Reentrant Kondo effect in a quantum impurity coupled to a metal-semiconductor hybrid contact

G. Diniz, G. S. Diniz, G. B. Martins +1

Using NRG, we show that a system containing a quantum impurity (QI), strongly coupled to a semiconductor (gap $2\Delta$) and weakly coupled to a metal, displays a 'reentrant' Kondo sta…
