This book is a comprehensive text in the field of quantum mechanics,
covering fundamental concepts including the state of a quantum
mechanical system, operators, superposition principle and measurement
postulate. The notion of an operator and the algebra of operators are
introduced with the help of elementary concepts of mathematical
analysis. Mathematical tools developed will help readers in
understanding the difficulties encountered in classical physics while
trying to explain the experimental results involving atomic spectra and
other phenomena. The differential equations that arise while solving
eigenvalue problems are solved rigorously, to make the text
self-sufficient. The solutions are then physically interpreted and
explained. The text offers solved examples, analogous and homework
problems to help students in solving practical problems of physics
requiring quantum mechanical treatment.
