This formalism includes the coupling of electron-hole pair excitations between different valence and conduction bands, originating from the electron-hole Coulomb attraction. The influence of these couplings, which are referred to as nondiagonal interband Coulomb interaction (NDI-CI), on the linear excitonic absorption spectra is investigated and discussed for light fields polarized parallel to the tube direction. The results show that the intervalley NDI-CI leads to a significant increase of the band gap and a decrease of the exciton binding energy that results in a blueshift of the lowest-frequency excitonic absorption peak. The strength of these effects depends on the symmetry of the SCNT. Furthermore, for zigzag SCNTs with higher symmetry other nonintervalley NDI-CI terms also affect the spectral positions of excitonic absorption peaks.","lang":"eng"}]},{"editor":[{"first_name":"Markus","last_name":"Betz","full_name":"Betz, Markus"},{"last_name":"Elezzabi","full_name":"Elezzabi, Abdulhakem Y.","first_name":"Abdulhakem Y."},{"last_name":"Song","full_name":"Song, Jin-Joo","first_name":"Jin-Joo"},{"first_name":"Kong-Thon","full_name":"Tsen, Kong-Thon","last_name":"Tsen"}],"status":"public","type":"conference","publication":"Ultrafast Phenomena and Nanophotonics XVIII","language":[{"iso":"eng"}],"project":[{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"_id":"15865","user_id":"16199","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"35"},{"_id":"230"},{"_id":"27"}],"year":"2014","citation":{"ama":"Lewandowski P, Ardizzone V, Tse YC, et al.

Simulations of extended multi-chromophoric systems thus require a fast but reliable approximation scheme to calculate these dipole interactions. By means of a comparative study of the dipole approximation with quantum chemistry, we demonstrate that the usual line-dipole theory, while suitable for short molecules, breaks down for longer molecules with inter-molecular separations similar to or smaller than the length of the interacting chromophores; a limit that is typically found in conjugated polymer thin films. As a remedy, we propose an improved way of distributing the sub-dipole moments within a line which provides results in very good agreement with the quantum chemistry, and is still simple enough to be used in large scale simulations.</jats:p>","lang":"eng"}],"status":"public","date_updated":"2025-12-05T14:59:12Z","publisher":"AIP Publishing","author":[{"first_name":"Jean-Christophe","full_name":"Denis, Jean-Christophe","last_name":"Denis"},{"full_name":"Schumacher, Stefan","id":"27271","last_name":"Schumacher","orcid":"0000-0003-4042-4951","first_name":"Stefan"},{"full_name":"Galbraith, Ian","last_name":"Galbraith","first_name":"Ian"}],"date_created":"2025-12-05T14:58:30Z","volume":137,"title":"Quantitative description of interactions between linear organic chromophores","doi":"10.1063/1.4768244","publication_status":"published","publication_identifier":{"issn":["0021-9606","1089-7690"]},"issue":"22","year":"2012","citation":{"ama":"Denis J-C, Schumacher S, Galbraith I.

However, here we show that the polarization-entanglement can be preserved in such a system through simultaneous emission of two degenerate photons into cavity modes tuned to half the biexciton energy. Based on detailed theoretical calculations for realistic quantum-dot and cavity parameters, we quantify the degree of achievable entanglement.","lang":"eng"}],"publication":"Optics Express","title":"Cavity-assisted emission of polarization-entangled photons from biexcitons in quantum dots with fine-structure splitting","date_created":"2018-08-21T09:03:31Z","publisher":"OSA","year":"2012","issue":"5","file_date_updated":"2018-09-04T19:10:02Z","article_type":"original","department":[{"_id":"15"},{"_id":"290"},{"_id":"230"},{"_id":"297"},{"_id":"35"},{"_id":"170"},{"_id":"34"},{"_id":"61"},{"_id":"27"}],"user_id":"16199","_id":"3974","project":[{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"status":"public","urn":"39744","type":"journal_article","doi":"10.1364/oe.20.005335","volume":20,"author":[{"last_name":"Schumacher","orcid":"0000-0003-4042-4951","id":"27271","full_name":"Schumacher, Stefan","first_name":"Stefan"},{"full_name":"Förstner, Jens","id":"158","last_name":"Förstner","orcid":"0000-0001-7059-9862","first_name":"Jens"},{"id":"606","full_name":"Zrenner, Artur","orcid":"0000-0002-5190-0944","last_name":"Zrenner","first_name":"Artur"},{"first_name":"Matthias","last_name":"Florian","full_name":"Florian, Matthias"},{"full_name":"Gies, Christopher","last_name":"Gies","first_name":"Christopher"},{"first_name":"Paul","full_name":"Gartner, Paul","last_name":"Gartner"},{"first_name":"Frank","last_name":"Jahnke","full_name":"Jahnke, Frank"}],"oa":"1","date_updated":"2025-12-16T11:12:04Z","page":"5335-5342","intvolume":"        20","citation":{"chicago":"Schumacher, Stefan, Jens Förstner, Artur Zrenner, Matthias Florian, Christopher Gies, Paul Gartner, and Frank Jahnke. “Cavity-Assisted Emission of Polarization-Entangled Photons from Biexcitons in Quantum Dots with Fine-Structure Splitting.” <i>Optics Express</i> 20, no. 5 (2012): 5335–42. <a href=\"https://doi.org/10.1364/oe.20.005335\">https://doi.org/10.1364/oe.20.005335</a>.","ieee":"S.

Using these one‐particle QD‐states, dipole and Coulomb matrix elements can be calculated, from which the optical properties of these systems can be obtained. These TB calculations have been performed for nitride‐based QDs with a cubic zincblende structure and those with a wurtzite crystal structure. In this paper, we discuss the general methodology used and the results obtained for the electronic one‐particle states and energies, for the dipole and Coulomb matrix elements, and for the excitonic optical emission and absorption spectra.</jats:p>","lang":"eng"}],"status":"public","type":"journal_article","publication":"physica status solidi (b)","language":[{"iso":"eng"}],"_id":"62929","user_id":"16199","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"35"},{"_id":"230"}],"year":"2011","citation":{"bibtex":"@article{Schulz_Mourad_Schumacher_Czycholl_2011, title={Tight‐binding model for the electronic and optical properties of nitride‐based quantum dots}, volume={248}, DOI={<a href=\"https://doi.org/10.1002/pssb.201147158\">10.1002/pssb.201147158</a>}, number={8}, journal={physica status solidi (b)}, publisher={Wiley}, author={Schulz, S. and Mourad, D. and Schumacher, Stefan and Czycholl, G.}, year={2011}, pages={1853–1866} }","mla":"Schulz, S., et al. “Tight‐binding Model for the Electronic and Optical Properties of Nitride‐based Quantum Dots.” <i>Physica Status Solidi (b)</i>, vol. 248, no. 8, Wiley, 2011, pp. 1853–66, doi:<a href=\"https://doi.org/10.1002/pssb.201147158\">10.1002/pssb.201147158</a>.","short":"S.
