Which Universities admit CS graduates for their theoretical physics course? Hello am currently an undergraduate student. My major is CSE. But I am very much interested to do my masters and then PhD in theoretical physics/mathematical physics. Is there any university that admits CS graduates for these courses?
I have looked up some universities that offer these courses.
Queen Mary University, University of Edinburgh and Durham University sounds perfect to me (I can meet their minimum requirements).
But I am not sure whether they admit CS graduates or not. I have not got any reply from them yet. 
Would you suggest some Universities both in the UK and US that do? Would any university admit me directly for PhD (without masters)? Will having research paper help?
I could not find any university in the US that offer this course for masters.
I can't speak for the UK, which has a different educational system altogether, but in the US, most programs would find a CS graduate "acceptable" for a physics doctorate. This assumes a good record overall, of course, and probably a few physics courses in which you did well. In the US, a CS student probably has a few such courses, though not advanced ones. 

But to actually be admitted you have to be better than "acceptable". 

In the US, the graduate program has quite a few courses available, primarily to prepare the student for comprehensive exams. But the normal path would be into a doctoral program, perhaps with an MS along the way. 

I would guess that in the UK the university would expect an applicant to be further along in the major subject, but others would need to verify.
