Dear all;
if the spread becomes negative what does it mean?
I found some mistakes in my code so I edited it . but I haven't succeed to get correct WFs yet.
the flactuations in the bandstructure decreased but it is still wrong !
the spread becomes negative:
Final State
WF centre and spread 1 ( -1.171555, 0.170504, -0.083959 ) -380.61012680
WF centre and spread 2 ( 1.200799, -1.606712, -0.120351 ) -20.08399486
WF centre and spread 3 ( 0.126184, 0.772680, 2.072708 ) -384.87801891
WF centre and spread 4 ( 0.879826, 1.219855, -0.570418 ) -26.25860467
Sum of centres and spreads ( 1.035253, 0.556326, 1.297980 ) -811.83074525
Spreads (Bohr^2) Omega I = -1298.918567808
================ Omega D = 213.863027239
Omega OD = 273.224795323
Final Spread (Bohr^2) Omega Total = -811.830745246
I know the omega & omega I & D should be positive.
In this calculation only omega I is negative (Also the amoun of other omega aren't reasonable). With regard to the fact that omega I is invarient does it mean the projection is wrong?
Thanks in advance.
