Quantum physics I
Summary
The objective of this course is to familiarize the student with the concepts, methods and consequences of quantum physics.
Content
1. A bit of history: the crisis of classical physics
2. The Stern and Garlach experiment: quantum states and spin 1/2
3. The axioms of quantum physics: state vectors, operators, measurement, representations
4. Continuous degrees of freedom: translation operator and canonical quantization
5. Time evolution: Schrödinger's equation and Heisenberg's point of view
6. Some simple problems in one dimension
7. Central potentials, angular momentum and hydrogen atom
8. Composite systems: entanglement and Bell's inequalities
9. Addition of angular momentum
Keywords
Quantum mechanics, Schrödinger equation, Heisenberg uncertainty principle, wave function, harmonic oscillator, hydrogen atom, spin, entanglement
Learning Prerequisites
Required courses
Basic physics and mathematics undergraduate courses
Important concepts to start the course
Strong working knowledge of calculus and linear algebra (covered in basic math courses).
Learning Outcomes
By the end of the course, the student must be able to:
- Explain the difference between classical and quantum physics
- Compare Schrödinger's and Heisenberg's viewpoints on quantum physics
- Derive Heisenberg's uncertainty principle
- Solve the quantum harmonic oscillator with the ladder operator method
- Interpret the measurement process in quantum physics
- Solve Schroendinger's equation for problems in 1,2 and 3 dimensions
- Characterize the amount of entanglement in a two-spin system
- Contextualise the postulates of quantum physics
Teaching methods
Ex cathedra. Exercises prepared in class.
Expected student activities
Students are expected to regularly attend the theory lectures and the exercise lectures. They are also expected to complete the exercises that are given on a weekly basis, as well as regularly study the learning material offered by the professor (lecture notes, exercises solutions etc).
Assessment methods
Written exam
