Research Overview

I currently work on combining the complex-scaling method with density functional theory (DFT). The complex-scaling method is a technique for calculating resonance states. Standard DFT is incapable of describing such states as they are not the ground state. The combination will, due to the high efficiency of DFT, allow for the calculation of resonance states in realistic systems and at larger scale than what is otherwise possible.
