    • The coupling strengths correspond to V=0.2 and W=0.15 for constant coupling functions as used in Ref. 7.

    • note
    • The limit T→∞ is mainly academical since the contribution of assisted hopping decreases with finite temperature, i.e., W→∞ for 1/T→0, due to the broadening of the discrete spectrum of the quantum dot, see Ref. 7.
