, Harvard University
[Host: Paul Fendley]
I will present both the experimental results and the theory
for the non-equilibrium fluctuations of electric current in mesoscopic
systems (diffusive wires and chaotic quantum dots). Non-interacting
electrons exhibit Poissonian statistics while correlations in mesoscopic
systems lead to the universality of current fluctuations. I will
consider the effects of spin-polarized transport on the noise and
magnetoresistance of spintronic systems. Finally, the electron-optical
analogies will be discussed in relation to the fluctuations of radiation
from chaotic absorbing ('grey body') and amplifying ('random laser')
