Duality of f-electron in heavy fermion quantum criticality

Yun Kyu Bang

Chonnam National University

In this talk, I will review some of the selective experiments of heavy fermion compounds such as PuCoGa₅, CeM(Co, Rh, Ir)In₅ and others. I will focus on the non-Fermi liquid properties of these compounds, its relation to QCP, and the difference of the low energy scales between PuCoGa₅ and CeMIn₅. It will be argues that the duality of f-electrons is the key to understand these strongly correlated system in an unified way. I will introduce the theoretical method to capture the dual feature of f-electrons.
