motion. However in many compounds, most notably heavy fermion materials and underdoped cuprates, this picture breaks down and the carriers can no longer be described as long-lived excitations as they acquire a finite lifetime. This behavior directly influences the transport properties leading to anomalies in the temperature dependence of the resistivity.

In this paper we present a general mechanism based on Mott physics and multi-band effects which leads to a metallic state with an extremely small FL coherence temperature. Empirically, this system will display a NFL behavior already at exceedingly small temperatures. The key element is the hybridization between a strongly correlated band and a weakly interacting band that leads to the formation of hybrid entities. The binding with the localized $f$-electrons hinders the motion of the carriers leading to a coherence temperature which is much smaller than the (already renormalized) scale predicted by FL theory on the basis of mass renormalization.

Our approach is based on the periodic Anderson model (PAM), a widely accepted correlated electrons model for the description of the heavy fermion physics. In its minimal form the PAM describes a set of non-dispersive strongly correlated electrons, hybridizing with a band of conduction electrons. In a general
