Quantum impurity models describe an atom or molecule embedded in a host material with
which it can exchange electrons. They are basic to nanoscience as representations of …

Strong electronic correlations pose one of the biggest challenges to solid state theory.
Recently developed methods that address this problem by starting with the local, eminently …

The study of nonequilibrium phenomena in correlated lattice systems has developed into
one of the most active and exciting branches of condensed matter physics. This research …

Strong electronic correlations are often associated with the proximity of a Mott-insulating
state. In recent years however, it has become increasingly clear that the Hund's rule …

In the last two decades non-equilibrium spectroscopies have evolved from avant-garde
studies to crucial tools for expanding our understanding of the physics of strongly correlated …

Superconductivity with a remarkably high T c has recently been found in Sr-doped NdNiO 2
thin films. While this system bears strong similarities to the cuprates, some differences, such …

Two-dimensional materials, obtained by van der Waals stacking of layers, are fascinating
objects of contemporary condensed matter research, exhibiting a variety of new physics …

Featuring detailed explanations of the major algorithms used in quantum Monte Carlo
simulations, this is the first textbook of its kind to provide a pedagogical overview of the field …

We compute the electronic structure, momentum resolved spectral function and optical
conductivity of the new superconductor LaO 1-x F x FeAs within the combination of the …

We show that in multiband metals the correlations are strongly affected by Hund's rule
coupling, which depending on the filling promotes metallic, insulating or bad-metallic …
