Professor Frank Cichos, Leipzig University

 

"Thermoplasmonics - Heat for Molecules and Particles"

The ability to release heat on the nanoscale has recently gained large attention in various fields of science including biophysics, chemistry, and medicine [1]. Noble metal nanostructures thereby serve as a key element with their plasmonic resonances that couple efficiently to light to provide precise local control of temperature and temperature gradients. This gives rise to new applications but also poses new physical questions. 

In this talk, I will discuss the fundamental processes that allow us to control single molecules, colloids, and other materials with the help of dynamic temperature fields. I will show how to use the control of local temperature in liquids to elucidate processes of protein aggregation and how to employ sophisticated feedback control to gain insights into the emergent collective behavior of active particles.
