Quantum conductance map for the two-orbital Anderson-Holstein model as a function of energy level of the dots and e-ph coupling. Different many-body resonances are visible: the orbital Kondo effects (K+, K-), local spin singlet state (LSS), spin-orbital Kondo effects (SOK, 2K) and the polaronic charge-orbital Kondo state (COK).
