2 Research We are a research group on theoretical condensed matter physics. Our research covers a broad range of materials systems, bulk materials (metals, semiconductors, insulators), and alloys. Phenomena of interest include electronic properties, magnetic properties, pressure and dynamics. Our primary goal is to understand and predict materials properties at the most fundamental level using atomistic first principles ( ab initio ) quantum-mechanical calculations. quantum-mechanical calculations. For more details, please see our list of publications. For more details, please see our list of publications.

3 Research Topics Electronic Structure of Specific Bulk Solids Electronic Structure of Specific Bulk Solids Binary semiconductors and insulators. Metals. Magnetic semiconductors. Predicting new materials. Electronic structure of alloys Semiconductor alloys: Structural, Electronic and thermodynamic properties. Diluted Magnetic Semiconductor alloys. Pressure and Dynamical properties Pressure and Dynamical properties High pressure and dynamical properties of solids.
