Fig. 2(Color online) (a) Calculated eigen energies (N = 1–9) of quantum dot, formed by trident shaped electrodes ((b)), as a function of deformation factor βC. Deformation factor βC is converted from biased voltage. Eigenvalues of the same sequence are displayed with the same color. The regions where crossing of eigen energies occurs are marked in C, and avoided crossing are marked in A, B. (b) Figure showing the region around point C1 separately. (c) Table of wave functions of degenerated eigenvalues in the region of C1, C2, C3.
