B84 arXiv Field Theories of Condensed Matter Physics - The Hall conductivity that has been obtained in Ref appears to be formally identical to our result, but a close inspection of the discussed examples reveals that therein the Hall conductivities of the composite fermions are integer quantized as opposed to the half-integer quantized values that enter our formula This fact is a consequence of the flux attachment to the physical electrons measured from the bottom of the lowest Landau level.

Quantum Many-Particle Systems - Boulder, Colorado: Westview Press. An Introduction to Quantum Field Theory - Additionally, one obtains a similar equation for the first variational derivative with respect to the classical components of the gauge fields Such equations, however, would be trivial, since their solutions for the quantum components of the gauge fields are constrained to vanish.
Note that the magnetic field in the Zeeman term is not affected by the statistical magnetic field. That means the Keldysh components can be parametrized by the respective retarded and advanced components as. We have to mention here that interactions may nevertheless lead to interesting observable consequences in the realm of the integer quantum Hall effect A possible scenario is a degeneracy breaking of certain, if not all noninteracting Landau levels of the multicomponent quantum Hall system The lifted degeneracy, in turn, would lead to the formation of additional plateaus in the Hall spectrum This kind of interaction effect clearly has to be distinguished from the fractional quantum Hall effect, as the underlying physical mechanisms for both phenomena vastly differ We do not consider interaction effects of this kind in the present paper, and refer to Refs and references therein for a more elaborate discussion see also Refs.
To be exact, the Fadeev-Popov determinant can be absorbed into the normalization constant only, if it does not depend on the gauge field itself This is not always the case, specifically in non-Abelian gauge theories, or if the gauge fixing function contains powers of the gauge field larger than or equal to two In that case, the Fadeev-Popov determinant leads to an additional contribution to the action known as Fadeev-Popov ghosts In the present paper, however, we are dealing with an Abelian gauge theory and consider linear gauge fixing functions only, such that the above mentioned problems are avoided.

Retrieved Effects of Landau level mixing on the fractional quantum Hall effect in monolayer graphene. First measurements in this magnetic field region on silicon field-effect transistors were not successful because the disorder in these devices was so large that all electrons in the lowest Landau level were localized.
