The thermal and electric conductivities of different phases of water (liquid, solid, and super-ionic) occurring in the interior of ice giant planets, such as Uranus or Neptune, are evaluated from equilibrium ab initio molecular dynamics, leveraging recent progresses in the theory and data analysis of transport in extended systems. In this record we collect the ab-initio time series of the energy flux and of the electronic and ionic charge fluxes for H2O at different planetary conditions, from which the related transport coefficients are extracted according to the Green-Kubo theory of linear response.</dc:description> <dc:identifier>https://archive.materialscloud.org/record/2020.73</dc:identifier> <dc:identifier>doi:10.24435/materialscloud:hn-6f</dc:identifier> <dc:identifier>mcid:2020.73</dc:identifier> <dc:identifier>oai:materialscloud.org:448</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>Transport properties</dc:subject> <dc:subject>Molecular dynamics</dc:subject> <dc:subject>Water at extreme conditions</dc:subject> <dc:subject>Planetary evolution models</dc:subject> <dc:subject>MaX</dc:subject> <dc:title>Heat and charge transport in H2O at ice-giant conditions from ab initio molecular dynamics simulations</dc:title> <dc:type>Dataset</dc:type> </oai_dc:dc>
