 abstract = {The symmetric periodic Anderson model is well known to capture the
essential physics of Kondo insulator materials. Within the framework of
dynamical mean-field theory, we develop a local moment approach to its
single-particle dynamics in the paramagnetic phase. The approach is
intrinsically non-perturbative, encompasses all energy scales and
interaction strengths, and satisfies the low-energy dictates of Fermi
liquid theory. It captures in particular the strong coupling behaviour
and exponentially small quasiparticle scales characteristic of the Kondo
lattice regime, as well as simple perturbative behaviour in weak
coupling. Particular emphasis is naturally given to strong coupling
dynamics, where the resultant clean separation of energy scales enables
the scaling behaviour of single-particle spectra to be obtained.},
