Looking forward, we anticipate that the HADOKEN software package could be used in a variety of other applications that require electronic structure calculations of these unique structures. For example, since our calculations demonstrate that electron gases at nanoscale core-shell interfaces differ significantly from their bulk counterparts, we anticipate that other observables such as electron transport or optical properties in these systems would also exhibit unique behavior. As such, the wavefunctions and total electron densities computed by the HADOKEN code can serve as a starting point to initialize the computation of these dynamical properties. Similarly, the self-consistent algorithms in the HADOKEN code can also be further parallelized or modified to include other many-body effects (such as nonlocal exchange-correlation effects ) that may have a significant influence on electron localization effects observed in these systems. The open-source HADOKEN software code enables a path forward to explore these other properties as well as provides an easy-to-use, predictive tool to understand and modulate electron confinement effects in these unique nanosystems.
