Authors: Alushi, Uesli; Ramos, Tomas; Garcia-Ripoll, Juan Jose; Di Candia, Roberto; Felicetti, Simone Journal: PRX QUANTUM Publication date: 2023/08/25 DOI: 10.1103/PRXQuantum.4.030326 Abstract: Quadratic light-matter interactions are nonlinear couplings such that quantum emitters interact with photonic or phononic modes exclusively via the exchange of excitation pairs. Implementable with atomic and solid-state systems, these couplings lead to [...]

Authors: Mitrushchenkov, Akexander O. O.; de Lara-Castells, Maria Pilar Journal: CHEMPHYSCHEM Publication date: 2023/08/15 DOI: 10.1002/cphc.202300317 Abstract: Novel highly selective synthesis techniques have enable the production of atomically precise monodisperse metal clusters (AMCs) of subnanometer size. These AMCs exhibit 'molecule-like' structures that have distinct physical and chemical properties, significantly different from those of nanoparticles and [...]
