Hi everyone,<div><br></div><div>In pp.x, it says that if we set plot_num=0, we can get a file of "charge" and if plot_num equals to 9, we can get "reduced density gradient". What do 'charge' and 'density' here mean? Are they only related to the electrons that the pseudopotential files count? If we replace the charge density variable in Poisson equation and solve it, what can we get for the 'potential'?</div>
