This unified approach describes both conventional and unconventional superconducting states, and enables a description of inhomogeneous superconductors and heterostructures. We demonstrate the validity, accuracy, and efficiency of SIESTA-BdG by computing physically relevant quantities (superconducting charge density, band structure, superconducting gap features, density of states) for conventional singlet (Nb, Pb) and unconventional (FeSe) superconductors. We find excellent agreement with experiments and results obtained within the KKR-BdG computational framework. SIESTA-BdG forms the basis for modelling quantum transport in superconducting devices and including - in an approximate fashion - the superconducting DFT potential of Oliveira, Gross, and Kohn. This dataset contains the calculations performed on bulk Nb and the associated notebooks used to generate figures from this data.</dc:description> <dc:identifier>https://archive.materialscloud.org/record/2024.143</dc:identifier> <dc:identifier>doi:10.24435/materialscloud:3k-4e</dc:identifier> <dc:identifier>mcid:2024.143</dc:identifier> <dc:identifier>oai:materialscloud.org:2358</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>Superconductivity</dc:subject> <dc:subject>Bogoliubov-de Gennes</dc:subject> <dc:subject>SIESTA</dc:subject> <dc:subject>Nb</dc:subject> <dc:subject>AiiDA</dc:subject> <dc:subject>AiiDA-Siesta</dc:subject> <dc:subject>PRACE</dc:subject> <dc:subject>Horizon Europe</dc:subject> <dc:subject>MaX</dc:subject> <dc:subject>H2020</dc:subject> <dc:subject>Marie Curie Fellowship</dc:subject> <dc:title>Density functional Bogoliubov-de Gennes theory for superconductors implemented in the SIESTA code</dc:title> <dc:type>Dataset</dc:type> </oai_dc:dc>
