Re: Sorting of eigenvectors

Hi all, actually I take my last post back. It seems that levels also has some resorting issues. I thought its fine but if I run something like: Sys = struct('S',[1,1],'g',[2,2], 'D', [-242,-242], 'E',[762,762]); B_Fields = linspace(-5,5,200); E = levels(Sys,0,0,B_Fields); plot(B_Fields,E); I get att...

Re: Sorting of eigenvectors

Thank you Stefan, I tried eig(H) but when I plot the eigenvalues and eigenvectors as function of B-field I find some jumps/flips whenever the eigenvalues cross each other. I saw that easy spin has a levels or levelsplot that seem to not have the problem. Is there an easyspin function that returns th...

Sorting of eigenvectors

Hello everybody, I'm new to using EasySpin and am a little lost at the moment. I'm trying to pick out certain states after I run sham on sys('S', [1 1], ...) to construct the singlet state, and then calculate the projections of each state onto it. This is to calculate coefficients for singlet fissio...
