PicoPhotonics: Extreme Nano-Optics with single molecules and monolayers

Speaker: Prof. Jeremy J. Baumberg (Cambridge University)

Venue: Queens Buildings N/3.28

I will discuss how we have discovered how to confine light to the scale of a single atom. This allows us to routinely watch individual molecules and bonds vibrating, as well as the movement of atoms under ambient conditions. Using DNA origami we now couple several dye molecules together optomechanically, and produce strong-light matter coupling that changes their quantum emission properties. We also watch redox chemistry in real time, watching single electrons shuttle in and out of single molecules, as well as 2D materials confined in the same gap. Prospective applications range from (bio)molecular sensing to fundamental quantum science, as well as nanomachines.
