Exact dynamical correlations of nonlocal operators in quadratic open Fermion systems: a characteristic function approach
The dynamical correlations of nonlocal operators in general quadratic open fermion systems is still a challenging problem. Here we tackle this problem by developing a new formulation of open fermion many-body systems, namely, the characteristic function approach. Illustrating the technique, we analy...
