Dipolar coupling of nanoparticle-molecule assemblies: An efficient approach for studying strong coupling
Jakub Fojt, Tuomas P. Rossi, Tomasz J. Antosiewicz +2
Strong light-matter interactions facilitate not only emerging applications in quantum and non-linear optics but also modifications of materials properties. In particular the latter…
Real-Time Time-Dependent Density Functional Theory Implementation of Electronic Circular Dichroism Applied to Nanoscale Metal-Organic Clusters
Esko Makkonen, Tuomas P. Rossi, Ask Hjorth Larsen +4
Electronic circular dichroism (ECD) is a powerful spectroscopical method for investigating chiral properties at the molecular level. ECD calculations with the commonly used linear-…
Hot-Carrier Generation in Plasmonic Nanoparticles: The Importance of Atomic Structure
Tuomas P. Rossi, Paul Erhart, Mikael Kuisma
Metal nanoparticles are attractive for plasmon-enhanced generation of hot carriers, which may be harnessed in photochemical reactions. In this work, we analyze the coherent femtose…
Strong plasmon-molecule coupling at the nanoscale revealed by first-principles modeling
Tuomas P. Rossi, Timur Shegai, Paul Erhart +1
Strong light-matter interactions in both the single-emitter and collective strong coupling regimes attract significant attention due to emerging quantum and nonlinear optics applic…
Plasmon excitations in mixed metallic nanoarrays
Kevin Conley, Neha Nayyar, Tuomas P. Rossi +4
We study the plasmonic properties of arrays of atomic chains which comprise noble (Cu, Ag, and Au) and transition (Pd, Pt) metal atoms using time-dependent density-functional theor…
Localized surface plasmon resonance in silver nanoparticles: Atomistic first-principles time-dependent density-functional theory calculations
Mikael Kuisma, Arto Sakko, Tuomas P. Rossi +4
We observe using ab initio methods that localized surface plasmon resonances in icosahedral silver nanoparticles enter the asymptotic region already between diameters of 1 and 2 nm…
