SUMMARY:Electronic transport in inhomogeneous quantum wires\, R. G. He
 rb Condensed Matter Seminar\, Jerome Rech\, Argonne National Laborator
 y
DESCRIPTION:Perhaps more importantly than the observation of character
 istic signatures of one-dimensional physics\, the reports of anomalies
  in the transport properties of quantum wires focused a lot of attenti
 on on these systems. From the theoretical point of view\, these result
 s initiated various attempts to study the effects of electron-electron
  interactions on the transport properties of one-dimensional conductor
 s. In this talk\, I will explain how non-uniform interactions along th
 e wire may lead to substantial contributions to the transport properti
 es. I will show that these inhomogeneities of the system lead to a fin
 ite resistivity associated with electron-electron scattering processes
  which weakly violate the momentum conservation. Using an alternative 
 approach compatible with the bosonization formalism\, I will compare t
 hese results to previous works relying on an extension of the Tomonaga
 -Luttinger model to inhomogeneous systems.
