Note that the definition of the fermionic operators is nonlocal with respect to the bosonic operators because we have deal with an entire chain of operators to the right of the site the fermionic operators are defined with respect to. This is also true the other way around. This is an example of a [['t Hooft operator]], which is a [[disorder operator]] instead of an [[order operator]]. This is also an example of an [[Sduality]].
