This is really a very strange question :D. I am trying to find the LaTeX template for the Journal of Mathematical Physics. I found this on sharelatex.com and I downloaded the RevTex4-1 file from aip.scitation.org/jmp/authors/manuscript. But if I compare the pdf files from sharelatex.com and from the samples folder they seem to be different to papers published in the Journal of Mathematical Physics (e.g. "Exactly solvable Hermite, Laguerre, and Jacobi type quantum parametric oscillators").
I hope someone can help me out :).
