Abstract

Heavy fermions

Non-Fermi liquids

Quantum impurity problems

We exploit our recent boundary conformal field theory description (Johannesson et al., Phys. Rev. B 68 (2003) 075112) of the two-channel Anderson impurity model to construct its exact space- and time-dependent single-electron Green's function. The universal zero-temperature resistivity and leading temperature-dependent term are derived. We discuss possible implications for a quadrupolar-magnetic mixed-valent scenario for the UBe 13 compound.
