| Once the energy reaches 76 meV, the first lead mode energy is reached and then this mode transmits perfectly, giving a transmission of $1$. | Once the energy reaches 76 meV, the first lead mode energy is reached and then this mode transmits perfectly, giving a transmission of $1$. | ||
| - | As can be seen from ''~\Quantum\wf_probabilities_lead_1_Gamma_0000.fld'', the second and third lead mode states are degenerate due to the symmetry of the lead cross-section. Thus they have the same energy 190 meV. Consequently, the spectrum increases by $2$ at the energy of 190 meV. In this way, the step-like behaviour of the transmission coefficient is explained by lead eigenmodes. | + | As can be seen from ''\Quantum\wf_probabilities_lead_1_Gamma_0000.fld'', the second and third lead mode states are degenerate due to the symmetry of the lead cross-section.
