With realistic, reliable parameters which show good agreement with optical and electro-optical experiments, as well as the proper choice of Rydberg exciton states in the Cu2O crystal, we indicate how the EIT can be performed. The calculations show that, due to a large group index, one can expect the slowing down of a light pulse by a factor of about     10 4     in this medium.<\/jats:p>","DOI":"10.3390\/e22020177","type":"journal-article","created":{"date-parts":[[2020,2,5]],"date-time":"2020-02-05T03:18:48Z","timestamp":1580872728000},"page":"177","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Electromagnetically Induced Transparency in Media with Rydberg Excitons 1: Slow Light"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9908-2138","authenticated-orcid":false,"given":"David","family":"Ziemkiewicz","sequence":"first","affiliation":[{"name":"Institute of Mathematics and Physics, UTP University of Science and Technology, Al.
