Self-energy calculations in the GW approximation show that the inclusion of self-consistency in the Green function G and the screened Coulomb potential W opens the band gap far stronger than found in previous G0W0 calculations but slightly overestimates its actual value due to the neglect of excitonic effects in W. A realistic frozen-lattice band gap of about 5.9 eV is obtained by combining hybrid density functional theory with the QSGW0 scheme. The renormalization of the band gap due to electron-phonon coupling, derived here using molecular dynamics as well as density functional perturbation theory, reduces this value by about 0.5 eV at room temperature. Spin-orbit coupling does not noticeably modify the fundamental gap but gives rise to a Rashba-like spin texture in the conduction band.","lang":"eng"}],"article_number":"075205","language":[{"iso":"eng"}],"doi":"10.1103/PhysRevB.93.075205","title":"LiNbO3 electronic structure: Many-body interactions, spin-orbit coupling, and thermal effects","year":"2016","publication_identifier":{"issn":["2469-9950"],"eissn":["2469-9969"]},"author":[{"full_name":"Riefer, Arthur","last_name":"Riefer","first_name":"Arthur"},{"full_name":"Friedrich, Michael","first_name":"Michael","last_name":"Friedrich"},{"first_name":"Simone","last_name":"Sanna","full_name":"Sanna, Simone"},{"first_name":"Uwe","orcid":"0000-0002-4476-223X","last_name":"Gerstmann","full_name":"Gerstmann, Uwe","id":"171"},{"id":"458","first_name":"Arno","orcid":"0000-0002-4855-071X","last_name":"Schindlmayr","full_name":"Schindlmayr, Arno"},{"first_name":"Wolf Gero","last_name":"Schmidt","orcid":"0000-0002-2717-5076","full_name":"Schmidt, Wolf Gero","id":"468"}],"publication_status":"published","date_updated":"2025-12-05T09:59:57Z","article_type":"original","intvolume":"        93","external_id":{"isi":["000370794800004"]},"oa":"1","file_date_updated":"2020-08-30T14:39:23Z","citation":{"apa":"Riefer, A., Friedrich, M., Sanna, S., Gerstmann, U., Schindlmayr, A., &#38; Schmidt, W.

The phonon density of states of the ferroelectric (paraelectric) phase shows two (one) distinct band gaps separating the high-frequency (~800 cm−1) optical branches from the continuum of acoustic and lower optical phonon states. This result leads to specific heat capacites in close agreement with experimental measurements in the range 0–350 K and a Debye temperature of 574 K. The calculated zero-point renormalization of the electronic Kohn–Sham eigenvalues reveals a strong dependence on the phonon wave vectors, especially near Γ. Integrated over all phonon modes, our results indicate a vibrational correction of the electronic band gap of 0.41 eV at 0 K, which is in excellent agreement with the extrapolated temperature-dependent measurements.","lang":"eng"}],"date_created":"2019-05-29T08:41:18Z","file":[{"description":"© 2015 IOP Publishing Ltd","date_created":"2020-08-28T14:24:23Z","creator":"schindlm","title":"Phonon dispersion and zero-point renormalization of LiNbO3 from density-functional perturbation theory","content_type":"application/pdf","file_id":"18578","date_updated":"2020-08-30T14:46:56Z","relation":"main_file","file_size":1793430,"access_level":"closed","file_name":"Friedrich_2015_J._Phys. _Condens._Matter_27_385402.pdf"}],"department":[{"_id":"295"},{"_id":"296"},{"_id":"230"},{"_id":"429"},{"_id":"15"},{"_id":"35"},{"_id":"27"}],"type":"journal_article"},{"author":[{"full_name":"Sanna, S.","last_name":"Sanna","first_name":"S."},{"full_name":"Dues, C.","last_name":"Dues","first_name":"C."},{"id":"468","full_name":"Schmidt, Wolf Gero","orcid":"0000-0002-2717-5076","first_name":"Wolf Gero","last_name":"Schmidt"}],"publication_identifier":{"issn":["0927-0256"]},"title":"Modeling atomic force microscopy at LiNbO 3 surfaces from first-principles","year":"2015","status":"public","intvolume":"       103","date_updated":"2025-12-05T10:37:16Z","publication_status":"published","language":[{"iso":"eng"}],"_id":"13504","page":"145-150","volume":103,"doi":"10.1016/j.commatsci.2015.03.025","user_id":"16199","citation":{"apa":"Sanna, S., Dues, C., &#38; Schmidt, W.

Usually, the photon is emitted from a single-exciton ground state.\r\nPolarization of the photon and time of emission are either probabilistic or pre-determined by\r\nelectronic properties of the system. Here, we study the direct two-photon emission from the\r\nbiexciton. The two-photon emission is enabled by a laser pulse driving the system into a\r\nvirtual state inside the band gap. From this intermediate state, the single photon of interest\r\nis then spontaneously emitted. We show that emission through this higher-order\r\ntransition provides a versatile approach to generate a single photon. Through the driving\r\nlaser pulse, polarization state, frequency and emission time of the photon can be controlled\r\non-the-fly.","lang":"eng"}],"date_created":"2018-08-30T13:07:30Z","type":"journal_article","department":[{"_id":"15"},{"_id":"230"},{"_id":"35"},{"_id":"170"},{"_id":"429"}]},{"date_created":"2019-03-29T13:43:44Z","type":"journal_article","department":[{"_id":"230"},{"_id":"429"}],"publication":"Physical Review B","citation":{"ieee":"S.
