[phas-grad] [phas-dept] Sep 30 colloquium by a YouTube presentation (no meeting)

[Heungman Park]

Dear all in Physics and Astronomy,

We do not meet this week Thursday. Instead, we have a YouTube presentation below.

PHYS-401/501 students must complete an assignment (submitting a summary report) on D2L when there is no in-person meeting on a week.

MIT.nano Seminar Series:

On single photons and single molecules: From nano-quantum optics to nanobiophotonics

Prof. Vahid Sandoghdar

Jan 5, 2021



Vahid Sandoghdar, Alexander von Humboldt Professor in the Department of Physics at Friedrich Alexander University and the Director of the Max Planck Institute for the Science of Light, gave the December MIT.nano Seminar "On single photons and single molecules: From nano-quantum optics to nanobiophotonics."



Light-matter interaction at the nanometer scale lies at the heart of elementary optical processes such as absorption, emission, or scattering. Over the past two decades, Sandoghdar, one of the pioneers of the field of nano-optics, has realized a series of experiments to investigate the interaction of single photons, single molecules, and single nanoparticles.



In this presentation, Sandoghdar reports on recent studies where unity efficiency is reached in the coupling of single photons to single molecules and describe efforts to exploit this for the realization of polaritonic states involving a controlled number of molecules and photons. Furthermore, Sandoghdar shows how the underlying mechanisms that play a central role in quantum optics, help image and track single biological nanoparticles such as viruses and small proteins with high spatial and temporal resolutions.
