Abstract
We calculate magnetic field fluctuations above a conductor with a nonlocal response
(spatial dispersion) and consider a large range of distances. The cross-over from
ballistic to diffusive charge transport leads to a reduced noise spectrum at distances
below the electronic mean free path, as compared to a local description. We also find that
the mean free path provides a lower limit to the correlation (coherence) length of the
near field fluctuations. The short-distance behaviour is…
