Interacting lattice electrons with disorder in two dimensions: Numerical evidence for a metal-insulator transition with a universal critical conductivity
Prabuddha B. Chakraborty, Krzysztof Byczuk, Dieter Vollhardt
The dc-conductivity of electrons on a square lattice interacting with a local repulsion in the presence of disorder is computed by means of quantum Monte Carlo simulations. We prov…
Electronic correlations at the alpha-gamma structural phase transition in paramagnetic iron
I. Leonov, A. I. Poteryaev, V. I. Anisimov +1
We compute the equilibrium crystal structure and phase stability of iron at the alpha(bcc)-gamma(fcc) phase transition as a function of temperature, by employing a combination of a…
Route to ferromagnetism in organic polymers
Zsolt Gulacsi, Arno Kampf, Dieter Vollhardt
Employing a rigorous theoretical method for the construction of exact many-electron ground states we prove that interactions can be employed to tune a bare dispersive band structur…
Dynamical Mean-Field Theory of Electronic Correlations in Models and Materials
Dieter Vollhardt
The concept of electronic correlations plays an important role in modern condensed matter physics. It refers to interaction effects which cannot be explained within a static mean-f…
Distribution of the local density of states as a criterion for Anderson localization: Numerically exact results for various lattices in two and three dimensions
Gerald Schubert, Jens Schleede, Krzysztof Byczuk +2
Numerical approaches to Anderson localization face the problem of having to treat large localization lengths while being restricted to finite system sizes. We show that by finite-s…
