Noise removal at the rod synapse of mammalian retina
(Cambridge University Press, 1998)
Mammalian rods respond to single photons with a hyperpolarization of about 1 mV which is accompanied by continuous noise. Since the mammalian rod bipolar cell collects signals from 20-100 rods, the noise from the converging ...
Multiple scattering of classical waves: microscopy, mesoscopy, and diffusion
(The American Physical Society, 1999)
A tutorial discussion of the propagation of waves in random media is presented. To a first approximation the transport of the multiple scattered waves is given by diffusion theory, but important corrections are presented. ...
Optical conductance fluctuations: Diagrammatic analysis in the Landauer approach and nonuniversal effects
(The American Physical Society, 1995-06)
The optical conductance of a multiple scatering medium is defined as the total transmitted light of a normalized diffuse incoming beam. This quantity, analogous to electronic conductance, exhibits universal conductance ...
Density of states of disordered systems
(The American Physical Society, 1994-05-15)
Density of states calculations for the tight-binding model with diagonal disorder are presented. An instanton approach is used to calculate the tails of the spectrum, including all prefactors. It is shown that a Hartree ...
Third cumulant of the total transmission of diffuse waves
(The American Physical Society, 1995)
The probability distibution of the total transmission is studied for waves multiply scattered from a random, static configuration of scatterers. A theoretical study of the second and third cumulants of this distribution ...
Deviations from the Gaussian distribution of mesoscopic conductance fluctuations
(The American Physical Society, 1997)
The conductance distribution of metallic mesoscopic systems is considered. The variance of this distribution describes the universal conductance fluctuations, yielding a Gaussian distribution of the conductance. We calculate ...
