Confining light to the sub-atomic scale: watching atoms, electrochemistry, catalysis, and sensing

Jeremy Baumberg, Professor, Physics, University of Cambridge,

**Pizza Lunch for attendees on Watson Patio directly following talk

Abstract:

What is the smallest volume that light can be confined to? What is the largest refractive index that a metamaterial can support? Can we create plasmonic sensors without any contamination from organic surfactants or lithographies, and that can be reused? In this talk I will answer these questions and more, as I survey recent progress in extreme light confinement. I will also explore applications in precision healthcare, electrocatalysis, agritech, and environmental protection.

More about the Speaker:

Professor Jeremy J. Baumberg FRS, leads a UK Centre for Nanotechnology at the University of Cambridge. He has also worked in industries including Hitachi, IBM, and his own spin-offs. His popular science book "The Secret Life of Science: How Science Really Works and Why it Matters" (2018) was published by PUP. He has won many awards including the IoP Faraday gold Medal (2017) and Royal Society Rumford Medal (2014). He advises government funders as chair of UK EPSRC Council and advisor to ARIA.
