Excited States from Restricted Open Shell Plane-Wave DFT
Michael J. Sahre, Marco Romanelli, Martijn Marsman +2
Variational excited-state density functional theory (DFT) enables the calculation of excited states at a cost comparable to ground-state calculations, but single-configuration appr…

Quantized plasmon modes for metallic nanoparticles of arbitrary shape with a generic dielectric function
Marco Romanelli, Gabriel Gil, Stefano Corni
In this work we introduce an effective approach to quantize the electromagnetic response of plasmonic metallic nanostructures. Their shape is arbitrary and they feature a realistic…

Identifying differences between semi-classical and full-quantum descriptions of plexcitons
Marco Romanelli, Stefano Corni
Strong light-matter coupling between molecules and plasmonic nanoparticles give rise to new hybrid eigenstates of the coupled system, commonly referred to as polaritons, or more pr…
