We explore theoretically how nonlocal corrections in the description of themetal affect the strong coupling between excitons and plasmons in typicalexamples where nonlocal effects are anticipated to be strong, namely smallmetallic nanoparticles, thin metallic nanoshells or dimers with narrowseparations, either coated with or encapsulating an excitonic layer. Throughdetailed simulations based on the generalised nonlocal optical response theory,which simultaneously accounts both for modal shifts due to screening and forsurface-enhanced Landau damping, we show that, contrary to expectations, theinfluence of nonlocality is rather limited, as in most occasions the width ofthe Rabi splitting remains largely unaffected and the two hybrid modes are welldistinguishable. We discuss how this behaviour can be understood in view of thepopular coupled-harmonic-oscillator model, while we also provide analyticsolutions based on Mie theory to describe the hybrid modes in the case ofmatryoshka-like single nanoparticles. Our analysis provides an answer to a sofar open question, that of the influence of nonlocality on strong coupling, andis expected to facilitate the design and study of plexcitonic architectureswith ultrafine geometrical details.
