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