 abstract = {A many-body theory of paramagnetic Kondo insulators is described,
focusing specifically on single-particle dynamics, scattering rates, dc
transport and optical conductivities. This is achieved by development of
a non-perturbative local moment approach to the symmetric periodic
Anderson model within the framework of dynamical mean-field theory. Our
natural focus is the strong-coupling, Kondo lattice regime, in
particular the resultant `universal' scaling behaviour in terms of the
single, exponentially small low-energy scale characteristic of the
problem. Dynamics/transport on all relevant (omega, T)-scales are
considered, from the gapped/activated behaviour characteristic of the
low-temperature insulator through to explicit connection to
single-impurity physics at high omega and/or T; and for optical
conductivities emphasis is given to the nature of the optical gap, the
temperature scale responsible for its destruction and the consequent
clear distinction between indirect and direct gap scales. Using scaling,
explicit comparison is also made to experimental results for dc
transport and optical conductivities of Ce(3)Bi(4)Pt(3), SmB(6) and
YbB(12). Good agreement is found, even quantitatively; and a mutually
consistent picture of transport and optics results.},
