We consider two functionals, the γDFT and the μDFT functionals, both of which are based on the addition of a weak local potential to the semilocal Hamiltonian to enforce the piecewise-linearity condition. We show that the resulting polaron properties are in good agreement with reference hybrid functional calculations. This supports the use of semilocal functionals for calculating polaron properties.</dc:description> <dc:identifier>https://archive.materialscloud.org/record/2024.47</dc:identifier> <dc:identifier>doi:10.24435/materialscloud:36-ww</dc:identifier> <dc:identifier>mcid:2024.47</dc:identifier> <dc:identifier>oai:materialscloud.org:2115</dc:identifier> <dc:language>en</dc:language> <dc:publisher>Materials Cloud</dc:publisher> <dc:rights>info:eu-repo/semantics/openAccess</dc:rights> <dc:rights>Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/legalcode</dc:rights> <dc:subject>density-functional theory</dc:subject> <dc:subject>polarons</dc:subject> <dc:subject>piecewise linearity</dc:subject> <dc:subject>γDFT</dc:subject> <dc:subject>μDFT</dc:subject> <dc:subject>self-interaction</dc:subject> <dc:title>Nonempirical semilocal density functionals for correcting the self-interaction of polaronic states</dc:title> <dc:type>Dataset</dc:type> </oai_dc:dc>
