The nonlocal quantum response of metal has attracted a great deal of interest in the last year. In this letter Teperik et al. were able to carry out fully quantum calculations for plasmonic dimers with relatively large size. A interesting comparison with results from classical electromagnetic calculations based on local and nonlocal hydrodynamic response reveals the shortcomings of classical treatments.
