparison with experiment strongly favors the form of duality which descends from the modular symmetry group acting holomorphically on the complexified conductivity (C) 2010 Elsevier B V All rights reserved |
