Prerequisites

LPHYS1241 or equivalent teaching unit from another program.

*The prerequisite(s) for this Teaching Unit (Unité d’enseignement – UE) for the programmes/courses that offer this Teaching Unit are specified at the end of this sheet.*
Main themes

This lecture, targeted to students being already familiar with quantum concepts and wave mechanics, will present the theory of non-relativistic quantum mechanics from its mathematical roots to its practical applications. Numerous examples will be taken from various domains such as astrophysics, atomic physics, particle physics, solid state physics, '

Content

The content of the teaching unit is the minimal required knowledge to tackle any problem involving modern non-relativistic quantum mechanics. This constitutes one of the pillar supporting the tower of competencies required for the physicist and the engineer. Various illustrations will be presented that should convince the students on how deep our society relies on quantum mechanics, examples taken from astrophysics to emerging technologies.

Lectures will start from the following tree:

' Particle in a central potential

' Formalism of Quantum Mechanics

' Angular momentum

' The hydrogen atom

' Spin

' Adding angular momentum

' Time-independent perturbation theory

' Fine an hyperfine structure of the hydrogen atom

' Time-dependent perturbation theory

' Quantum dynamics

' Introduction to path integral

Teaching methods

Teaching activities are alternating between traditional lecturing, guided learning and inquiry-based learning during the exercise sessions.

On the one hand, the traditional lectures aim at introducing, in a clear and rigorous way, the concepts that support the foundations of quantum mechanics. Illustrations will be provided in a guided learning way in order to initiate students to the cognitive reasoning of the physicist. The introduction of mathematical models, as well as the ways to solve them, will be presented in a explicit, interactive and pedestrian manner on the black board.

Exercise sessions, on the other hand, aim at the cognitive training of the students to solve a completely new problem in quantum mechanics. Problems are given one week in advance and the students are expected to work alone on these questions before showing up in class. The class itself consists in the pedestrian presentation of the solution, either by the teacher, or by the students themselves, in an inverted class.

Evaluation methods

Evaluation is based on a 4 hours long written exam that tests both the theoretical concepts presented in the teaching unit as well as their application to concrete physical problems. Basic knowledge of the teaching unit is assessed, but the main exam objective is to assess the capability of analysing and solving a new problem of quantum physics. Mastering analytical calculations and presenting coherently the corresponding results are mandatory.
