simpler-wick – Simpler Wick contractions

In every quantum field theory course, there will be a chapter about Wick’s theorem and how it can be used to convert a very large product of many creation and annihilation operators into something more tractable and normal ordered.

The contractions are denoted with a square bracket over the operators which are being contracted, which used to be rather annoying to typeset in LaTeX as the only other package available was simplewick, which is rather unwieldy.

This package provides a simpler syntax for Wick contractions.
