This week the @MatMat group takes part in the #psik conference (https://www.psik2025.net/) at #epfl with plentey of cutting-edge talks on #materials #modeling and simulations of #condensedmatter. My contribution has been a short talk on #error quantification and propagation in #densityfunctionaltheory simulations leveraging the built-in #automaticdifferentiation framework of the #dftk code for automatic gradient computation.
