$\mathrm{\TeX}$ and $\mathrm{\LaTeX}$

$\mathrm{\TeX}$ is one of the masterpieces of Don Knuth.

It is the uppercase version of $\tau\epsilon\chi$, a Greek word for Tech, which is how $\mathrm{\TeX}$ should be pronounced (!?).

At some point in the early 2000, I switched to $\mathrm{\LaTeX}$ for convenience, and almost exclusively use the latter now.

Equations

Alignment

Splitting equations within an aligned set can be done as followed~[1]:

\begin{align}
  a &= \begin{aligned}[t]
      &b + c + d +\\
      &c + e + f + g + h + i
       \end{aligned}\\
  k &= \begin{aligned}[t]
      &l + m + n\\
      &+ o + p + q
       \end{aligned}
\end{align}

\begin{align} a &= \begin{aligned}[t] &b + c + d +\\ &c + e + f + g + h + i \end{aligned}\\ k &= \begin{aligned}[t] &l + m + n\\ &+ o + p + q \end{aligned} \end{align}

To align equations as if in a table (?!), one can use [2] This is to integrate $\int x\sin(k\pi x)dx$ by parts.

\begin{align}
  u&=x  & v&=-\frac{1}{k\pi}\cos(k\pi x)\\
  u'&=1 & v'&=\sin(k\pi x)
\end{align}

\begin{align} u&=x & v&=-\frac{1}{k\pi}\cos(k\pi x)\\ u'&=1 & v'&=\sin(k\pi x) \end{align}

International accents

We try to write your name properly when we quote it. Here are the most common glyphs and the code needed to do so:

$?`$Does this work?

Fonts

See Will Robertson preambles to use different fontsets.

Formatting

Wrapping figures in text: [3]

Lists

To change spacing between items, put after \begin{itemize}:

\addtolength{\itemsep}{-0.5\baselineskip}

To change the starting value of an enumerate list:

\begin{enumerate} \setcounter{enumi}{4} \item fifth element \end{enumerate}

To change enumeration (with square brackets, parentheses, etc.): (see [4])

\usepackage{enumitem}% http://ctan.org/pkg/enumitem \begin{document} \begin{enumerate}[label={[\arabic*]}] \item First item \item Second item \item \ldots \item Last item \end{enumerate} \end{document}

Footnotes

There is a $\mathrm{\LaTeX}$ package, footmisc, that is useful for manipulating footnote formatting.

Spacing between footnotes:

%\footnotesep is the space between footnotes: \setlength{\footnotesep}{-0.5\baselineskip}

%\footins is the space between the text body and the footnotes: \setlength{\skip\footins}{1cm}

To use footnotes to feature reference-style annotations, that is, with no subscripts and with enclosing brackets [1], add in the preamble:

\makeatletter \renewcommand{\@makefnmark} %{\@textsuperscript{\textit{\tiny{\@thefnmark}}}} {[\@thefnmark]} \renewcommand\@makefntext[1]{%


   \parindent 1em
   \noindent
   [\@thefnmark]\enspace #1}

\makeatother

(I left, commented, the original definition of the footnote).

Geometry

\usepackage[a4paper, total={6in, 8in}]{geometry}

see [5] or [6].

Units

We use the siunitx package:

\usepackage{siunitx}

It'd take \SI{500}{\milli\second} to understand.

Please write \SI{10}{\micro\meter} and not 10$\mu\mathrm{m}$

There is also a SIUnits which is however deprecated [7]. Sometimes it comes in handy, for instance when you want to add non-numerical inputs (though siunitx should be able to allow that as well).

To write inverse unit, use \per:

shows the PL emission of a \SI{3}{\micro\meter} wire, where one can
observe the splitting between the two first confined subbands, the
polarization splitting, and the crossing of the X and Y (labelled TE
and TM here) polarized lines around \SI{2.6}{\per\micro\meter},
whereas the value given by the formula above is
\SI{2.1}{\per\micro\meter}.

The powers of ten can be counter-$\mathrm{\LaTeX}$-intuitive:

with a density of $\SI{e-3}{\per\square\micro\meter}$

If you do not use SI units, then omit the slash:

repetition rate of SI{3}{gb/s}

(that would be giga-bits per seconds).

Line numbering

It's useful to number profusely manuscripts of which you are discussing every line. Package lineno does that.

\usepackage{lineno}
\linenumbers

It may have a hard time cohabiting with amsmath, however. It appears that if you include this monstrosity somewhere in your preamble, it'll perform well enough for line-dropping with your co-authors:

\newcommand*\patchAmsMathEnvironmentForLineno[1]{%
  \expandafter\let\csname old#1\expandafter\endcsname\csname #1\endcsname
  \expandafter\let\csname oldend#1\expandafter\endcsname\csname end#1\endcsname
  \renewenvironment{#1}%
     {\linenomath\csname old#1\endcsname}%
     {\csname oldend#1\endcsname\endlinenomath}}% 
\newcommand*\patchBothAmsMathEnvironmentsForLineno[1]{%
  \patchAmsMathEnvironmentForLineno{#1}%
  \patchAmsMathEnvironmentForLineno{#1*}}%
\AtBeginDocument{%
\patchBothAmsMathEnvironmentsForLineno{equation}%
\patchBothAmsMathEnvironmentsForLineno{align}%
\patchBothAmsMathEnvironmentsForLineno{flalign}%
\patchBothAmsMathEnvironmentsForLineno{alignat}%
\patchBothAmsMathEnvironmentsForLineno{gather}%
\patchBothAmsMathEnvironmentsForLineno{multline}%
}

Compilation

Use texfot to get rid of the flood of output generated by compilation and retain only the warnings:

texfot pdflatex Microcavities.tex
