Main Results:

  • Nonlinear effects at the single plasmon level are theoretically predicted in the visible range.
  • Two-plasmon interaction energy is comparable to plasmon linewidths.
  • Sub-Poissonian second-order correlation indicates nonclassical plasmon behavior.

Conclusions:

  • Weakly interacting nonlinear materials with plasmonic modes can exhibit single-plasmon nonlinearities.
  • Experimental detection is feasible using gold nanodimers and nonlinear materials.
  • Proposed configurations overcome limitations of short plasmonic lifetimes.
