Ab initio study on heavy-fermion behavior in LiV${}_2$O${}_4$: Role of Hund's coupling and stability

Steffen Backes, Yusuke Nomura, Ryotaro Arita +1

LiV${}_2$O${}_4$ is a member of the so-called $3d$ heavy fermion compounds, with effective electron mass exceeding 60 times the free electron mass, comparable to $4f$ heavy fermion com…
