Theory for the coherence effects in the Kondo lattice
Abstract
The Kondo lattice model is studied by the functional integral method. Including Gaussian fluctuations it is possible to describe the cross-over from the coherent to the incoherent regime. The coherence temperature can be evaluated in this Gaussian approximation. It is then shown how this cross-over is reflected in the physical properties.
