Bose-Metals and non-Fermi-liquid metals.dvi
Underlying the quantum theory of many-particle non-relativistic systems are the canonical quantum fluids superfluid phases of Bosons and Fermiliquid phases of Fermions. These two quantum phases of matter are extremely well understood, and are both accessible from models of weakly interacting particles. The only low energy excitation in a superfluid is the Goldstone mode of the broken particle n...
متن کاملNon-Fermi-liquid behavior in d- and f-electron metals
A relatively new class of materials has been found in which the basic assumption of Landau Fermi-liquid theory—that at low energies the electrons in a metal should behave essentially as a collection of weakly interacting particles—is violated. These ‘‘non-Fermi-liquid’’ systems exhibit unusual temperature dependences in their low-temperature properties, including several examples in which the s...
متن کاملRKKY interaction and intrinsic frustration in non-Fermi-liquid metals.
We study the RKKY interaction in non-Fermi-liquid metals. We find that the RKKY interaction mediated by some non-Fermi-liquid metals can be of much longer range than for a Fermi liquid. The oscillatory nature of the RKKY interaction thus becomes more important in such non-Fermi liquids, and gives rise to enhanced frustration when the spins form a lattice. Frustration suppresses the magnetic ord...

متن کاملThe two-channel Kondo route to non-Fermi-liquid metals
We present a pedagogical and critical overview of the two-channel Kondo model and its possible relevance to a number of non-Fermi-liquid alloys and compounds. We survey the properties of the model, how a magnetic two-channel Kondo effect might obtain for Ce3+ ions in metals, and a quadrupolar Kondo effect for U4+ ions in metals. We suggest that the incoherent metal behaviour of the two-channel ...
