The 2nd data output relates to your ldos range. So they are effectively not equivalent. The first is the final scf, the 2nd ldos. I think this is the case, but I am not 100 sure (not at my computer to check). On Tue, 21 Jun 2022, 22:00 I. Camps, wrote: > I completely agree with Tamas and

Dear Camps, Emilio, True, I overlooked the point in the original question (my apologies!) but thought that the doubling of charge prints is simply due to a spin polarized calculation. I was wrong, as that doubling also appears in case of closed shell singlets' outputs. What is more, the two

I completely agree with Tamas and Emilio BUT my question *is not* related to which charge calculation scheme is "better". My question is that in my calculations, two different sets of data of the same type of charges are appearing in the output file, instead only one for each. I have two outputs

Tamas’s reply is correct, I just want to add a reminder of the fact that atomic charges have a fundamental definition problem and none of the proposals gives the ‘good’ answer. This is a direct consequence of its responding to an ill-posed question: how many electrons ‘belong’ to a given atom (or

Dear Camps, Please note that an argument is going on for decades about how to calculate atomic charges. Different methods/schemes give different results, each is giving better/worse results for different applications. It is recommended to check how well each performs at your actual problem and

Hi, I cannot reproduce your results. Which version of Siesta are you using? Can you show your output? The expected behavior is something like this (obtained with the 4.1 branch version): [...] siesta: Electric dipole (a.u.) = -0.000.558297 -0.00 siesta: Electric dipole
