Fully justify caption in RevTex 4-2

captionshorizontal alignmentrevtex

I'm writing a paper with REVTeX 4.2 using Overleaf and want the captions of my figures to be fully justified, but they are automatically centering. I've read this question about the same problem in RevTex 4.1, but I'm wondering if there's a way to full justify my captions with the regular figure and table environments without using \subfloat. The figure and table environments are automatically numbered, so I won't need to renumber everything if I want to add a figure to the beginning of the document.

I've also tried \usepackage{caption} with \captionsetup{justification=justified, singlelinecheck=false}, but that didn't work.

The header and an example figure for my document are below:

\documentclass[reprint,amsmath,amssymb,aps,floatfix]{revtex4-2}

\usepackage[margin=1.5cm]{geometry}
\usepackage{tabularray}
\usepackage{caption}
\captionsetup{justification=justified, singlelinecheck=false}
\usepackage{graphicx}
\usepackage[tiny, center, uppercase]{titlesec}

\titlespacing\section{0pt}{12pt plus 0pt minus 0pt}{3pt plus 0pt minus 0pt}
\titlespacing\subsection{0pt}{12pt plus 4pt minus 2pt}{0pt plus 2pt minus 2pt}
\titlespacing\subsubsection{0pt}{12pt plus 4pt minus 2pt}{0pt plus 2pt minus 2pt}

\begin{document}

...
...

\begin{figure}[t!]
    \includegraphics[width=.5\textwidth]{experimental_diagram.jpg}
    \caption{Experimental setup. This diagram shows...}
    \label{fig:experiment_setup}
\end{figure}

\end{document}

You can't use caption package but you could disable the centre-single line check in other ways.

\documentclass[reprint,amsmath,amssymb,aps,floatfix]{revtex4-2}

\usepackage[margin=1.5cm]{geometry}
\usepackage{tabularray}

\usepackage{graphicx}
\usepackage[tiny, center, uppercase]{titlesec}

\titlespacing\section{0pt}{12pt plus 0pt minus 0pt}{3pt plus 0pt minus 0pt}
\titlespacing\subsection{0pt}{12pt plus 4pt minus 2pt}{0pt plus 2pt minus 2pt}
\titlespacing\subsubsection{0pt}{12pt plus 4pt minus 2pt}{0pt plus 2pt minus 2pt}

\begin{document}

...
...

\begin{figure}[t!]
    \includegraphics[width=\columnwidth]{example-image}
    \makeatletter\long\def\@ifdim#1#2#3{#2}\makeatother
    \caption{Experimental setup. This diagram shows... }
    \label{fig:experiment_setup}
\end{figure}

\end{document}

The caption package is not compatible with revtex4-1; you can still add captioned subfloats with

\usepackage[caption=false]{subfig}

in the preamble and a syntax such as

\subfloat[]{\label{fig:FIG11}%
  \includegraphics[width=0.24\textwidth]{FIG11.eps}%
}

In the optional argument of \subfloat you can supply also a subcaption; if empty, only the markers (a) (b) and so on will appear.

Indeed the behavior you've described is the default in revtex4-1.

This isn't "in effect", as you said, just because you're loading the caption package, which is incompatible with that class.

So, don't load either caption nor subcaption and you will have your captions in a \small font and justified.

MWE

\documentclass[reprint,aps,prl,twocolumn ,groupedaddress,nobibnotes]{revtex4-1}
\usepackage[demo]{graphicx}

\begin{document}
\begin{figure}
\includegraphics[width=.9\linewidth]{circuits.png}
\caption{This is a long sentence to test whether the caption is justified
 or not. Unfortunately it is not.}
\end{figure}
\end{document}

EDIT (in response to the OP's comment)

minipages are not incompatible with revtex4-1.

Here's an example of how to have two images side by side, in one column and in two columns mode.

\documentclass[reprint,aps,prl,twocolumn ,groupedaddress,nobibnotes]{revtex4-1}
\usepackage[demo]{graphicx}

\usepackage{lipsum}

\begin{document}

\begin{figure}
\begin{minipage}[t]{0.48\linewidth}
\includegraphics[width=.9\linewidth]{circuits.png}
\caption{This is a long sentence to test whether the caption is justified
 or not. Unfortunately it is not.}
\end{minipage}\hfill%
\begin{minipage}[t]{0.48\linewidth}
\includegraphics[width=.9\linewidth]{circuits.png}
\caption{Another figure.}
\end{minipage}%
\end{figure}

\begin{figure*}
\begin{minipage}[t]{0.48\linewidth}
\includegraphics[width=.9\linewidth]{circuits.png}
\caption{This is a long sentence to test whether the caption is justified
 or not. Unfortunately it is not.}
\end{minipage}\hfill%
\begin{minipage}[t]{0.48\linewidth}
\includegraphics[width=.9\linewidth]{circuits.png}
\caption{Another figure.}
\end{minipage}%
\end{figure*}
\end{document}

Output (two images in the same column)
