Electronic transitions for a fully polarizable QM/MM approach based on fluctuating charges and fluctuating dipoles: Linear and corrected linear response regimes
Giovannini, Tommaso; Riso, Rosario Roberto; Ambrosetti, Matteo; Puglisi, Alessandra; Cappelli, Chiara (Journal article; Peer reviewed, 2019)The fully polarizable Quantum Mechanics/Molecular Mechanics (QM/MM) approach based on fluctuating charges and fluctuating dipoles, named QM/FQFμ [T. Giovannini et al., J. Chem. Theory Comput. 15, 2233 (2019)], is extended ... -
Engineering chemistry in the strong coupling regime: theoretical insights and new perspectives
Riso, Rosario Roberto (Doctoral theses at NTNU;2023:316, Doctoral thesis, 2023)Cavity quantum optics deals with the interaction of photons and molecules inside an optical cavity, i.e., in the region between two closely spaced mirrors. Perfect optical cavities can only support certain frequencies of ... -
Molecular orbital theory in cavity QED environments
Riso, Rosario Roberto; Haugland, Tor S.; Ronca, Enrico; Koch, Henrik (Peer reviewed; Journal article, 2022)Coupling between molecules and vacuum photon fields inside an optical cavity has proven to be an effective way to engineer molecular properties, in particular reactivity. To ease the rationalization of cavity induced effects ... -
On the characteristic features of ionization in QED environments
Riso, Rosario Roberto; Haugland, Tor S.; Ronca, Enrico; Koch, Henrik (Peer reviewed; Journal article, 2022)The ionization of molecular systems is important in many chemical processes, such as electron transfer and hot electron injection. Strong coupling between molecules and quantized fields (e.g., inside optical cavities) ... -
Strong Coupling in Chiral Cavities: Nonperturbative Framework for Enantiomer Discrimination
Riso, Rosario Roberto; Grazioli, Laura; Ronca, Enrico; Giovannini, Tommaso; Koch, Henrik (Peer reviewed; Journal article, 2023)The development of efficient techniques to distinguish mirror images of chiral molecules (enantiomers) is very important in both chemistry and physics. Enantiomers share most molecular properties except, for instance, the ... -
Surface-Enhanced Raman Spectroscopy for Environmental Monitoring
Lange, Christine Julia (Bachelor thesis, 2023)Prinsippene for overflateforbedret Raman-spektroskopi (SERS) blir utforsket med fokus på rollen den dielektriske responsen har i å modifisere det lokale elektriske feltet rundt en nanosfære. Drude-Lorentz-modellen brukes ...
