Dynamic Behavior of Strongly Coupled Quantum Dots

ORAL

Abstract

We study a system of strongly correlated quantum dots, using a recently developed diagrammatic quantum Monte Carlo approach. Here, one calculates high orders of Schwinger-Keldysh perturbation theory and uses numerical resummation to obtain spectral functions directly in real time. We show that even non-Fermi liquid behavior of strongly coupled quantum dots can be revealed. We study this behavior in both equilibrium and in situations where the dots are driven by an external current.
