HOW THE KONDO EFFECT CAN EXIST IN Gd INTERMETALLIC COMPOUNDS
Based on the crystal and magnetic structural properties of some Gd intermetallic compounds, it is shown that with increasing conduction electron concentration, Gd experiences electronic and magnetic instability, and that these behaviors point to the appearance of Kondo Lattice. We suggest that the conduction electrons have gained local character. It is shown that Kondo effect should be observed...

متن کاملQuasispecies can exist under neutral drift at finite population sizes
We investigate the evolutionary dynamics of a finite population of RNA sequences adapting to a neutral fitness landscape. Despite the lack of differential fitness between viable sequences, we observe typical properties of adaptive evolution, such as increase of mean fitness over time and punctuated equilibrium transitions. We discuss the implications of these results for understanding evolution...
