WebThe fat band picture allows you to visually inspect which e-h pairs contribute the most to a particular BSE eigenstate. When k-point convergence is important, you can use it to truncate your e-h product basisset by choosing smarter NBANDSO / NBANDSV and/or OMEGAMAX values. Try NBANDSO = NBANDSV =2and check how much this effects the BSE results. http://grandcentral.apam.columbia.edu:5555/tutorials/dft_procedures/fat_bands/graphene_on_cu/vasp/index.html
WebThe fat bands F i, n, σ, k → are the periodic equivalent of the Mulliken population. They are defined as: F i, n, σ, k → = ∑ j C i, n, σ, k → C j, n, σ, k → S i, j, k →. where C i, n, σ, k … Web天玑算-科研服务丨VASP教学（10）：fatband计算与分析 21:56 天玑算-科研服务丨VASP教学（12）：部分电荷密度计算 25:36 天玑算-科研服务丨VASP教学：VASP+wannier90构建紧束缚模型（直播回放） ... 天玑算-科研服务丨QE基础操作及输运性质计算（2）：QE软件基本计算流程 ...

WebTo produce fatband plots, use the array bse_index to access the relevant quantities of the BSE eigenvectors. Note that the dimensions of the bse_index array are k points, conduction bands, valence bands and that the conduction and valence band indices may be offset by first_valence_band and first_conduction_band, respectively.
WebHere we make a fat band plot. First, follow the regular procedure for performing a band structure. The only difference is that you must add LORBIT=11 to the INCAR. We can then run fat_bands_vasp.py to extract the bands and the projections from the PROCAR; it will look in the OUTCAR of a static run for the Fermi energy (speficied on command line). building regulations underfloor ventilationWebComputational calculations based on density functional theory were used to study the structural, electronic, and magnetic properties of the AlC0.0625N0.9375 and … crown replacement dentistWebThe fat band picture allows you to visually inspect which e-h pairs contribute the most to a particular BSE eigenstate.
