Symmetric Improved Estimators for Continuous-time Quantum Monte Carlo
Josef Kaufmann, Patrik Gunacker, Alexander Kowalski +2
We derive equations of motion for Green's functions of the multi-orbital Anderson impurity model by differentiating symmetrically with respect to all time arguments. The resulting…
