Our research is divided into two main topics: dynamics of charge and excitation energy transfer, and subsystem DFT method development. We pursue state-of-the-art theory development as well as applications related to materials design, plasmonics, electron transfer in biosystems and molecule-surface interactions.
Ground State and Time-dependent Orbital-Free Density Functional Theory
This project involves the development of novel nonlocal noninteracting kinetic energy functionals for bulk, semi-infinite and finite systems. Code development in DFTpy and eDFTpy (to be released).
Subsystem Time-Dependent Density Functional Theory
This project involves the development of a real-time TDDFT algorithm for treating molecules and materials interacting with metal and semiconducting surfaces. This project will take place in our own embedded Quantum-ESPRESSO and eDFTpy (to be released).
Non-Adiabatic Dynamics with Subsystem DFT
This project involves the development of electronic structure methods to carry out non-adiabatic molecular dynamics simulations in the framework of subsystem DFT. The code development for this project takes place in ADF and embedded Quantum-ESPRESSO suites of software.
The new methods will be applied to a range of problems:
- Photovoltaic systems
- Organic-Metal and Organic-Semiconductor interfaces
Non-Local Potentials for Subsystem DFT
Interactions between subsystems, covalent bonds as well as weak van der Waals, are challenging for subsystem DFT when semilocal nonadditive functionals are employed. This project involves the development of non-local orbital-free and orbital-dependent embedding potentials for the correct treatment of these interactions between subsystems.
