Transport simulations in correlated one-dimensional systems — •Malcolm Einhellinger and Alex Cojuhovschi — Leibniz Universität Hannover, Germany
We develop a numerical approach for investigating transport properties in correlated low-dimensional solids and nanosystems. The time-evolving block decimation method is used to simulate the nonequilibrium dynamics in finite one-dimensional lattices. Stationary transport properties are then obtained by scaling the finite-system results. The method is illustrated with the conductance of correlated one-dimensional conductors (Luttinger liquids) such as the Hubbard model and the spinless fermion model. Comparisons with exact results confirm the validity of our approach.
