# How to force a manual line break in author list in revtex4-1?

I am using revtex4-1, prl style. I have 6 authors. I want 4 authors in the first line of author list and 2 in the 2nd one. However, Latex is breaking the line after the 3rd author. I am using:

\documentclass[twocolumn,superscriptaddress,amsmath,amssymb,prl,aps,floatfix]{revtex4-1}

\usepackage{graphicx}
\usepackage{dcolumn}
\usepackage{bm}
\usepackage{multirow}
\usepackage{booktabs}
\usepackage{color}
\usepackage{longtable}
\usepackage{etoolbox}
\usepackage{url}
\usepackage{breakurl}
%\usepackage{authblk}

I have tried \mbox to lump together the first 4 authors and that doesn't work. I have tried \nolinebreak after the 3rd author and also it does not work either. I have also tried smaller font size to see if it helps but then it looks weird. Any ideas will be appreciated. Thanks!

• Welcome to TeX.SE! When you adding code try to select it and press {} button (else it is added as a text) – koleygr Aug 27 '17 at 3:25
• Welcome to TeX.SE! I can't seem to replicate exactly your problem (it's not breaking after the 3rd author), but try \author{\\john 5}? – Troy Aug 27 '17 at 3:33
• it doesn't break to me too... May be you have to extend your MWE by adding more code like changes in packages or definitions you made before reduce so much your code – koleygr Aug 27 '17 at 3:38
• Thanks all for the suggestions. I tried \author{\\John 5} and latex now breaks after the 4 author. Thanks again! – Camilo Aug 27 '17 at 3:55

A bit of a manual solution, but you can force line breaks in the author list of revtex4-1 by adding \\ before john5, in your case.

See the minimal example below.

\documentclass[twocolumn,superscriptaddress,amsmath,amssymb,prl,floatfix]{revtex4-1}
