PHY2406F

Third homework assignment

N.B.: I will be away lecturing at the VI Mexican School on Quantum Gravity during 21-25 November. I canNOT promise decent e-mail access while away, so please start HW#3 now and take full advantage of my office hours next week on 19th November! I will be back just in time to lecture - and collect your HW#3 assignments - on the 26th.

Note: People did really well with the previous two homework assignments - congratulations! To measure "better" overall, I therefore need to make this problem set harder/longer. I expect that some students may not have time to finish this bigger assignment; if this occurs for you, then please do the problems of most interest to you and remember that everyone is in the same boat.

Zwiebach problem Subject
Z14.3, Z14.4Orientifolds with D-branes
Z15.7 The H[3] field and the circular closed string; Read sections 15.1-15.4 first!
Z16.5; Z16.9Open superstring Hagedorn temperature; Estimating the size of a string state.
Z17.4Compactification on T2 with a constant Kalb-Ramond field
Z20.6,20.7String ending on a D-brane in Born-Infeld theory, parts I and II; Read sections 20.2-20.3 first!

Note

My office hour exists for explaining stringy physics; please feel free to make good use of it. I also encourage students to discuss the general physics behind these questions together, e.g. in a study group. (Your answers must, however, be individual, in accord with principles of academic integrity.)
