Many body correlator

  1. Jan 20, 2015 #1
    Hi all, I am trying to calculate the correlator between two different creation and annihilation operators on a many body system. The system is composed by two wires (left and right) and an energy level between them $\epsilon_{0}$. So we have the creation and annihilation operators on the wires, $c_{L,R}^{\dagger},c_{L,R}$, and the ones with the dot level $d^{\dagger}, d$. Then, how could I find out the correlator (equal time correlation):

    \langle c_{L}^{\dagger}(x)d\rangle

    Any ideas?
