# On the limits of application of Anderson and Kondo models in physics of strongly correlated electron systems

@article{Sluchanko2015OnTL, title={On the limits of application of Anderson and Kondo models in physics of strongly correlated electron systems}, author={Nikolay Sluchanko}, journal={Low Temperature Physics}, year={2015}, volume={41}, pages={544-546} }

We argue that the Anderson and Kondo models turn out to be irrelevant for the description of some strongly correlated electron systems and suggest the mechanism for the formation of many-body states (heavy fermions) being an alternative to the Kondo one. This mechanism involves the quantum tunneling of a heavy particle between the states in the double-well potential.
