Carbon nanotubes have reached a quality that allows for stringent tests of theory. Applying high magnetic fields we perform transport spectroscopy on the first excess electron above the band gap. The observed single particle spectra allow to quantitatively probe the fine structure corrections to the simple Dirac Hamiltonian.
Recent experimental developments in nanophotonics , circuit QED  and cold atoms  allow to engineer systems where quantum emitters couple to low dimensional photon-like reservoirs with non-trivial energy dispersions.

The idea of studying strong matter-light coupling using organic molecules has a long history, but has recently seen an explosion of experimental interest. In particular exciton-polariton lasing and condensation has now been observed in a variety of organic media, including anthracene, organic polymers, and fluorenes.

When photoactive molecules strongly interact with confined light, for instance inside optical cavities or near (localised) surface plasmons, new hybrid light-matter states may form, the so-called polaritons or plexcitons.
