Math & Science ⇒ Alternatives for using the ">" and "<" Sign

[Tomahawk]

Hello,

I'm transcribing a lecture and the instructors notation for complex numbers is the following:

|0> for c=a +bi and <0| for c*=a-bi

when trying to typeset these in LaTeX there is an unwelcome spacing around the "<" and ">". How can I get rid of it? I didn't find any other way of expressing these signs in the comprehensive symbol list or any method of changing the spacing (although i would prefer not to do that, as i need those symbols otherwise with the spacing)

Code: Select all

\documentclass[a4paper,DIV12,12pt,headsepline]{scrartcl}
\usepackage[applemac]{inputenc}
\usepackage{lmodern}
\usepackage[ngerman]{babel}
\usepackage[intlimits, sumlimits]{mathtools}
\usepackage{amssymb}

\begin{document}
$|0> \cdot <0|$
\end{document}

You are probably searching for the commands \langle and \rangle. These are a kind of delimiter and they are scalable like braces, brackets and parentheses.

Code: Select all

\documentclass{scrartcl}
\usepackage[T1]{fontenc}

\begin{document}
  $|0\rangle \cdot \langle0|$
\end{document}
