Dear all, Thank you so much for your kind response. I am trying to calculate the band structure of NiO (LDA+U). Here I am attaching the link of band structure and band.in the input file. https://drive.google.com/drive/folders/1ov3FI8cVJPE9ch96g8QPs2PFZU_4iGlG The high symmetry path I calculated using the CIF file and seek path: https://materialsproject.org/materials/mp-19009/# https://www.materialscloud.org/work/tools/seekpath I want to math this band structure with some paper. On the materials cloud, the path is given that is different from my one. Here I am attaching the link of paper in where I observed the band structure of NiO (LDA+U) but the path is different from my one https://journals.aps.org/prb/pdf/10.1103/PhysRevB.71.035105 .......fig(13) Also, I observed the same path but my band structure is different than as compare to this band structure (below is the link) https://matgenb.materialsvirtuallab.org/2013/01/01/Bandstructure-of-NiO.html I
Two more curiosity: 1). I would like to plot the band structure for the spin-down state also, as mentioned here in the input file https://matgenb.materialsvirtuallab.org/2013/01/01/Bandstructure-of-NiO.html I defined nspin=2. Is anything else I suppose to do for obtaining the data for the spin-down state. 2). In the band. in the input file, I have discontinuous path G X U|K G L W X and I defined in the input file as like below I mentioned. I learned this by reading some previous questions on the forum, between two high symmetry points I took 20 points. I have confusion in between X and U I took 0 points, is this correct for defining such type of path. K_POINTS {crystal_b} 8 0.0000000000 0.0000000000 0.0000000000 20 !G 0.5000000000 0.0000000000 0.5000000000 20 !X 0.6250000000 0.2500000000 0.6250000000 0 !U 0.3750000000 0.3750000000 0.7500000000 20 !K 0.0000000000 0.0000000000 0.0000000000 20 !G 0.5000000000 0.5000000000 0.5000000000 20 !L 0.5000000000 0.2500000000 0.7500000000 20 !W 0.5000000000 0.0000000000 0.5000000000 20 !X I'll be very thankful for giving me the correct direction for all these confusions.
