50. 0. Also, we ignore the Klein factors as they can be absorbed into Eqs. (6) disappearing from the analysis.
51. 1, 2 to be the molecular orbitals after the contacting process, there is no need to include the tunneling. However, we assume the dot level wave functions to be those of a free molecule prior to contacting. In that case, there could be some finite overlap, and hence tunneling, between them.
52. Higher Γ would automatically lead to higher Kondo temperatures, which in QD can be as high as several K.48,49 The Kondo physics would then obscure all predicted effects. Therefore, it is essential to keep the system spin-polarized as assumed throughout the paper.
