• expressed by transmission, for the case of interacting electrons appropriately renormalized [53]. For Kondo-correlated systems, it is the many-body Kondo resonance forming at the Fermi level that enables perfect electron transmission. In the Kondo regime, conductance and many other quantities exhibit

• various other strongly correlated systems described by the Hamiltonian in Equation 1 and characterized by special unitary symmetries. To discuss the correlations, we use the extended Kotliar–Ruckenstein slave boson formalism in the mean-field approximation [10][87][88]. The calculations were carried out

• -correlation functionals for transport calculations [38] and by the high computational cost. Second, standard functionals for DFT do not describe strongly correlated systems particularly well. Third, NEGFs can describe tunneling (hybridization) exactly but naturally lead to perturbative approximations for

• demonstrations, the fine details of the phenomenon were not addressed. Here, we analyze the evolution of vibration-mediated Kondo effect in molecular junctions during mechanical stretching. The described analysis reveals the different contributions of Kondo and inelastic transport. Keywords: correlated systems
