Creation and Annihilation Operators
... Operators for fermions can be written in a similar way, using f in place of b, again with creation operators on the left and annihilation operators on the right. In the case of two-body (and three-body, etc.) operators there can be a sign ambiguity because fl fm = −fm fl , so pay attention. ⋆ Exerci ...
