论文摘要
探索了近端核壳纳米线中超导间隙的通量周期性振荡。比较圆柱纳米线的能量光谱中振荡的周期性与具有六边形和方形横截面几何形状的纳米线，以及Zeeman和Rashba旋转轨道相互作用的影响。发现H/E和H/2E周期性之间的过渡，并证明取决于化学势，并与角动量量子数的退化点相对应。对于正方形纳米线的薄外壳，在无限的线光谱中仅发现H/E周期性，并显示出是由于最低激发态组之间的能量分离而导致的。
Flux-periodic oscillations of the superconducting gap in proximitized core-shell nanowires are explored. Periodicity of oscillations in the energy spectrum of a cylindrical nanowire is compared with nanowires having hexagonal and square cross-section geometry, along with the effects of Zeeman and Rashba spin-orbit interaction. A transition between h/e and h/2e periodicity is found and shown to be dependent on the chemical potential, with correspondence to degeneracy points of the angular momentum quantum number. For a thin shell of a square nanowire, solely h/e periodicity is found in the infinite wire spectrum and shown to result from energy separation between the lowest groups of excited states.
