Whenever standard density functional theory fails because of strong correlations, the dynamical mean-field theory comes into play. This theory, developed in the early nineties, is one of the most successful approaches for describing strongly-correlated systems and Mott transitions.
We work on up-to-date implementations of the DFT+DMFT framework, constantly implementing new features into our code packages that are released as the TRIQS/DFTTools application. At the moment there is an interface to the Wien2k band structure code, and several DMFT solvers and post-processing tools.
Topological states of matter received increasing attention in recent years due to their fascinating properties. Strong spin-orbit coupling is a key element for this effect to show up in real materials. In this project, we are interested in the mutual influence of spin-orbit coupling and strong electron correlations, and possible realisations of topological phases in strongly-correlated materials.
This project is funded by the FWF through the START program.
