Based on a model Hamiltonian including the on-site repulsive interaction among the electrons, we investigate the flux-dependent evolution of mixed pairing orders in mesoscopic superconducting square loops by numerically solving the Bogoliubov-de Gennes equations. The influence of centered hole size on the order modulation is mainly discussed. For the emergent spin-triplet p-wave and subdominant spin-singlet d-wave pairing states in the present loop system with an enlarged hole size, the order-parameter patterns always behave the diagonal symmetry. In addition, the obtained vortical and skyrmionic configurations inside the sample along one of diagonal directions can be effectively tuned by the chosen chemical potential and the next-nearest-neighbor hopping effect.

介观超导方环中混合配对的磁通依赖演化

基于包含电子之间的现场排斥相互作用的哈密顿量模型,我们通过数值求解Bogoliubov-de Gennes方程,研究了介观超导正方形环中混合配对的磁通依赖演化。主要讨论了中心孔尺寸对阶跃调制的影响。对于紧急自旋三胞胎p波和主要自旋单峰 d在具有增大的孔尺寸的当前环路系统中,如果波成对状态,则顺序参数模式始终表现出对角对称性。另外,通过选择的化学势和最近邻跳变效应,可以有效地调整沿对角线方向之一在样品内部获得的涡旋和空中离子构型。
