论文摘要
我们采用时间依赖的真实空间局部密度 - 基于多体状态的时间演变,研究Majorana零模式的运动和融合。 我们使用时间相关电位分析了Majoanas的动力学和两个融合通道,即创建{\ it Walls}或{\ it wells}。集中于局部密度和费米的电荷密度随时间而变化的%。对于快速移动的Mapoanas,我们推出了``强零模式''操作员的非平衡标志(全光谱中的准平等性退化性),并且在存在排斥性库仑相互作用的情况下进行了分解。融合后,我们还专注于形成一个完整的电子,我们还讨论了减少非绝热效应所需的主要和下限速度,并避免由于腐蚀而造成中毒。
We employ a time-dependent real-space local density-of-states method to study the movement and fusion of Majorana zero modes in the 1D interacting Kitaev model, based on the time evolution of many-body states. We analyze the dynamics and both fusion channels of Majoranas using time-dependent potentials, either creating {\it Walls} or {\it Wells}. % focusing on the local density-of-states and charge-density of fermions varying with time. For fast moving Majoranas, we unveil non-equilibrium signatures of the ``strong-zero mode'' operator (quasi parity degeneracy in the full spectrum) and its breakdown in the presence of repulsive Coulomb interactions. Focusing on forming a full electron after fusion, we also discuss upper and lower limits on the Majorana speed needed to reduce non-adiabatic effects and to avoid poisoning due to decoherence.
