The theory of atoms, molecules and solids is largely dependent on good approximate solutions to appropriate quantum mechanical many-electron systems. Thus the appearance in recent years, of a new practical way to generate such solutions has met with considerable interest. The method is the density-functional method (DFT) in the local density approximation (LDA). . . . R.G. Parr and W. Yang are experienced professionals in this area . . . Their book is a thorough and solid introduction to the DFT. . . . I found the book well written, accurate and helpful. I recommend it.
