Welcome to theoretical nano and quantum optics

Light at the nanoscale

We investigate light confinement and light-matter interaction at the nanoscale. By binding light to surface excitations of nanoparticles, one can squeeze light into extreme subwavelength dimensions and overcome the diffraction limit of light. This can be used for a number of applications, ranging from (bio)sensors over light harvesting to optical data processing. Over the last couple of years, we have developed the simulation toolbox nanobem that allows simulating light confinement for metallic and dielectric nanoparticles. Other related work deals with the consideration of quantum effects at small length scales and the simulation of optofluidic force induction (OF2i).

Ao.Univ.-Prof. Mag. Dr.rer.nat. Ulrich Hohenester

I am a theoretical solid-state physicist, interested in computational nanophotonics and plasmonics. I obtained my PhD in Theoretical Physics at the University of Graz 1997. I then moved as a Postdoc to the nanoscience group Modena headed by Elisa Molinari, where I spent the years 1997 - 2000 working on semiconductor quantum dots. In 2001 I joined the Solid State Theory group in Graz headed by Walter Pötz. In the same year I obtained my Habilitation in Theoretical Physics. Currently I am Professor at the Institute of Physics in Graz. From 2006 to 2016 I have been Associated Editor of the European Physical Journal B.
