Abstract

At variational level in the framework of dimensional reduced 'U_e(1)\times U_g(1)' electromagnetism it is considered an anyon Landau-Ginzburg Chern-Simons model for the fractional Hall effect. The collective gauge fields are due to pseudo-photons (...). We show that the model contains both magnetic vortexes due to the internal photons (interpreted as quasi-particles) and electric vortexes due to the internal pseudo-photons (interpreted as quasi-holes) that account for the anyon quantized magnetic flux and fractional electric charges, respectively. The effective magnetic flux is the only effective effect attributed to the standard internal photon which ensures compatibility between the pseudo nature of Laughlin's wave functions and macroscopical parity 'P' and time-inversion 'T' symmetries. In this way the model preserves these symmetries both at variational level and at the level of the electromagnetic equations. In particular holds the usual fractional Hall conductances with the Hall conductance '\hat{\sigma}_H' being a pseudo-scalar consistently with the electric Hall current equation. The negative energy contribution of quasi-holes to the Laughlin's wave function (...) is justified and the quantization of magnetic flux is directly equivalent to the Dirac's quantization condition applied to the coupling constants, or fundamental unit charges 'e' and 'g'. If our framework proves to be correct, quantization of magnetic flux may be the most direct evidence for Dirac's quantization condition. Our results also indicate that pseudo-photons electric vortex may give a theoretical justification for the electric potential between layers of bi-layer Hall systems.
