| dc.description | We propose that in highly anisotropic, strongly correlated materials a novel breakdown of Fermi-liquid theory can result: the motion of the electrons in one or more directions may become entirely incoherent due to interaction effects even in the limit of zero temperature and an arbitrarily pure system. This paper presents an introduction to our arguments as to why quantum coherence is relevant to hopping between liquids of strongly interacting electrons and how it should be lost for sufficiently strong interactions, even though the hopping may remain relevant in a renormalization group sense. In this case a state with confined coherence obtains, even though the electrons themselves are not confined to individual planes in the low-energy limit. This proposal offers a natural resolution of certain apparent contradictions in the experimentally determined properties of the high-temperature superconductors and can uniquely explain the striking magnetoresistance anomalies observed for the organic superconductor . |
