Hello,
Is it possible to implement gauge fields for the lattice models? More explicitly, can one define:
- bond operators which are a function of the position of the source and target sites
- bond operators which are a function of the order in which the source and target sites are specified (say the source site is of type 1, and the target site is of type 2, then there should be a phase Exp[i phi], and conjugate if the source is of type 2 and target of type 1.)
Thanks for your answers, Alex
