Simultaneous ferromagnetic metal-semiconductor transition in electron-doped EuO
Michael Arnold, Johann Kroha
We present a general framework to describe the simultaneous para-to-ferromagnetic and semiconductor-to-metal transition in electron-doped EuO. The theory correctly describes detail…

Stable two-channel Kondo fixed point of an SU(3) quantum defect in a metal: renormalization group analysis and conductance spikes
Michael Arnold, Tobias Langenbruch, Johann Kroha
We propose a physical realization of the two-channel Kondo (2CK) effect, where a dynamical defect in a metal has a unique ground state and twofold degenerate excited states. In a w…
