Grader/TA: Alex Rasmussen

Office: 6218 Broida Hall
Office Hours: Thursday 1-4pm 


Textbooks: As for 215A, the "official" textbook for 215B is Sakurai/Napolitano (2nd edition).  There are many good QM books - including Shankar, Gottfried/Yan, Landau-Lifshitz, among others.  However, I am hoping to include some more modern topics (Landauer scattering theory, Quantum Ising model and Majorana Fermions) which are not in these books.  I will try to suggest other reading/books when relevant.

Homework:  Roughly 6-7 homeworks throughout the quarter, available on the course web site.  Homework solutions also posted online.  You are encouraged to work together on the homeworks.

Exams:  None.  Unless requested!

Help/feedback:  In addition to my office hours and Alex' office hours, I would be happy to schedule a mutually convenient time to chat about homework or other topics (best arranged by e-mail).  I would greatly appreciate feedback on any aspect of the course, anytime throughout the quarter.
