Strong light-matter interactions in hybrid polaritonic systems
Ben Johns, Andrea Schirato, Federico Toffoletti +13
Strong light-matter coupling gives rise to polaritons - hybrid excitations whose mixed photonic and matter character enables control over optical, electronic and chemical propertie…
DMRG/FQ: a Polarizable Embedding Approach Combining Density Matrix Renormalization Group and Fluctuating Charges
Matteo Rinaldi, Chiara Sepali, Alicia Marie Kirk +2
We present an integrated multiscale framework that combines the Density Matrix Renormalization Group (DMRG) with a polarizable fluctuating-charge (FQ) force field for the simulatio…
plasmonX: an Open-Source Code for Nanoplasmonics
Tommaso Giovannini, Pablo Grobas Illobre, Piero Lafiosca +4
We present the first public release of plasmonX, a novel open-source code for simulating the plasmonic response of complex nanostructures. The code supports both fully atomistic an…
Analytical Nuclear Gradients for the Multiconfigurational Self-Consistent Field Method Coupled with the Polarizable Fluctuating Charges Model
Francesco Mazza, Marco Trinari, Chiara Sepali +1
The multiscale model combining the multiconfigurational self-consistent field (MCSCF) method with the fully atomistic polarizable Fluctuating Charges (FQ) force field (J. Chem. The…
Atomistic QM/Classical Modeling of Surface-Enhanced Infrared Absorption
Sveva Sodomaco, Piero Lafiosca, Tommaso Giovannini +1
We present a multiscale quantum mechanics/classical (QM/MM) approach for modeling surface-enhanced infrared absorption (SEIRA) spectra of molecules adsorbed on plasmonic nanostruct…
Vertical Excitation Energies of Embedded Systems: The Vertical Excitation Model (VEM) within Polarizable QM/MM
Chiara Sepali, Piero Lafiosca, Linda Goletto +2
Polarizable Quantum Mechanics/Molecular Mechanics (QM/MM) approaches based on fluctuating charges and dipoles (QM/FQ(F)) are formulated within the state-specific Vertical Excit…
