Spectral properties of strongly correlated multi impurity models in the Kondo insulator regime: Emergent coherence, metallic surface states and quantum phase transitions
Fabian Eickhoff, Frithjof B. Anders
We investigate the real-space spectral properties of strongly-correlated multi-impurity arrays in the Kondo insulator regime. Employing a recently developed mapping onto an effecti…

Kondo holes in strongly correlated impurity arrays: RKKY driven Kondo screening and hole-hole interactions
Fabian Eickhoff, Frithjof B. Anders
The emerging and screening of local magnetic moments in solids has been investigated for more than 60 years. Local vacancies as in graphene or in Heavy Fermions can induce decouple…
