Thus, we propose an improvement of the method, called TPSC+ [3]. The main hypothesis of TPSC+ is that the spin and charge susceptibilities are now dependent on the interacting Green’s function. We show comparisons to benchmarks [3][4] for different quantities for the 2D Hubbard model and discuss the different regions of the phase diagram.
