      abstract     = {Topological quantum materials have garnered considerable
                      attention since their discovery, owing to the observed
                      anomalous transport properties that originate from their
                      non-zero Berry curvature. Mn3X compounds show interesting
                      physical properties like Anomalous Hall Effect (AHE), Planar
                      Hall effect (PHE), chiral magnetic effect, and non-local
                      transport properties due to non-vanishing Berry flux
                      emerging from the Weyl points1. It is widely believed that
                      the magnetic structure and Weyl properties are intimately
                      connected.However, the observation of negative longitudinal
                      magnetoresistance (LMR), AHE, and PHE in Mn3X compounds and
                      its connection with the chiral magnetic effect is much
                      debated in the literature. In this talk, I will give a brief
                      overview of the current understanding of the negative LMR,
                      AHE, and PHE as observed in Mn3Sn and Mn3Ge
                      compounds.References:[1] S. Nakatsuji, N. Kiyohara and T.
