I would like to give a unique label to each author and affiliation in revtex, so to use them as I wish without repetitions.

The article class offers the \affil command within the authblk package:


\title{Article Title}

\author[1,2]{D. Duck}
\author[2,3]{M. Mouse}
\author[1,4]{H. Simpson}



This is an article.

But when switching to revtex I get this error:

! LaTeX Error: Command \c@affil already defined.

Many thanks

\title{Article Title}
  • The compilation goes through but there's no title in the output. In the log file: Class revtex4 Warning: No title. May 13, 2019 at 7:27
  • 1
    I see. I suppose that class revtex4 and package authblk are incompatible, because rectex4 has a lot of commands for affiliations and so on.
