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 as the only other pack­age avail­able was sim­plewick, which is rather un­wieldy.

This pack­age pro­vides a sim­pler syn­tax for Wick con­trac­tions.
