Among the different sources available, semiconductor quantum dots excel with their integrability in semiconductor on-chip solutions and the potential that photon emission can be triggered on demand. Usually, the photon is emitted from a single-exciton ground state. Polarization of the photon and time of emission are either probabilistic or pre-determined by electronic properties of the system. Here, we study the direct two-photon emission from the biexciton. The two-photon emission is enabled by a laser pulse driving the system into a virtual state inside the band gap. From this intermediate state, the single photon of interest is then spontaneously emitted. We show that emission through this higher-order transition provides a versatile approach to generate a single photon. Through the driving laser pulse, polarization state, frequency and emission time of the photon can be controlled on-the-fly.}}, author = {{Heinze, Dirk and Breddermann, Dominik and Zrenner, Artur and Schumacher, Stefan}}, issn = {{2041-1723}}, journal = {{Nature Communications}}, number = {{1}}, publisher = {{Springer Nature}}, title = {{{A quantum dot single-photon source with on-the-fly all-optical polarization control and timed emission}}}, doi = {{10.1038/ncomms9473}}, volume = {{6}}, year = {{2015}}, } @article{22946, abstract = {{The Kane–Mele model was previously used to describe effective spin–orbit couplings (SOCs) in graphene.

For chiral semiconducting CNTs with large chiral angle we show that the spin-splitting configuration of bands near the Fermi energy depends on the value of $\text{mod}(2n+m,3)$ .}}, author = {{Liu, Hong and Heinze, Dirk Florian and Thanh Duc, Huynh and Schumacher, Stefan and Meier, Torsten}}, issn = {{0953-8984}}, journal = {{Journal of Physics: Condensed Matter}}, number = {{44}}, title = {{{Curvature effects in the band structure of carbon nanotubes including spin–orbit coupling}}}, doi = {{10.1088/0953-8984/27/44/445501}}, volume = {{27}}, year = {{2015}}, } @article{13922, author = {{Liu, Hong and Heinze, Dirk Florian and Thanh Duc, Huynh and Schumacher, Stefan and Meier, Torsten}}, issn = {{0953-8984}}, journal = {{Journal of Physics: Condensed Matter}}, number = {{44}}, title = {{{Curvature effects in the band structure of carbon nanotubes including spin–orbit coupling}}}, doi = {{10.1088/0953-8984/27/44/445501}}, volume = {{27}}, year = {{2015}}, } @article{15860, author = {{Denis, Jean-Christophe and Schumacher, Stefan and Hedley, Gordon J. and Ruseckas, Arvydas and Morawska, Paulina O. and Wang, Yue and Allard, Sybille and Scherf, Ullrich and Turnbull, Graham A. and Samuel, Ifor D.
