Global phase diagram of a spin-orbital Kondo impurity model and the suppression of Fermi-liquid scale
Y. Wang, E. Walter, S. -S. B. Lee +4
Many correlated metallic materials are described by Landau Fermi-liquid theory at low energies, but for Hund metals the Fermi-liquid coherence scale is found to be…

Uncovering Non-Fermi-Liquid Behavior in Hund Metals: Conformal Field Theory Analysis of an SU(2)SU(3) Spin-Orbital Kondo Model
E. Walter, K. M. Stadler, S. -S. B. Lee +4
Hund metals have attracted attention in recent years due to their unconventional superconductivity, which supposedly originates from non-Fermi-liquid (NFL) properties of the normal…

Breakdown of the Law of Reflection at a Disordered Graphene Edge
E. Walter, T. Ö. Rosdahl, A. R. Akhmerov +1
The law of reflection states that smooth surfaces reflect waves specularly, thereby acting as a mirror. This law is insensitive to disorder as long as its length scale is smaller t…
