Physics of Molecular Organic Conductors
The richness of the physics of electrons in solids continues to
grow. Besides correlated and quantum phenomena like magnetism and
superconductivity (no longer the arch enemies they were long thought to be)
and spin and charge density waves, even semiclassical electron motion in
magnetic fields brings new surprises. Experiments and simulations on
so-called quasi-one dimensional systems help us discover and explain the
many faces and facets of the electron when its motion is confined. These
are perhaps best manifest in the molecular organic conductors, such as
TMTSF, where several novel angular magnetoresistance oscillation (AMRO)
effects have been observed in the metal phase, while the superconducting
state appears to be spin triplet, a rare if not unique occurrence in nature.
