Fall 2021: PHYS 502  Condensed Matter Physics I
The full information regarding this course will be available on its Canvas page. Below is a summary you might find useful before the access to the Canvas page becomes available in early Sept. Lectures:
Prerequisites:: An undergraduatelevel course in solid state physics, such as PHYS474. Grading scheme: TBD Syllabus: The goal of this course is to provide a graduatelevel introduction to some of the fundamental concepts of condensed matter physics. The main goals are to become fluent in second quantization language; to be familiar with assumptions behind various models and when are they justified; to be able to calculate bandstructures for noninteracting electronic systems and to determine if that material is a metal or an insulator; to carry out HartreeFock and Random Phase Approximations for interacting electronic systems; to find the phonon spectra of various materials; to be able to characterize some of the effects of electronphonon coupling both on the electrons and on the phonons; and to become familiar wiht the basics of the Boltzmann transport theory, the BCS theory, and how to calculate the magnon dispersion in simple magnetic systems. It is assumed that you are familiar with the basic concepts of solid state physics (e.g. crystalline lattices, Bloch bands, Drude model etc.) as covered in a typical undergraduate solid state course such as UBC's PHYS 474. In addition, working knowledge of quantum mechanics, basic statistical physics and thermodynamics will be assumed. Recommended books: I will provide typed notes for all the material we will discuss in this course. I have used several books, listed below, as inspiration for these notes. The project: Your project will be a roughly 4 pages long report on a topic related to the material studied in this course. Ideally you should work on something of direct interest for your M.Sc./Ph.D. research. If you are an experimentalist, you might decide to describe your experiment or maybe focus on the theoretical framework used to explain what is being measured. Theorists are more likely to discuss additional theoretical methods, or expand on those discussed in class, or solve specific problems, but you are free to report on any aspects of experimental physics, if you wish. At the beginning of October I will make sure that each of you has a reasonably ambitious project. When you're making your choice, make sure that either you have a topic not covered in previous years, or that it focuses on different aspects than those covered before. Have a look at the previous projects also in order to get a feeling for the level of detail expected. The typed reports should be submitted to me by the end of the term (exact date TBD). Then, we will mimic the process of submission for publication. I will randomly pick three anonymous referees for each project (thus, each of you will have to review three reports). You will then get a chance to respond to your referee reports and address the issues raised. The referees will then give your report a grade, which will be weighted towards your project grade. We will discuss this more as we go along, but the project grade will be based not just on the project itself, but also on your participation to the refereeing process both as an "author" and as a "referee". Homework: There will be 5 biweekly sets. Set 0 is a "test assignment" and will not be graded. If you can solve it without too much trouble then you are ready for this course. If not, then you should take PHYS 474 first. All other sets will be
graded, however the lowest grade of the 5 will not count
towards your final grade. The problem sets will be posted, uploaded and graded through the Canvas page. To encourage you to meet and know your colleagues, one problem in each set will have a group solution, meaning that each group submits a single common solution and all students in the group receive the same mark for that problem. The remaining problems should be solved and submitted individually, and will be marked as such. I will select different groupings for the 5 assignments so that you get to meet and work with as many other students as possible.
Both the group and the individual solutions
should be neatly written, with problems in the order assigned. Use a scanning app such as Genius Scan to make to produce a good quality pdf file, which should be uploaded through the Canvas PHYS502 website before the deadline (end of the lecture on due date). The solutions will be
posted online immediately after the class; as a result, late homeworks will not be
accepted.
Exams: We will discuss the details at the appropriate time.
