I'm a Junior-year physics major and I've just gotten an invitation to do some theoretical research with a couple of the professors at my school, which I'm really excited about. They're looking at Bose-Einstein condensation of molecules with electric dipole interactions, so although I get the gist of it and I'm sure I'll be able to handle my small part, a lot of it is over my head. I would like to learn as much about the subject as possible to get a better sense of the project as a whole. Obviously my professors will be the best resource, but they'll only have so much time to meet with me and I always like to have something to stare at and work through at home. But every text I've found online about many-body problems is intended for third or fourth year graduate students. I know it's not really a subject intended for undergrads, but I was hoping to find some kind of resource that could be tackled at something like an early graduate / advanced undergrad level. Maybe there's nothing like that floating around, but I thought I'd ask just to see. Does anyone know of any resources that would fit the bill?
