In numerical simulations of the extended Hubbard model with nearest-neighbor attraction, which is an actively investigated model for high-Tc-superconductors, there has been made observations of time reversal symmetry breaking in the form of loop currents in the last few years. Those loop currents emerge mainly in the vicinity of an s+id-state when nonmagnetic disorder is present in the superconductor. While previous work has focused on the investigation of this phenomenon within the Bogoljubov-de Gennes approximation, we will discuss here the influence electronic correlations on the stability of the loop currents. This is accomplished via the Gutzwiller approximation extended towards the inclusion of pairing correlations.
