I am using the ReVTeX 4.1 template (for AIP journals), and while I was trying to add figures I noticed that the caption does not fill the whole column.

Is there a way to make caption fill the lines (and hence the column) as in the abstract or any other text in the body?

UPDATE:

I found out the problem: For some reason, loading the the subcaption package ruins the formatting of the figures captions in that they become unjustified & do not fill the whole line.

Example:

documentclass[aip,reprint]{revtex4-1}



draft 



usepackage{graphicx}

usepackage{epstopdf}

usepackage{gensymb}

usepackage{amsmath}

usepackage{subcaption}



captionsetup{labelsep = period}



usepackage{lipsum}



begin{document}



title{Draft}



author{LaTeX User}



date{today}



begin{abstract}

lipsum[1]

end{abstract}



maketitle 



 begin{figure}[h!]

    centering

    begin{subfigure}[b]{0.55textwidth}

        includegraphics[width=0.5linewidth]{example-image-a}

        caption{}vspace{0.3cm}

        label{fig:1a} 

    end{subfigure}

    begin{subfigure}[b]{0.55textwidth}

        includegraphics[width=0.5linewidth]{example-image-b}

        caption{}

        label{fig:1b}

    end{subfigure} 

    captionsetup{justification   = justified,

        singlelinecheck = false}    

    caption{lipsum[1]}  

    label{fig:1}

end{figure}



end{document}

For some unknown reason, the figure is formatted in onecolumn mode.

BTW, you probably shouldn't do this. Revtex4-1 uses unhbox for a reason (like deliberately undoing the caption package formatting).

This shows how to put the images and caption side-by-side. I converted the figure into a minipage and moved it inside the abstract. This is slightly more adaptable than an [H] figure using the float package.
