I'm only at the end of the second year (out of 5) of a physics bachelor. I plan on to do a Phd although I've absolutely no idea in which area (and I know the admission will be very hard). After the Phd I'd like to do research for the rest of my life. Is that possible in the US? For example in France there is the CNRS (national center of scientific research) and once you get in (extremely hard), you have very few obligations to accomplish. By this I mean that one does not have to publish every year or so. Alain Connes said that a mathematician can work his whole life on a single problem, contrarily as in the US where, according to him, one has a lot more pressure to publish, resulting in papers of lesser quality. (I'm not criticizing the US system, I just repeat what I've read in an interview of Alain Connes). In Argentina there exist the CONICET which seems very similar to the French CNRS. Most my current professors work at the CONICET and I believe they're all experimentalists. Once one has entered the CONICET, there's not a big pressure to publish. You could think that it's not good because a researcher could get lazy, but I think they're serious and publish regularly. (According to what I've seen at my University). I'm curious if there exist similar institutions/centers in the US (or Canada or any other country) that allow you to study in most branches of physics (including theoretical physics) and where you could publish once in 2 or 3 years or even more if you're working on a long project. Thanks for your time.
