Mach Zehnder Interferometer

We study properties of the simplest type of electron interferometer, the Mach-Zehnder Interferometer (MZI) in the Integer Quantum Hall (IQH) regime. In this work, in order to analyse the novel experimental results reported by I. Neder et al. [Phys. Rev. Lett.96, 016804 (2006)] which makes questionable the validity of Landauer-Buttiker formalism in the IQH regime, we have derived expressions for tunneling currents through the electronic MZI system whithin the model of quantum dissipation induced by an environment. In this model the MZI system is coupled to a dissipative environment, where the dissipation is introduced by coupling the MZI system to a frequency-independent Ohmic impedance Z(ω) = R.

Circulating Currents

A novel photocurrent effect induced by Terahertz (THz) radiation in two-dimensional (2D) electron systems is reported. It was found that when the system is tuned to electron cyclotron resonance conditions, THz radiation induces a visible signal related to currents flowing in the plane of 2D electron systems without any external bias. This effect is employed as a technique for the study of the integer Quantum Hall samples in the absence of external bias. Our data indicate that at the integer ν the photocurrents are circulating currents in the dissipationless quantum Hall regime.
