(a) The linear conductance G as a function of charge energy ε for t = 0 (solid line), t = 0.01 (dashed line), and t = 0.08 (dotted line). (b) and (c) Charge occupation of the transformed orbits f i ( i = a,b,c ) as functions of ε for t = 0.01 (panel (b)) and t = 0.08 (panel (c)). Here, the remaining parameters are the same as those in Fig. 5 .
