Professor Sahni presents a complementary perspective to Schrödinger theory of electrons in an electromagnetic field, one that does not appear in any text on quantum mechanics. Schrödinger Theory of Electrons: Complementary Perspectives (Springer Tracts on Modern Physics 285) presents ideas that reach beyond the traditional understanding of quantum theory. The book is written in a pedagogical style accessible to senior undergraduates, graduate students, and researchers in the area of electronic structure.
