Course: 2019/2020

Introductory Atomic and Molecular Physics

(15035)

Students are expected to have completed

Classical physics (Mechanics and Electromagnetism). Basic modern and quantum physics

The course is an introduction to the subject for physicists and engineers that have not taken a full course on quantum mechanics, and a preliminary to more advanced courses on atomic and molecular physics and dynamics, as a mean to acquire a heuristic comprehension of the topics. For this purpose, principal ideas of wave mechanics are introduced, followed by elementary presentations of methodological aspects, as well of descriptions of atomic and molecular structure and interactions.

Description of contents: programme

1.- Introduction to quantum mechanics. Theoretical basis of atomic and molecular physics
2.- Basic tools of quantum mechanics: wave functions, operators, Schödinger equation, stationary states, uncertainty principle
3.- Elementary applications: free particle, particle-in-a-box, harmonic oscillator
4.- Central forces. Angular momentum. One-electron atom. 5.- Approximation methods. Variational and perturbational approaches
6.- Electrons as identical particles. Spin. Many-electron atoms. Orbitals
7.- Diatomic molecules. Born-Oppenheimer approximation. Introduction to chemical bond and molecular symmetry
8.- Interaction of atoms and molecules with e.m. radiation.
