Chiroptical harmonic scattering (CHS) was predicted in 1979, but an experimental observation of this effect remained elusive for 40 years. A first form of CHS was reported in 2019; it was demonstrated that light scattered at the second-harmonic from Ag nanohelices dispersed in water could reveal the chirality of the nanohelices. Observations in other systems (metal and semiconductor) and at the thirdharmonic quickly followed. In this seminar, I will outline the progress so far (on arguing with referees), will report on the latest results and will present future challenges and opportunities.
