{"extern":"1","abstract":[{"text":"This paper investigates the influence of the basis set on the GW self-energy correction in the full-potential linearized augmented-plane-wave (LAPW) approach and similar linearized all-electron methods. A systematic improvement is achieved by including local orbitals that are defined as second and higher energy derivatives of solutions to the radial scalar-relativistic Dirac equation and thus constitute a natural extension of the LAPW basis set. Within this approach linearization errors can be eliminated, and the basis set becomes complete. While the exchange contribution to the self-energy is little affected by the increased basis-set flexibility, the correlation contribution benefits from the better description of the unoccupied states, as do the quasiparticle energies. The resulting band gaps remain relatively unaffected, however; for Si we find an increase of 0.03 eV.","lang":"eng"}],"issue":"4","publication":"Physical Review B","type":"journal_article","date_created":"2020-08-28T18:05:34Z","file":[{"date_created":"2020-08-28T18:07:06Z","description":"© 2006 American Physical Society","creator":"schindlm","file_id":"18600","content_type":"application/pdf","title":"Elimination of the linearization error in GW calculations based on the linearized augmented-plane-wave method","file_name":"PhysRevB.74.045104.pdf","access_level":"open_access","file_size":163641,"relation":"main_file","date_updated":"2020-08-30T15:43:33Z"}],"article_type":"original","intvolume":"        74","publication_status":"published","date_updated":"2022-11-11T06:51:40Z","author":[{"first_name":"Christoph","last_name":"Friedrich","full_name":"Friedrich, Christoph"},{"id":"458","first_name":"Arno","last_name":"Schindlmayr","orcid":"0000-0002-4855-071X","full_name":"Schindlmayr, Arno"},{"first_name":"Stefan","last_name":"Blügel","full_name":"Blügel, Stefan"},{"last_name":"Kotani","first_name":"Takao","full_name":"Kotani, Takao"}],"publication_identifier":{"issn":["1098-0121"],"eissn":["1550-235X"]},"year":"2006","title":"Elimination of the linearization error in GW calculations based on the linearized augmented-plane-wave method","doi":"10.1103/physrevb.74.045104","language":[{"iso":"eng"}],"article_number":"045104","quality_controlled":"1","citation":{"bibtex":"@article{Friedrich_Schindlmayr_Blügel_Kotani_2006, title={Elimination of the linearization error in GW calculations based on the linearized augmented-plane-wave method}, volume={74}, DOI={<a href=\"https://doi.org/10.1103/physrevb.74.045104\">10.1103/physrevb.74.045104</a>}, number={4045104}, journal={Physical Review B}, author={Friedrich, Christoph and Schindlmayr, Arno and Blügel, Stefan and Kotani, Takao}, year={2006} }","ama":"Friedrich C, Schindlmayr A, Blügel S, Kotani T.
