报告人简介：

Professor Yi Luo received hisPhD in computational physics (1996) from Linköping University. He is currentlythe Director of Hefei National Laboratory for Physical Sciences at theMicroscale, University of Science and Technology of China (USTC). He had been aProfessor in the Royal Institute of Technology (KTH), Sweden, before wasrecruited by the Thousand Talents Program of China. He was awarded the GöranGustafsson Prize in chemistry from the Royal Swedish Academy of Sciences, andthe Outstanding Science and Technology Achievement Prize from Chinese Academyof Sciences. He has published more than 500 papers, with total citations morethan 16000, and H-index 63.

报告内容简介：

Due to the diffraction limit, the opticalresolution of a far field light is less than a half of its wavelength, whichmakes it virtually impossible to “see” subject at the nanoscale. The use of a metallic nanocavity cangenerate spatially highly confined plasmon with intense field of broad energydistribution. It can break the diffraction limit to visualize a single moleculein real space[1]. The use of nanocavity plasmon (NCP) has also led to thediscoveries of plasmonic enhanced stimulating emission[2a], coherent energytransfer[2b], and plasmon induced nonlinear electron scattering[2c]. A newtheory that describes the interaction between the nanosized light and themolecule has been fully developed [3].
