This document gives a brief summary of what's new in \revtex~4.1. The changes include bug fixes, improved functionality, and support for a wider range of journals, including those of the American Institute of Physics (AIP). \revtex~4.1 was developed jointly by APS, AIP, and Arthur Ogawa. Additional work was done by Patrick Daly to incorporate our suggested improvements into \texttt{natbib 8.3} to address many new features concerning bibliographies. \texttt{natbib 8.31a} or later is required to run \revtex~4.1.

\section{New Syntax and Features in \revtex~4.1}

\revtex~4.1 introduces support for more journals, several new commands, and some new syntax. This section outlines these changes. \textbf{A document using these new features will not process under \revtex~4}. See Sec.~\ref{sec:additional} for more details about these items.

\begin{itemize}

\item \textbf{Added support for APS journal \textit{Physical Review Special Topics -- Physics Education Research}}.

\item \textbf{Added support for AIP journals.} There is now an explicit \texttt{aip} society option along with support for AIP journals. Please see the \textit{Author's Guide to AIP Substyles for \revtex~4.1}. In addition, \revtex~4.1 provides an extensible system for the easy addition of new collections of journals.

\item \textbf{Endnotes now ordered correctly.} Endnotes in the bibliography now appear in the correct order, interleaved with citations.

\item \textbf{Multiple references in a single citation supported using a special starred (*) argument to the \cmd\cite\ command.} One of the major new features in 4.1 made possible by the joint work on \texttt{natbib 8.3}. Multiple Bib\TeX\ entries can be combined into a single \cmd\bibitem\ command.

\item \textbf{Bib\TeX\ style files can now display journal article titles in the bibliography.} Use the \texttt{longbibliography} class option.

\item \textbf{Free form text can be prepended and appended to a bibliographic entry using the special starred (*) argument to the \cmd\cite\ command.} Often a citation in the bibliography will have explanatory text such as \textit{See also} or \textit{and references therein} before and after the actual citation. The new \revtex~4.1 \cmd\cite\ command allows the specification of both text to precede and follow a citation.

\item \textbf{Structured Abstracts.} Use of the \texttt{description} environment in abstracts now provides for ``structured" abstracts.

\item \textbf{Figures referring to videos now supported.} A ``figure" may now be labeled as a \textbf{Video} by using the \texttt{video} environment. A frame from the video may be included in the figure and a URL to link the caption's label to the online video also may be included. There is also a \cmd\listofvideos\ command.

\item \textbf{Better support for arXiv.org in Bib\TeX\ } Three more Bib\TeX\ fields have been added: \texttt{SLACcitation}, \texttt{archivePrefix}, and \texttt{primaryClass} in addition to the existing field \texttt{eprint}.

\end{itemize}

\section{Bug Fixes in \revtex~4.1}

One of the main goals of \revtex~4.1 is, of course, to fix the bugs that were released in \revtex~4. The following is a list of bugs that have been fixed.

\begin{itemize}

\item \textbf{Improved Bib\TeX\ \texttt{bst} files.} In addition to the new features above, numerous other improvements to the APS \texttt{bst} files have been made, including support for displaying journal article titles and many fixes for \textit{Reviews of Modern Physics}. Also, long author lists are no longer automatically truncated.

\item \textbf{\cmd\footnote\ in \cmd\widetext\ and \texttt{table*} environments improved.} \cmd\footnote\relax s in the \cmd\widetext\ or \texttt{table*} environments are now correctly placed and formatted.

\item \textbf{Email addresses no longer print twice on papers less than one page long.}

\item \textbf{\texttt{eqnarray} alignment improved.}

\item \textbf{\cmd\collaboration\ can be used with the \texttt{groupedaddress} option now.}

\item \textbf{\texttt{letterpaper} now ensured as default paper size.}

\item \textbf{Table of Contents formatting improved.}

\item \textbf{Support for \texttt{longtable} and \texttt{lscape} packages improved.}

\item \textbf{\texttt{reftest} restored.}

\item \textbf{Compatibility with the \texttt{geometry, lineno,} and \texttt{colortbl} packages improved.} For line numbering, rather than using \texttt{lineno.sty} directly, the \texttt{linenumbers} class option should be used (this will call in \texttt{lineno.sty} with a proper set of default parameters).

\item \texttt{hyperref} \textbf{fixes}. Improved compatibility between footnotes and the \texttt{hyperref} package. In particular, table footnotes were fixed. More anchors for \texttt{hyperref} were also added (titlepage, abstract, and acknowledgements).

