Plasmon spectra of nanospheres under a tightly focused beam
Nassiredin M. Mojarad, Vahid Sandoghdar, Mario Agio
We study the modification of the far-field cross sections and the near-field enhancement for gold and silver nanospheres illuminated by a tightly focused beam. Using a multipole-ex…

Coupling of plasmonic nanoparticles to their environments in the context of van der Waals-Casimir interactions
U. Håkanson, M. Agio, S. Kühn +3
We present experiments in which the interaction of a single gold nanoparticle with glass substrates or with another gold particle can be tuned by in-situ control of their separatio…

Scanning Near-Field Optical Coherent Spectroscopy of Single Molecules at 1.4 Kelvin
I. Gerhardt, G. Wrigge, M. Agio +3
We present scanning near-field extinction spectra of single molecules embedded in a solid matrix. By varying the molecule-tip separation, we modify the line shape of the spectra, d…
