Since the superoperator acting on this space is also linear, the eigenvalue problem for this …
Webfunction, whereas to plot just the lowest eigenvalue it is important not to use Evaluate otherwise the wrong eigenvalue is plotted (For some reason, Plot seems to ignore Sort in this case.) The details of the functioning of the Plot com-mand, and when one should Evaluate the function to be plotted, remain rather mysterious to me. 4 matrix_qm.nb
