ORTVAY KOLLOKVIUM

2001. aprilis 26., csutortok, 15 orakor
Az ELTE Pazmany Peter s. 1/A alatti epuleteben
az 1. emeleti 1.69 eloadoban

(University of Geneva)
"Hanbury Brown Twiss effects in electrical conductors, shot noise in
mesoscopic conductors"


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.

Minden erdeklodot szivesen latunk! Az eloadas elott negyed oraval a 1.69 sz.
terem bejarata elott teat szolgalunk fel.
