Electron Interference in two Dimensions: Phase Measurements, Controlled Dephasing and Phase Recovery

Electron interference in the solid enables to determine the electron coherence time, the phase electron gains during transport, the statistics of quasi-particles in strongly interacting systems, and the processes of dephasing.

A few examples of electron interferometers constructed in two-dimensional electron gas will be provided and the following experiments will be described:

  •     the evolution of phase electrons accumulate as they traverse a coherent quantum dot,
  •     a simulation of an environment interacting with an interferometer by constructing a 'which path' detector, and
  •     the recovery of the phase in an already dephased system via experimentally 'looking' at only a part of the data ('post selection' measurements).
