How do I add additional author names and affiliations to my paper?
One way to add author affiliations is to use the authblk package. If you add
\usepackage{authblk}
to your preamble, you can then fill in the author and affiliation commands with the information you need. As an example, for a paper with two authors you could write:
\documentclass{article}
\usepackage{authblk}
\title{A random walk in \LaTeX}
\author[1]{Alison Carefully}
\author[2]{Ivor Question}
\affil[1]{Department of Mathematics, University X}
\affil[2]{Department of Biology, University Y}
\begin{document}
\maketitle
\section{In the beginning...}
There was something...
\section{In the end}
... there may be nothing.
\end{document}
This example produces the following output:
