Non-equilibrium frequency-dependent noise through a quantum dot: A real time functional renormalization group approach
C. P. Moca, P. Simon, C. H. Chung +1
We construct a real time current-conserving functional renormalization group (RG) scheme on the Keldysh contour to study frequency-dependent transport and noise through a quantum d…

Quantum phase transition in a gapped Anderson model: A numerical renormalization group study
Catalin Pascu Moca, Adrian Roman
We use the numerical renormalization group method to investigate the spectral properties of a single-impurity Anderson model with a gap δ across the Fermi level in the conduction-e…
