Аннотация: The influence of quantum effects, such as spatial nonlocality and splitting of electron cloud near the surface,on the extinction cross-section and field intensity in the gap between particles was analyzed via the Discrete Source Method using a pair of plasmonic gold nanoparticles. In this case, spatial nonlocality is described within the framework of the Generalized Nonlocal Optical Response Theory, while the splitting of the electron cloud is accounted for by using the theory of mesoscopic boundary conditions with Feibelman parameters. It has been found that mesoscopic boundary conditions lead to restoring of the plasmon resonance amplitude compared to thevolume nonlocal effect.https://journals.ioffe.ru/articles/57294
