I am in the process of applying right now to many physics graduate programs. The deadlines seem to be stacked on 12/1 and around 12/15 for the top programs. I doubt there is a list of deadlines that someone compiled and put on 1 page... people applying to physics grad programs can definitely scout out the deadlines on their own ;)
I think the deadlines are specific to the graduate school itself and not the department. Thus it would be more useful to ask for a list of deadlines by university. There probably isn't a list, though, since it takes about a minute to google a deadline.
