N2 - We study the transport properties of a double quantum dot (DQD) molecule at zero and at finite temperature. The properties of the zero-temperature conductance depend on whether the level attraction between the symmetric and antisymmetric states of the DQD, produced by the coupling to the leads, exceeds or not the interdot tunneling. For finite temperature, we find a remarkable nonthermal broadening effect of the conductance resonance when the energy levels of the individual dots are detuned.
