Electron transport through strongly correlated nano-structures: Frequency vs. real-time approach within DMRG — •Peter Schmitteckert — Institut für Theorie der Kondensierten Materie, Universität Karlsruhe, 76128 Karlsruhe, Germany

We provide an overview over various strategies to study the problem of electron transport through onedimensional, strongly correlated quantum systems within the framework of density matrix renormalization group calculations. Specifically we compare the Kubo formalism approach in frequency space, in which we calculate the linear dc conductance, with real time simulations, where we extract the conductance from the real-time evolution of suitably chosen initial states.
