    What Quantity is Measured in an Excess Noise Experiment?

    Consider a measurement in which the current coming out of a mesoscopic sample is filtered around a frequency Ω > 0, then amplified, measured, squared, then this process is repeated many times and the results a...

    The Fano Effect in Aharonov-Bohm Interferometers

    After briefly reviewing the Fano effect, we explain why it may be relevant to various types of Aharonov–Bohm interferometers. We discuss both closed (electron conserving) and open interferometers, in which one...

    On the Detection of Quantum Noise and Low-Temperature Dephasing

    We discuss the detection of quantum fluctuations in the light of the general van Hove - type relationship between time-dependent correlators and measurable properties. Considering the interaction between the f...

    Dephasing and Shot-Noise in Mesoscopic Systems

    The general principles of dephasing of quantum-mechanical interference by coupling to the environment degrees of freedom are summarized. A general expression for the dephasing rate is obtained and used to rede...

    Exchange interaction effects in inter-Landau level Auger scattering in a two-dimensional electron gas

    We consider the influence of spin effects on the inter-Landau level electron-electron scattering rate in a two-dimensional electron gas. Because of exchange spin splitting, the Landau levels are not equidistan...

    Coherent Optical Phenomena of Quantum Well Excitons in a Magnetic Field

    We present results of differential absorption and four wave mixing experiments in GaAs quantum wells in a magnetic field. Quantum beats between the exciton Zeeman levels and a rotation of the photon echo polar...
