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.
