This review explains the relationship between density functional theory and strongly
correlated models using the simplest possible example, the two-site Hubbard model. The …

Density-functional theory (DFT) and model Hamiltonians are conceptually distinct
approaches to the many-particle problem, which can be developed and applied …

We have developed an efficient simulation tool'GOLLUM'for the computation of electrical,
spin and thermal transport characteristics of complex nanostructures. The new multi-scale …

Real-time Green's function simulations of molecular junctions (open quantum systems) are
typically performed by solving the Kadanoff-Baym equations (KBE). The KBE, however …

We present a numerical method for the study of correlated quantum impurity problems out of
equilibrium, which is particularly suited to address steady-state properties within dynamical …

We review one of the most versatile theoretical approaches to the study of time-dependent
correlated quantum transport in nano-systems: the non-equilibrium Green's function (NEGF) …

Quantum transport of strongly correlated fermions is of central interest in condensed matter
physics. While the stationary expansion dynamics have recently been measured with cold …

The Hubbard model is a prototype for strongly correlated many-particle systems, including
electrons in condensed matter and molecules, as well as for fermions or bosons in optical …

Quantum dynamics in strongly correlated systems are of high current interest in many fields
including dense plasmas, nuclear matter and condensed matter and ultracold atoms. An …
