The Metal–insulator Transition in One Dimension
The low–energy excited states of a system of interacting one–dimensional fermions in a conducting state are collective charge and spin density oscillations. The unusual physical properties of such a system (called “Luttinger liquid”) are characterized by the velocities uρ and uσ of the charge and spin excitations, as well as by a parameter Kρ that determines the power law behavior of correlatio...
متن کاملInsulator/Chern-insulator transition in the Haldane model
We study the behavior of several physical properties of the Haldane model as the system undergoes its transition from the normal-insulator to the Chern-insulator phase. We find that the density matrix has exponential decay in both insulating phases, while having a power-law decay, more characteristic of a metallic system, precisely at the phase boundary. The total spread of the maximally locali...

متن کاملHausdorff dimension, anyonic distribution functions and duality
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 h̃ = 3 − h. In this way, we confirm that the filling factors fo...
