Electronic correlations and flattened band in magnetic Weyl semimetal candidate Co3Sn2S2

How electron correlation interplays with topological states remains rarely explored. Here, the authors report flat band arising due to electron correlations in magnetic Weyl semimetal Co3Sn2S2 from a combined optical-spectroscopy and simulation study.
