Quantum mechanics is the most fundamental of all approaches towards understanding the nature. Quantum mechanics-II attempts to provide a introduction to some of the basic techniques used in quantum mechanics. The main objectives of the course is, to introduce the students to the theory of angular momentum and spin, to give the students a detailed exposition of the time independent non-degenerate perturbation theory, to give the students a detailed account of the time-independent degenerate perturbation theory, to give the students a working knowledge of time-dependent perturbation theory, to provide the students with a detailed solution of the Hydrogen atom problem, to introduce the students to the scattering theory, to introduce the students with the concept of semiclassical methods.

After completion of this course the students will

1)  become familiar with the theory of angular momentum, concept of spin and addition of angular momentum

2)  be able to use time-independent non-degenerate perturbation theory in order to solve physical problems

3)  be able to apply the formalism of time-independent degenerate perturbation theory to tackle physical problems

4)  be able to apply the theory of time-dependent perturbation theory in various time dependent physical problems that frequently arise

5)  have a detailed knowledge of the Hydrogen atom problem and have learned how to solve it exactly. Hydrogen atom is one of the very few real quantum systems that can be solved exactly

6)  be able to use scattering theory to predict the scattering cross sections in experiments

7)  be able to use semiclassical methods in problems where perturbation theory fails and exact quantum mechanical treatment of the problem becomes difficult

8)  This course, combined with Quantum Mechanics-I, will equip the students with the necessary understanding and tools of quantum mechanics to tackle research problems in future
