Effective Fractional Hall Effect with Pseudo-Photons

چکیده
At variational level in the framework of dimensional reduced Ue(1) × Ug(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 such that the role of the collective electric and magnetic fields are swapped in relation to the usual models. We show that the model contains both magnetic vortexes due to the internal photons (interpreted as quasiparticles) 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 σ̂H 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 naturally justified due to the pseudo-photon being a ghost field (or phantom). Furthermore, in this framework, 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.

Effective vector-field theory and long-wavelength universality of the fractional quantum Hall effect
We report on an effective vector-field theory of the fractional quantum Hall effect that takes into account projection to Landau levels. The effective theory refers to neither the compositeboson nor composite-fermion picture, but properly reproduces the results consistent with them, thus revealing the universality of the long-wavelength characteristics of the quantum Hall states. In particular,...
متن کاملConformal Field Theory and the Fractional Quantum Hall Effect
We examine the application of c = 1 conformal field theory to the description of the fractional quantum Hall effect (FQHE). It is found that the Gaussian model together with an appropriate boundary condition for the order parameter furnishes an effective theory for the Laughlin type FQHE. The plateau formation condition corresponds to taking the chiral portion of the theory. e-mail: scip1005@nu...
متن کاملMatrix Effective Theories of the Fractional Quantum Hall effect
The present understanding of nonperturbative ground states in the fractional quantum Hall effect is based on effective theories of the Jain “composite fermion” excitations. We review the approach based on matrix variables, i.e. D0 branes, originally introduced by Susskind and Polychronakos. We show that the Maxwell-Chern-Simons matrix gauge theory provides a matrix generalization of the quantum...
