Chris Marianetti and his group's research focuses on computing materials behavior from the first-principles of quantum mechanics, including mechanical, electronic, and magnetic phenomena. Particular emphasis is placed on strongly correlated electron materials where density functional theory (DFT) computations tend to break down qualitatively. One of the Marianetti group's major research thrusts is developing a more advanced formalism which is based upon an integration of the dynamical mean-field theory (DMFT) and DFT. Other formal developments include first-principles-based approaches for studying extreme length and timescales which would traditionally be computationally formidable. Applications span the periodic table, from monolayers to transition metal oxides to actinides, with particular emphasis on materials related to energy storage and conversion.
