      abstract     = {Topological quantum materials have attracted enormous
                      attention since their discovery due to the observedanomalous
                      transport properties, which originate from the non-zero
                      Berry curvature. Mn3X compounds showinteresting physical
                      properties like Anomalous Hall Effect (AHE), Planer Hall
                      effect (PHE), chiral magneticeffect, 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 Mn3Xcompounds and
                      it’s 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 inMn3Sn and Mn3Ge
                      compounds.References:[1] S. Nakatsuji, N. Kiyohara and T.
