Abstract

This talk will focus on three absorbing lines of research into nanophotonics. It will begin with the first experimental observation of a chiroptical effect that was predicted 40 years ago.[1,2] Our team recently demonstrated that in chiral metal nanoparticles (those that lack mirror symmetry) the intensity of light, scattered at the secondharmonic frequency, is proportional to the chirality. This effect was predicted 40 years ago, it is >10,000 more sensitive than corresponding linear optical effects and it could enable safer pharmaceuticals. Next, it will consider the smallest backjets (‘nanojets’) ever created and will discuss how they can serve to assemble novel metamaterials based on nano metalworking.[3,4] Nano metalworking is an exciting, emerging field that is largely unexplored. Finally, it will illustrate how a vapour stabilization technique can greatly enhance quantum sensors.[5] REFERENCES [1] Phys Rev. X 9, 011024 (2019). [2] J. Chem. Phys. 70, 1027 (1979). [3] Adv.
