RevTeX has chosen to use the \varepsilon symbol for both the \epsilon and the \varepsilon: http://www.physics.udel.edu/~bnikolic/teaching/phys660/PDF/revtex4.pdf (p. 25).

Is there a way to re-introduce the normal \epsilon?

  • What you call the ‘normal’ epsilon is the lunate epsilon, which looks ,like the $\in$ symbol. The normal epsilon, for any linguist, is precisely ε. – Bernard Jun 18 at 13:58

The issue has nothing to do with the revtex4 class, and


yields the expected result: enter image description here

The manual has been typed with a Times font; my guess is mathptmx. If you look at the corresponding font table

% \usepackage{mathptmx}
% contains the following declaration:
% \DeclareSymbolFont{symbols}{OMS}{ztmcm}{m}{n}


enter image description here

you see that \epsilon (slot 15) and \varepsilon (slot 34) look in fact the same. Ditto for \rho and \varrho.

Unrelated: revtex4 is almost 20 years old, and is listed in CTAN under "obsolete". revtex4-2 came out last year. For new papers, it might be a good idea to switch :-)
