Hello all,
I have been trying to compute the expectation value of cdag(1) c(2) cdag(3) c(4) where two creation and two destruction operators are involved and 1, 2 ,3 and 4 label the sites in a spinless Hubbard model. Could anyone kindly tell me how I should define this in the parameter file or in the models.xml? Thanks a lot!
Best,
Jun
Hi Jun,
This is not currently implemented but depending on which code you use it can be added.

Hello, Matthias,
Thanks! I am using Exact Diagonalization to calculate some bond-bond correlation. Will ALPS 2.0 support it?
