hi i am doing electron phonon calculations and Tc. i slowly increase the k-grid and q-grid as must as i can afford and try to converge lambda. i wonder what is the convergence level for lambda value? what should the difference in lambda values be to consider lambda as converged? typical lambda values for degauss 0.005~0.05 below:
1.16890 0.80866 0.72623 0.69491 0.67781 0.66805 0.66393 0.66451 0.66891 0.67648 should i go further increasing grid or is it converged at 6th value 0.66~ thank you Bahadir Altintas,PhD SUNY Buffalo,NY Dept. of Chemistry
