title: Plasmonic nanoclocks.
abstract: Plasmonic spectra of "nanoclock" metamaterials can be topologically mapped on a torus. We manufactured arrays of such a metamaterial with different "time" shown on the clocks and demonstrated that the near-infrared spectra of the nanostructures can be predictably tuned exhibiting a rich series of high-order plasmon modes, from the electric dipole to exotic electric triakontadipole that could be engaged in chemo/biosensor applications.
