Spinless Fermion correlator in Julia

Question

Hi!
I would like to know if there is any example code to measure spinless fermion correlator using the Julia version of ITensor?

Also I would like to know if using 'commonind(psi[i],psi[i-1])' in Julia the same as using 'leftLinkIndex(psi,i)' in C++ ?

Thank You

Hi, you should be able to follow essentially the same code as: http://www.itensor.org/docs.cgi?vers=cppv3&page=formulas/spinless_correlator_mps

Yes, you can use commonind(psi[i],psi[i-1]) or linkind(psi, i-1) to get the left link index of site i.
