Twisted light - new perspectives for solid state optical spectroscopy — •Florian Büscher1,2, Dirk Wulferding1,2, and Peter Lemmens1,2 — 1IPKM, TU-BS, Braunschweig, Germany — 2LENA, TU-BS, Braunschweig, Germany
Conventionally polarized light possesses zero orbital angular momentum. Using spatially modulated filters ("q-plates") [1,2] we probe the response of certain magnetic model systems to a finite orbital angular momentum, so-called twisted light [3]. We search for such effects in electronic and phononic Raman scattering and demonstrate initial results. Work supported by QUANOMET NL-4 and DFG LE967/16-1.
