Toward Atomic-Scale Optical Spectroscopy in Plasmonic STM Junctions — •Takashi Kumagai — Fritz-Haber Institute of the Max-Planck Society — Laureate of the Gaede Prize 2020

Light-matter interactions can be largely enhanced in the presence of optical near fields. Atomic-scale light-matter interactions in plasmonic 'picocavities' has emerged as a new frontier of fundamental physics [1]. The investigation of such light-matter interactions involves significant challenges for both experiment and theory. A combination of plasmon-enhanced spectroscopy with low-temperature STM can provide a unique way to investigate intriguing physics resulting from the strong interaction between cavity-mode plasmon and matter. I will show our recent development toward atomic-scale optical spectroscopy in plasmoic STM junctions [2-5]. References: [1] Science 354, 726 (2016). [2] PRL 121, 226802 (2018). [3] J. Phys. Chem.
