Lanczos transformation for quantum impurity problems in d-dimensional lattices: application to graphene nanoribbons
C. A. Busser, G. B. Martins, A. E. Feiguin
We present a completely unbiased and controlled numerical method to solve quantum impurity problems in d-dimensional lattices. This approach is based on a canonical transformation,…

Kondo regime in triangular arrangements of quantum dots: Molecular orbitals, interference and contact effects
E. Vernek, C. A. Busser, G. B. Martins +3
Transport properties of an interacting triple quantum dot system coupled to three leads in a triangular geometry has been studied in the Kondo regime. Applying mean-field finite-U…
