Multi-plasmon effects and plasmon satellites in photoemission from nanostructures
P. A. D. Gonçalves, F. Javier García de Abajo
Plasmons can be excited during photoemission and produce spectral photoelectron features that yield information on the nanoscale optical response of the probed materials. However,…
Gain-compensated cavities for the dynamic control of light-matter interactions
