As its name suggests, the 1988 workshop on "Interacting Electrons
in Reduced Dimen the wide variety of physical effects that are
associated with (possibly sions" focused on strongly) correlated
electrons interacting in quasi-one- and quasi-two-dimensional mate
rials. Among the phenomena discussed were superconductivity,
magnetic ordering, the metal-insulator transition, localization,
the fractional Quantum Hall effect (QHE), Peierls and spin-Peierls
transitions, conductance fluctuations and sliding charge-density
(CDW) and spin-density (SDW) waves. That these effects appear most
pronounced in systems of reduced dimensionality was amply
demonstrated at the meeting. Indeed, when concrete illustrations
were presented, they typically involved chain-like materials such
as conjugated polymers, inorganic CDW systems and organie
conductors, or layered materials such as high-temperature
copper-oxide superconductors, certain of the organic
superconductors, and the QHE samples, or devices where the
electrons are confined to a restricted region of sample, e. g. ,
the depletion layer of a MOSFET. To enable this broad subject to be
covered in thirty-five lectures (and ab out half as many posters),
the workshop was deliberately focused on theoretical models for
these phenomena and on methods for describing as faithfully as
possible the "true" behav ior of these models. This latter emphasis
was especially important, since the inherently many-body nature of
problems involving interacting electrons renders conventional effec
tive single-particle/mean-field methods (e. g. , Hartree-Fock or
the local-density approxi mation in density-functional theory)
highly suspect. Again, this is particularly true in reduced
dimensions, where strong quantum fluctuations can invalidate
mean-field results.
