Size effects in the electronic properties of finite arrays of exchange coupled quantum dots: A renormalization group approach

Jiaxiang Wang, Sabre Kais, F. Remacle +1

Transport properties of arrays of metallic quantum dots are governed by the distance-dependent exchange coupling between the dots. It is shown that the effective value of the excha…
