Ironically, the paper itself was republished to fix figure placement [1]. To your main point, no, theoretical physics paper are almost all written in latex. I can't recall word-written theory paper. Experimental papers are sometimes word, but pretty rarely. You can try randomly sample papers from cond-mat arxiv to verify it.
