Especially in physics, there seems to have been a very clear dislike/distrust of results from people like Einstein on a political level, so if I am working under Heisenberg in 43 for example, can I get access to papers recently published by Jewish scientists in the US? Was there still a sense of an international scientific community? Could I go to the UK or Sweden to meet other researchers?
I'd love to know how much the war actually affected the daily lives of scientists and their ability to do their work.
Also was teaching impacted much? I know that Heisenberg was criticised for his work being too close to Einstein's and not working in the framework of "Deutsche Physik", but if I am a student with ambitions to join the "Uranprojekt" can I find a class on quantum theory at my local university, or do I have to seek out people like Heisenberg?
The Deutsche Physik movement that you reference re: Einstein/Heisenberg was not as powerful or influential as many people tend to think. You would still have had access to international journals prior to the onset of the war, and still would have been able to study what you wanted. The only person who was repeatedly harassed by the "movement" was Heisenberg, and even he wriggled out from under it and ultimately bested it. (No student is going to know about the Uranprojekt, so you aren't going to be ambitious about that, sorry. They either invite you in or nothing.) At practically any institution you are still going to be able to take courses in quantum theory. Anti-QM and anti-Einstein was never an official Nazi policy. By the time of the war the Deutsche Physik movement was essentially dead; Himmler supported Heisenberg against Stark/Lenard in 1938.
Once the war starts it's a bit different, as access to journals became more patchy in Europe in general (because of disruption of communication and shipping), and because the majority of the world's major physicists entered into war work and stopped publishing regularly. The odds are that if you are a young scientist in Germany at this time you are probably going to have your education disrupted by the war anyway — you'll be drafted or otherwise used for war purposes. Your professors themselves are likely to have been used for war purposes, as well.
If you were a more senior scientist, there would potentially be opportunities for traveling abroad to neutral or occupied countries. I don't know how "minor" you could be and still get to do this, but many German scientists (Heisenberg included, but also lesser scientists) did go to Denmark, France, Italy, and other occupied/allied places of science to exchange work, learn about what they were doing, and be "cultural ambassadors" (show them that the Germans weren't "all bad" and still respected science; Heisenberg did a lot of this). You would definitely not be allowed to go to the UK or any country that Germany was actively at war with.
The best book on the Deutsche Physik movement is Mark Walker's Nazi Science. It also discusses a lot about the Uranprojekt as well.
