FYSS7531 Quantum Mechanics II A, spring 2020
Lecturer: Tuomas Lappi, office FL240
Teaching assistant: Henri Hänninen, office FL353
Course materials, exercise returns, solution suggestions etc are in
The classes for QMIIA will meet on Tuesday from 12 to 16 and on Thursday from 12 to 14 in FYS2.
Exception: first day of class on Wednesday Jan 8th from 10 to 14, with lunch break in between.
The division of these between
lectures and exercises will not follow the labeling in korppi. The weekly schedule will proceed in the following way:
Before Tueday's class you must read the given reading assignments for
each week. With the help of these you should solve some simple preliminary
exercise problems and be prepared to discuss your solutions in
class on Tuesday.
On Tuesday we will discuss the preliminary problems and the reading assigments, first in smaller groups and then together, on the blackboard. The lecturer can also discuss on the blackboard any other questions you have on the reading assignment material.
After the Tuesday class you should start working on the main homework
- The class on Thursday will be a tutorial session for working on these problems together.
- The solutions must be returned in moodle, as a (scanned handwritten) pdf document, by Friday 21h.
- After the solution return deadline you will get access, in moodle, to suggested solutions (hand written by the lecturer, please ask if the writing is unintelligible). With the help of these solutions must now grade your own solutions on a scale of 0 to 3 points per problem. At this stage you can (using a different color pen) correct and complement your solutions.
- Your self-graded problem answers must then be returned again in moodle, by Monday at 14. The TA will check that you have been honest in your grading, record the exercise points, and give extra points if you have successfully corrected or complemented your solutions. Just copying the model solution does not give any extra credit.
NB: every week there are two sets of exercise problems:
- The preliminary exercises which you should do while reading the assignment,
these will be discussed in groups in class on Tuesday.
- The written
exercises, for which you hand in your solutions in writing by Friday
night and again your self-graded solutions by Monday.
The course does not follow a single set of lecture notes. Instead, at this
stage you should get used to following a variety of different sources.
Every student is expected to acquire access to at least two of
the following sources
- Lecture notes of Kimmo Tuominen from Helsinki, available in moodle. Except for the first week the course will mostly follow the content and ordering in these notes.
- "Modern Quantum Mechanics" by J.J. Sakurai (older edition, you might try looking for this online), newer edition by J.J. Sakurai and J. Napolitano (available in FYS4). This is the secondary reference followed by the lecturer, but the course will not follow the order in the book.
The older edition is fine for the A-part of the course, but lacks
a discussion of the quantized electromagnetic field that will be needed in part B, this has been
added in the new edition.
- Lecture notes of Tero Heikkilä from the 2017 course, available
- Lecture notes of Kari J. Eskola, URL and password visible in moodle.
- Kvanttimekaniikka II by J. Niskanen (in Finnish, available in FYS4, for sale at LIMES)
- Quantum Mechanics, by Bransden and Joachain (available in FYS4). This book is very extensive, i.e. covers a lot of material, especially what is needed in this part A.
The preliminary exercises contribute 20%, the written exercises 40% and
the exam 40%. If you cannot make it to class on Tuesday and want to get
credit for the preliminary exercises, you can return your solutions in
writing (paper or scanned pdf) to the lecturer by Tuesday at 12h. The exam will be an oral exam, date to be agreed later. If you request, we may also choose to take a written exam instead, but this must be agreed with the lecturer separately.
