Course Importance: This undergraduate course develops concepts in quantum mechanics that can be understood from a fundamental point of view. It provides a basis for further study of quantum mechanics as in previous semester Quantum Mechanics-I is already being offered to the students. The main emphasis of this course will be to understand the quantum concepts regarding angular momentum, solution of Schrodinger equation in three dimensions (Cartesian Coordinates, Spherical Coordinates, and Hydrogen Atom), approximation methods for stationary states, theory of scattering and identical particles.

Learning Outcomes: This course examines the fundamental concepts and techniques of quantum mechanics. Students will develop a self-critical perspective on the theoretical techniques to solve the problems. Rather the task is to develop reflective and critical skills for thinking about creative solutions to for further higher studies and applications.

Course Contents:

1. Orbital angular momentum, The eigenvalues and eigen-functions of L2 and Lz, Matrix representation of angular, momentum operators, Addition of angular momenta. Schrödinger Equation in Three Dimensions (3D problems in Cartesian and Spherical coordinates).

2. Approximate Methods (Time independent perturbation theory for non degenerate and degenerate levels, the variational method, The WKB approximation, Time dependent perturbation theory).

3. Identical Particles and Second Quantization (Many Particles Systems, Systems of Identical Particles, The Pauli Exclusion Principle).

4.Theory of Scattering, The Interaction of Quantum Systems with Radiation (Classical Treatment of Incident Radiation, Quantization of the electromagnetic Field, Transition Rates for Absorption and Emission of Radiation, Transition Rates within the Dipole, The Electric Dipole Selection Rules).
