The Density Matrix
... In the previous section we have looked at the possible decompositions of the density matrix in terms of convex sums of pure state density matrices. The decomposition is not unique, but the possible decompositions of the same density matrix are connected via the theorem proved in the previous section ...

AS 713 Spectroscopy in Astrophysics Fall 2014
... This course presents the physical basis for spectroscopic measurements in astronomy. We will therefore cover elementary quantum mechanics, to see where the energy levels come from, and statistical mechanics, to see what determines the strength of a spectral line. Armed with our copious knowledge, we ...
