Kivonatos ismertetes:

Four decades ago Hanbury Brown and Twiss demonstrated that
intensity-intensity correlations can be used to measure the diameter of
stars. With their experiments they pioneered the investigation of the
fluctuation properties of light. In this talk I present the electrical analog
of the Hanbury Brown and Twiss effects. Of interest are current-current
correlations in multiprobe mesoscopic electrical conductors. I present a
theoretical discussion of current fluctuations and a comparison with recent
experiments in mesoscopic conductors. I discuss exchange effects, the role of
quasi-elastic and inelastic scattering and charge fluctuations which
determine the frequency-dependence of the noise spectra.
