Metallic phase in quantum Hall systems due to inter-Landau-band mixing.
The electronic eigenstates of a quantum Hall (QH) system are chiral states. Strong inter-Landau-band mixings among these states can occur when the bandwidth is comparable to the spacing of two adjacent Landau bands. We show that mixing of localized states with opposite chirality can delocalize electronic states. Based on numerical results, we propose the existence of a metallic phase between tw...
متن کاملPossible existence of a band of extended states induced by inter-Landau-band mixing in a quantum Hall system.
The mixing of states with opposite chiralities in a quantum Hall system is shown to have a delocalization effect. It is possible that extended states may form bands because of this mixing, as is shown through a numerical calculation on a two-channel network model. Based on this result, a new phase diagram with a narrow metallic phase separating two adjacent QH phases and/or separating a QH phas...

متن کاملLandau level substructure and mixing in the relativistic quantum Hall effect
We calculate the local density of states for a relativistic massless particle in the presence of crossed electric and magnetic fields. The Landau levels are broadened and aquire a modulation due to the electric field. We give detailed predictions for the shape of Landau levels in the relativistic case based on analytical expressions.
متن کاملComposite fermions and Landau-level mixing in the fractional quantum Hall effect.
The reduction of the energy gap due to Landau level mixing, characterized by the dimensionless parameter λ = (e/ǫl0)/h̄ωc, has been calculated by variational Monte Carlo for the fractional quantum Hall effect at filling fractions ν = 1/3 and 1/5 using a modified version of Jain’s composite fermion wave functions. These wave functions exploit the Landau level mixing already present in composite f...
