The aim of the course is to give a thorough review of the various applications of quantum mechanics, as introduced in the first part (PHYS220), and to further develop those and new techniques. To that end, an application of symmetry is further developed, quantum fields statistical mechanics introduced and related to their classical counterparts. In addition, we study concrete applications to (1) Nuclei, (2) Periodic (crystalline) systems, (3) Atomic spectra, (4) Interatomic (chemical) forces, (5) Subnuclear and “fundamental” physics.

Note: in case of classcancellation (such as due to inclement weather), a soon Friday 2:103:30 pm time will be used to makeup the class 
All homework assignments are due by 5:00 pm of the day indicated and should be either given to the instructor in hand, left in the instructor's mailbox in TKH#105, or slid under the instructor's office door, TKH#213. Late homework will not be accepted, except in cases of proven (medical) emergency.
Collaboration policy Collaboration  but not blind copying  on the homework assignments is strongly encouraged; students should use this to learn from each other. All exams and quizzes are open text and open classnotes (including notebooks and class handouts), but no collaboration is allowed; by signing the exams and quizzes, the student implicitly agrees to abide by this policy. Violation of this policy is covered under University regulations on academic dishonesty and cheating.
Presentation and organization While a neat presentation of home, quiz and examwork is not required for full credit, it certainly makes it easier to assess the quality of the work and give the proper credit due. In all cases, include a simple sketch if it might help conveying the approach or the calculations. Where necessary, include all units and symbols such as the measure of an integral, arrow on a vector, vertical bars for the absolute value of a quantity, for the magnitude of a vector or for the determinant of a matrix, etc.
