Fractional charges on an integer quantum Hall edge.
We propose ways to create and detect fractionally charged excitations in integer quantum Hall edge states. The charge fractionalization occurs due to the Coulomb interaction between electrons propagating on different edge channels. The fractional charge of the solitonlike collective excitations can be observed in time-resolved or frequency-dependent shot noise measurements.
متن کاملFractionalization noise in edge channels of integer quantum Hall states.
A theoretical calculation is presented of current noise which is due charge fractionalization, in two interacting edge channels in the integer quantum Hall state at filling factor ν=2. Because of the capacitive coupling between the channels, a tunneling event, in which an electron is transferred from a biased source lead to one of the two channels, generates propagating plasma mode excitations ...
متن کاملRelaxation and edge reconstruction in integer quantum Hall systems
The interplay between the confinement potential and the electron–electron interactions causes reconstructions of quantum Hall edges. We study the consequences of this edge reconstruction for the relaxation of hot electrons injected into integer quantum Hall edge states. In translationally invariant edges, the relaxation of hot electrons is governed by three-body collisions, which are sensitive ...
متن کاملNon-linear Transport in Quantum-Hall Smectics
Recent transport experiments have established that two-dimensional electron systems with high-index partial Landau level filling, ν∗ = ν − [ν], have ground states with broken orientational symmetry. In a mean-field theory, the broken symmetry state consists of electron stripes with local filling factor [ν] + 1, separated by hole stripes with filling factor [ν]. We have recently developed a theo...
متن کاملW1+∞ Dynamics of Edge Excitations in the Quantum Hall Effect
Quantum Hall universality classes can be classified by W1+∞ symmetry. We show that this symmetry also governs the dynamics of quantum edge excitations. The Hamiltonian of interacting electrons in the fully-filled first Landau level is expressed in terms of W1+∞ generators. The spectra for both the Coulomb and generic short-range interactions are thus found algebraically. We prove the one-dimens...
