Origin of non-Fermi liquid behavior in heavy fermion systems: A conceptual view
Abstract
We critically examine the non-Fermi liquid (NFL) behavior observed in heavy fermion systems located close to a magnetic instability and suggest a conceptual advance in physics in order to explain its origin. We argue that the treatment of electronic states responsible for magnetism near the Quantum Critical Point (QCP), should not be accomplished within the quantum mechanical formalism; instead they should be treated semi-classically. The observed NFL behavior can be explained within such a scenario. As a sequel we attempt to discuss its consequences for the explanation of high-TC superconductivity observed in Cuprates.

Total 16 pages incl. suppl. info. (at the end). This replacement elaborates the text of the supplementary information for our previous version (arXiv:1409.7156 v4) and refines the language of the presentation. Many of our ideas should become very clear after reading this version
