Condensed-Matter Physics & Materials Science Seminar
"Focusing Light with an Atomic Lens"
Presented by Jack Griffiths, University of Cambridge, United Kingdom

Nanometer scale gaps between gold nanoparticles and gold surfaces confine light far below the diffraction limit and enhance optical intensities by x10^5. These plasmonic cavities augment all light-matter interactions including fluorescence, inelastic vibrational scattering and the onset of light-matter strong coupling. Here, we will discuss the physics of this confinement and how it can be leveraged for such differing tasks as low concentration drug detection and forming low energy color e-ink displays.
Atomic scale protrusions from the metal act as lightning rods to further confine light to
