Hausdorff dimension, anyonic distribution functions, and duality | | Wellington da Cruz
; | | Date: |
28 Oct 1998 | | Subject: | Mesoscopic Systems and Quantum Hall Effect | cond-mat.mes-hall hep-th | | Abstract: | We obtain the distribution functions for anyonic excitations classified into equivalence classes labeled by Hausdorff dimension $h$ and as an example of such anyonic systems, we consider the collective excitations of the Fractional Quantum Hall Effect (FQHE). We also introduce the concept of duality between such classes, defined by $ ilde{h}=3-h$. In this way, we confirm that the filling factors for which the FQHE were observed just appears into these classes and the internal duality for a given class $h$ or $ ilde{h}$ is between quasihole and quasiparticle excitations for these FQHE systems. Exchanges of dual pairs $(
u, ilde{
u})$, suggests conformal invariance. A connection between equivalence classes $h$ and the modular group for the quantum phase transitions of the FQHE is also obtained. A $eta-$function is also defined for the complex conductivity which embodies the $h$ classes. | | Source: | arXiv, cond-mat/9810381 | | Services: | Forum | Review | PDF | Favorites | |
