What was discovered

Pines and Bohm proposed the plasmon as a quasiparticle quantizing the collective oscillations of the electron gas in a metal, analogous to the photon for light; it explains why metals reflect visible light yet become transparent at higher frequencies.

What it led to

  • Understanding of the optical properties of metals and semiconductors
  • Later birth of the field of plasmonics
  • Applications in molecular sensing, lithography and photovoltaics
