Light Steering Matter

Trapping matter with light and manipulating it at the same time might appear like a nerve-wrecking science-fiction scene from a Hollywood movie.…

(left) Experimental momentum maps of PTCDA on MgO(001) at increasing photon energy. The pattern changes with photon energy as a result of the bent carbon backbone of PTCDA. (right) Side view in real space and three-dimensional momentum space density of the calculated highest occupied molecular orbital of PTCDA on MgO(001). The grey sphere represents the cut through the 3D momentum space density at a certain photon energy, which is measured experimentally as 2D momentum map. Image: UniGraz/Sterrer
