Earlier we proposed a modified version of the Anderson lattice model where the in-tersite coherence effects can be properly included even in the large limit of the spin-orbital degeneracy N and investigated the low temperature Fermi liquid properties rigorously in the limit N→ ∞. In the present study, using the same model as above, we investigate properties over the whole temperature range through explicit numerical calculations for 7V=6. We find that a coherence temperature T0 of order of one tenth of the Kondo temperature TK exists
at lower temperature T≲T0 the system is in the Fermi liquid state, while at higher temperature T≫ T0 the electrons are scattered incoherently by the Kondo impurities. At intermediate temperature, with increasing T, the hybridization gap appeared in the Fermi liquid state decreases rapidly at T≳ T0, then smoothly turns into the pseudo gap at T⋍ TK, and finally the dense Kondo regime is realized at T.