\item \textbf{Documents can have more than 256 \cmd\cite\ commands now.}

\item \textbf{\cmd\listoffigures\ and \cmd\listoftables\ fixed.}

\item \textbf{Figure and table labels in captions now reflect proper APS style.}

\item \textbf{RMP style files conform better to RMP style guidelines.}

\item \textbf{Section heading upper-casing improved.}

\item \textbf{Repeated characters at start of affiliation no longer disappear when using \texttt{groupedaddress} option.}

\item \textbf{There have been many other bug fixes and improvements to the internal \texttt{ltxgrid} package as well.}

\end{itemize}

\section{\revtex~4 Backwards Compatibility}

The vast majority of documents prepared under \revtex~4 should process correctly under \revtex~4.1. However, the formatting of the pages and, if using Bib\TeX, the references may change. Also, the behavior of some macros may be different. For instance, the \texttt{title} macro now requires the use of \texttt{protect} for fragile arguments. This may cause some documents prepared under \revtex~4 to fail under 4.1. Some macro packages that depend on the internals of \revtex~4 may also no longer work. Documents using those packages will, of course, also will not process under 4.1.

\section{\label{sec:additional}Additional Details}

\subsection{Multiple references in a single bibliography entry}

One of the most frequently requested features since the release of \revtex~4 has been to allow more than one reference to appear in a single bibliography entry when using Bib\TeX. This can now be done in \revtex~4.1 by using a starred (*) argument to the \cmd\cite\ command. This requires the latest version of \texttt{natbib}, developed in conjunction with \revtex~4.1, and the new \texttt{bst} files that come with \revtex~4.1. To combine multiple references into a single \cmd\bibitem, precede the second, third, etc. citation keys in the \cmd\cite\ command with an asterisk (*). For example \verb+\cite{bethe, *feynman, *bohr}+ will combine the \cmd\bibitem\relax s with keys \texttt{bethe}, \texttt{feynman}, and \texttt{bohr} into a single entry in the bibliography separated by semicolons.

\subsection{Prepending and/or appending text to a citation}

The expanded syntax for the \cmd\cite\ command argument can also be used to specify text before and/or after a citation. For instance, a citation such as:

\begin{verbatim}

100

[19] A similar expression was derived in

101

A. V. Andreev, Phys. Rev. Lett. 99, 247204

102

(2007) in the context of carbon nanotube

103

p-n junctions. The only difference is that no

104

integration over ky is present there.

105

\end{verbatim}

106

may be created by the following \cmd\cite\ command:

107

\begin{verbatim}

108

\cite{*[{A similar expression was derived

109

in }] [{ in the context of carbon nanotube

110

p-n junctions. The only difference is that no

111

integration over ky is present there.}]andreev2007]

112

\end{verbatim}

113

Please note the use of curly braces to enclose the text within the square brackets.

114

\subsection{Structured Abstracts}

115

A ``structured" abstract is an abstract divided into labeled sections. For instance, \textit{Physical Review C} would like authors to provide abstracts with sections summarizing the paper's \textbf{Background}, \textbf{Purpose}, \textbf{Method}, \textbf{Results}, and \textbf{Conclusions}. This can be accomplished by using the \texttt{description} environment within the \texttt{abstract} environment. For example:

116

\begin{verbatim}

117

\begin{abstract}

118

\begin{description}

119

\item[Background] This part would describe the

120

context needed to understand what the paper

121

is about.

122

\item[Purpose] This part would state the purpose

123

of the present paper.

124

\item[Method] This part describe the methods

125

used in the paper.

126

\item[Results] This part would summarize the

127

results.

128

\item[Conclusions] This part would state the

129

conclusions of the paper.

130

\end{description}

131

\end{abstract}

132

\end{verbatim}

133

134

\subsection{Video Environment}

135

Papers often refer to multimedia videos. The \texttt{video} environment is identical to the \texttt{figure} environment, but the caption will be labeled as a \textbf{Video} (with its own counter independent of figures). A URL can also be specified so that the caption label can be linked to the online video (if using the \texttt{hyperref} package). The included graphic (using \cmd\includegraphics\ from the \texttt{graphics} or \texttt{graphicx} package) would be a representation frame from the video. A \texttt{\cmd\listofvideos} is also provided. For example:

136

\begin{verbatim}

137

\begin{video}

138

\includegraphics{videoframe.jpg}

139

\setfloatlink{http://some.video.com/fun.mov}

140

\caption{\label{vid:interest}This is a video of

141

something fun.}

142

\end{video}

143

\end{verbatim}

144

145

\subsection{Better arXiv.org support in Bib\TeX\ }

146

147

148

There have been substantial improvements in the \revtex\ Bib\TeX\ style files. For instance, the \texttt{.bib} entry

149

\begin{verbatim}

150

@Unpublished{Ginsparg:1988ui,

151

author = "Ginsparg, Paul H.",

152

title = "{APPLIED CONFORMAL FIELD THEORY}",

153

year = "1988",

154

eprint = "hep-th/9108028",

155

archivePrefix = "arXiv",

156

SLACcitation = "%%CITATION = HEP-TH/9108028;%%"

157

}

158

\end{verbatim}

159

will include the arXiv.org e-print identifier as \texttt{arXiv:hep-th/9108028} and hyperlink it (if using \texttt{hyperref}). The newer format for arXiv identifiers with primary classificiations will produce output such as \texttt{arXiv:0905.1949 [hep-ph]}.
