Role of quantum coherence in series resistors.
TLDR
This work investigates the resistance of a series of two (or more) ob- stacles and study the transition from completely coherent transmission through the sample to completely incoherent transmission.Abstract:
Landauer's approach which yields the resistance of an obstacle in an otherwise perfect wire due to elastic scattering at the obstacle is augmented by including localized inelastic scatterers within the sample. The inelastic scatterers invoked consist of an electron reservoir coupled via a lead to the wire. The key advantage of this method is that the effect of inelastic scattering can be studied by solving an elastic scattering problem. We investigate the resistance of a series of two (or more) ob- stacles and study the transition from completely coherent transmission through the sample to completely incoherent transmission. For a sample with a small transmission probability, increasing inelastic scattering decreases the resistance. At an intermediate value of inelastic scattering, the resistance reaches a minimum to increase again when inelastic scattering processes start to dominate the resistance.read more

Shot noise in mesoscopic conductors
TL;DR: Theoretical and experimental work concerned with dynamic fluctuations has developed into a very active and fascinating subfield of mesoscopic physics as discussed by the authors, which can be used to obtain information on a system which is not available through conductance measurements.

Fabry - Perot interference in a nanotube electron waveguide
TL;DR: This work describes an example of a coherent molecular electronic device whose behaviour is explicitly dependent on quantum interference between propagating electron waves—a Fabry–Perot electron resonator based on individual single-walled carbon nanotubes with near-perfect ohmic contacts to electrodes.
