Quantum Mechanics and Applications by Prof. Ajoy Ghatak, Department of Physics, IIT Delhi. For more details on NPTEL visit http://nptel.iitm.ac.in

## Course Description :

Basic mathematical preliminaries:Dirac Delta function and Fourier Transforms.

Wave particle duality, one- and three- dimensional Schrödinger equation. The free particle problem in one dimension. Wave Packets and Group velocity.

One-dimensional problems: Potential well of infinite and finite depths, the linear harmonic oscillator.

Angular Momentum and rotation.

Three-dimensional Schrödinger equation: Particle in a box with applications to the free electron model. Particle in a spherically symmetric potential problem. The hydrogen atom and the deuteron.

(A numerical method to obtain solutions of the Schrödinger equation will also be discussed and a software to understand basic concepts in quantum mechanics will also be demonstrated).

Dirac’s bra - ket algebra; Linear Harmonic Oscillator problem using bra - ket algebra, creation and annihilation operators, transition to the classical oscillator, Coherent states.

The angular momentum problem, using bra - ket algebra, ladder operators and angular momentum matrices. The Stern Gerlach and magnetic resonance experiments. Addition of Angular Momenta and Clebsch Gordon coefficients.

Perturbation Theory with applications; The JWKB approximation with applications; Scattering Theory: Partial Wave Analysis.
