Note from June 29, 2020
Although we do not yet know how long the social distancing related to the Covid-19 pandemic will last, and regardless of the changes that had to be made in the evaluation of the June 2020 session in relation to what is provided for in this learning unit description, new learnig unit evaluation methods may still be adopted by the teachers; details of these methods have been - or will be - communicated to the students by the teachers, as soon as possible.

Content
Complementary to the teaching units LPHY1111, LPHY1112, LPHY 1221 and LPHY1202, which laid the foundations of classical mechanics, relativistic mechanics, electromagnetism, wave physics and mathematical methods in physics, the teaching unit provides the student with an introduction to the conceptual bases of quantum physics of the microscopic world.
The following subjects are covered in the teaching unit:
The following subjects are covered in the teaching unit:
- Discovery and observation of quantum phenomena in the microscopic world.
- Feynman probability amplitude concept.
- The Schrödinger equation.
- Examples of one-dimensional solutions and physical applications.
- The harmonic oscillator.
- The principle of linear superposition and temporal evolution.
- Uncertainty relationships.
- Quantum intricacy and Bell's theorem.
Teaching methods
The learning activities consist of lectures (ex cathedra) and practical work sessions.
The lectures are intended to introduce the fundamental concepts, to motivate them by showing examples and establishing results, to show their reciprocal links and their relations with other teaching units of the Bachelor's programme in physics.
The practical work sessions aim at learning to model phenomena of microscopic physics through quantum physics, to choose and use calculation methods for their analysis and to interpret the results obtained.
Both activities are face-to-face.

Evaluation methods
The evaluation is based on a written exam on the theoretical notions and their application to problems of the physics of the microscopic world. It tests the knowledge and understanding of the notions presented during the teaching unit, the ability to analyze a quantum physics problem, the mastery of calculation techniques and the coherent presentation of this analysis
Online resources
This teaching unit is present on MoodleUCL, where students can find the syllabus, practical exercises, historical complements and, finally, quizzes proposed during the theoretical course.
