Sinéad Majella Griffin (born July 20, 1986) is an Irish physicist working at Lawrence Berkeley National Laboratory on condensed matter physics and materials science.
[2] She moved to Imperial College London for her master's studies, working with Ray Rivers on topological defects in condensed matter and cosmology.
[4] When Nicola Spaldin joined ETH Zurich, Griffin accompanied her, earning a PhD, in 2014 looking at the Hubbard model for hexagonal manganites.
[6] She won the 2015 Materials and Processes (MaP) Award for the best interdisciplinary thesis at ETH Zurich.
[14] In the same year, Griffin published an arXiv preprint, presenting density functional theory augmented with a on-site Hubbard-like model (i.e., DFT+U) calculations of Cu-substituted lead phosphate apatite (i.e., suspected structure of LK-99), identifying correlated isolated flat bands at the Fermi level, a debated[15] signature of superconductors.
