Detecting non-Abelian statistics with an electronic Mach-Zehnder interferometer.
Fractionally charged quasiparticles in the quantum Hall state with a filling factor nu=5/2 are expected to obey non-Abelian statistics. We demonstrate that their statistics can be probed by transport measurements in an electronic Mach-Zehnder interferometer. The tunneling current through the interferometer exhibits a characteristic dependence on the magnetic flux and a nonanalytic dependence on...
متن کاملNonequilibrium dephasing in an electronic Mach-Zehnder interferometer.
We study nonequilibrium dephasing in an electronic Mach-Zehnder interferometer. We demonstrate that the shot noise at the beam splitter of the interferometer generates an ensemble of nonequilibrium electron density configurations and that electron interactions induce configuration-specific phase shifts of an interfering electron. The resulting dephasing exhibits two characteristic features, a l...
متن کاملMach–Zehnder–Fano interferometer
We introduce a concept of the Mach–Zehnder–Fano interferometer by inserting a cavity exhibiting Fano resonance into a conventional interferometer. By employing the scattering-matrix approach, we demonstrate that the transmission becomes sensitive to a position of the cavity such that an asymmetric structure exhibits a series of narrow resonances with almost perfect reflection. We discuss how to...
متن کاملResonant dephasing in the electronic Mach-Zehnder interferometer.
We address the recently observed unexpected behavior of Aharonov-Bohm oscillations in the electronic Mach-Zehnder interferometer that was realized experimentally in a quantum Hall system [I. Neder, Phys. Rev. Lett. 96, 016804 (2006)10.1103/PhysRevLett.96.016804]. We argue that the measured lobe structure in the visibility of oscillations and the phase rigidity result from a strong long-range in...
متن کاملBell’s inequality for the Mach-Zehnder interferometer
If a single photon impinges on a Mach-Zehnder interferometer, the probability of detecting the photon in a certain output channel depends on the difference between the phase delays imposed by the two interfering channels. The photon behaves as if it goes through both interfering channels. On the other hand, if detectors are inserted into each interfering channel, the photon is only detected in ...
