Weyl Points : Berry Curvature and spin texture #68

famreenb commented 4 years ago

Hi all,

I have obtained weyl like points in a single layer transition metal system. I need to prove that those points are weyl points for which I have to get its chirality/ Z2 invariant number which will be helpful. Also the Berry curvature will also be useful in this study. I am facing difficulty in choosing the plane for bulk and slab. I am not able get the nodes as well as shown in the attached figure. Kindly help me to understand where i am doing wrong. Nodes

Hi famreenb, Weyl nodes can only be realized in 3D bulk materials. There is no 2D variant of them.
