报告人：Professor Hans Ågren,Department of Physics and Astronomy, Uppsala University 

报告人简介：

Prof. Hans Ågren is currently leading a research group at the Department of Physics and Astronomy, Uppsala University, Sweden. He received his doctoral degree in experimental atomic and molecular physics in 1979 from Uppsala University and then worked as a postdoctoral researcher at IBM Research Laboratory in the United States. He has successively held chair professorships at Linköping University, KTH-Royal Institute of Technology and Uppsala University. In 2016, he received the “Changjiang Distinguished Professorship” from the Ministry of Education of China. His research interests are mainly focused on developing theoretical methods for studying nonlinear optics, lasers, X-rays, magnetic resonance, nanomaterials, and multi-scale simulations. Up to now his work has received more than 48000 citations according to Google Scholar with an h-factor of 100.

摘要：

In this seminar he will present two short talks. The first concerns ultrafine plasmonic nanoparticles which are particularly useful in the areas of biosensing and imaging. In order to bridge the gap between quantum (< 1nm) and classical dielectric (>10 nm) models he earlier derived a semi-empirical discrete interaction model to design such  particles and  used it in benchmark studies concerning size, shape, material and temperature dependence. He more recently derived a quantum mechanics – plasmonics mechanics multiscale method joining quantum and classical physics to study plasmonically induced molecular properties.  He will show a set of application examples of these models.

In the second talk he will discuss some recent progress in the theme of photophysics using organic radicals coming from the group of Dr Glib Baryshnikov, Laboratory of Organic Electronics at Linköping University. A set of rapidly generated, ultra-stable, and switchable photoinduced radicals  are shown as examples, where their emissive properties are studied by computational modelling.
