It is recommended that students start Quantum Physics meeting a few reasonable prerequisites. One has to take into account that quantum physics is one of the most difficult subjects in physics, either because of its anti-intuitive and very broad content (it affects many parts of physics), or because it involves several sophisticated mathematical tools:
Physics: Knowledge of classical mechanics including, at an elementary level, Hamiltonian formulism; Knowledge of electromagnetism, waves and first-year optics
Mathematics: knowledge of algebra, including vector spaces (with metrics), linear operators and eigenvectors and eigenvalues; elementary knowledge of complex numbers, integration of functions of several variables, and differential equations.
General: it takes an open mind and an ability (training) to keep up with the course work that involves formal and conceptual difficulties.
The aim is to introduce students to the world of quantum mechanics, which is an essential part of modern physics. To expose them and to help them reach the fundamental concepts and the basic formalism of this discipline. Illustrate its usefulness, importance and meaning with applications. To provide a training to tudents that will allow them to deepen and broaden their knowledge in Quantum Physics II and in the optional subjects of Quantum Mechanics, Advanced Quantum Mechanics, Quantum Information, Quantum Optics, among others.
The (no-exhaustive) list of basic objectives is:
(i) Know the experiments that gave birth to quantum mechanics
(ii) Identify the quantum formulation and postulates in finite and infinite dimensional systems.
(iii) Make temporal evolutions in spaces of finite dimension (essentially dimension 2)
(iv) Know the wave formulation in space of coordinates and moments
(v) Solve the energy spectrum and states of simple 1D potentials (wells and harmonic oscillator) in wave mechanics
(vi) Description of collision states (scattering) in simple potential barriers and know the differences with bound states
(vii) Knowing how to make the temporal evolution of a free wave packet.
(viii) Solve simple problems in 3D (infinite well and isotropic and non-isotropic harmonic oscillator). Analyze degeneracies.
(ix) Sovle problems with radial symmetry, Laplacian expressions and orbital angular momentum.
(x) Solve the spectrum of the hydrogen atom

Theory lectures: In the theory classes we introduce the key concepts and methods that define the contents of the subject. Before each class the students must become familiar with the subject, making us of the material (notes, videos or bibliography) that will be made available to them.
Problem sessions: The exercises illustrate the application of the concepts learned to specific problems of pedagogical or practical relevance. They should also serve the student to strengthen her or his mathematical skills.
A part of the problems are solved in class by the teacher, so that the students -who will have previously attempted to solve the problems at home- can know the degree of success of their solutions and incorporate the pertinent corrections; other problems must be solved and delivered by the student directly to the teacher. The latter will be done in the form of home deliveries.
There are scheduled four sessions of 2 hours each where problems are done in groups of 3-4 randomly assigned students. These problems deal with some aspects in a more exhaustive way and allow to illustrate the application of concepts in more depth as well as to learn some new techniques.
Tutoring: The individual tutorials (eventually it will be possible to organize some in group) can be used to solve any issues or difficulties.
Home activities:
Study and preparation of Theory classes.
Study and resolution of problems.
Peer reviewing of projects
Additional considerations
The creation of a SLACK workspace to facilitate communication between different groups of students and teachers will be considered.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.
Title | Weighting | Hours | ECTS | Learning Outcomes |
---|---|---|---|---|
Assignment i and problem Sessions | 10-15% | 0 | 0 | 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 |
First evaluation | 42.5-45% redeemable | 3 | 0.12 | 2, 3, 5, 6, 8, 9 |
Make up exam | 100% | 3 | 0.12 | 1, 2, 3, 4, 6, 7, 8, 9 |
Second evaluation | 42.5-45% redeemable | 3 | 0.12 | 1, 3, 4, 5, 6, 7, 8, 9 |
All evaluations will be written. Exams will be split into a Theory and Problems part of the same weight. Support texts may not be used during the exams, except for a formulary that will either be attached to the exam or prepared beforehand by the student. The first evaluation (with Theory and Problems) will be done after about 7 weeks and will include approximately half of the syllabus. The second will be done about 7 weeks later and will include the other half.
Both the first and the second partial exams will be redeemable (and with the possibility to improve the grade) at the end of the semester with a final evaluation or make up exam. In other words, there will be two partial exams and for those who want it or need it, there will be a make-up exam for the relevant parts. It is necessary to have a grade of at least 3 for each of the parts. In general, it is necessary to sit in both partials in order to be able to take the make-up exam. Special circumstances may be considered. The assignements and problem sessions will contribute up to one point (or depending on the workload, up to a point and a half) to the mark of the partial examinations (not to the one of make-up exam). The student will be considered evaluatable if any of the partial or final examinations are handed in.
With respect to students approved for partials who present themselves to upload a grade (of the partials or overall), if the grade is higher than the previous one, the latter will be considered, and if it is lower, an average will be made at 75% previous grade 25% recovery grade.
Singleassessment
Students who have requested the single assessment modality will have to take a final test which will consist of: (i) a theory exam with theoretical questions of the whole course (ii) solve a series of exercises similar to those worked on in the Classroom Practice sessions, and (iii) once finished, will have to answer some oral questions about concepts developed in the seminar sessions. These tests will take place on the same day, time and place as the tests of the second part of the continuous assessment modality. The student's grade will be the weighted average of the three previous activities, where the theory exam will account for 40% of the grade, the problem exam 40% and the oral questions 20%. If the final grade does not reach 5, the student has another opportunity to pass the subject through the recovery exam that in general will coincide with the date of the retake exam, or on a date set by the degree coordinator. In this test 70% of the grade corresponding to the theory and the problems can be compensated. The oral part is not redeemable."

S'hi troben molts continguts del curs, tot i així trobareu una exposició més moderna (i pel meu gust més clara) al Griffiths i Ballentine.
