摘要

非阿贝尔任子对应于具有多个融合通道和非交换编织统计量的集体激发,是拓扑量子计算的基本成分。在这里,我们揭示了由斐波那契子的非阿贝尔融合诱发的奇异布洛赫振荡(BOs)。研究表明,与聚变相关的内部能级和外力之间的相互作用可以诱发不同周期的布洛赫振荡和耦合聚变度的布洛赫-齐纳振荡(BZOs)。在这种情况下,核聚变矩阵的黄金比率可以由BOs或BZOs与外力作用的周期来决定,从而提供了一种解除非阿贝尔核聚变的有效方法。此外,我们还通过将两个斐波那契任子的薛定谔方程映射到电路的动力学方程上,在实验中模拟了非阿贝尔聚变BO。通过测量阻抗谱和电压演化,我们模拟了依赖聚变的 BZO 和 BO。我们的发现建立了 BO 与非阿贝尔聚变之间的联系,为模拟与非阿贝尔物理学相关的众多有趣现象提供了一个通用平台。

Bloch oscillations of Fibonacci anyons
Non-Abelian anyons, which correspond to collective excitations possessing multiple fusion channels and noncommuting braiding statistics, serve as the fundamental constituents for topological quantum computation. Here, we reveal the exotic Bloch oscillations (BOs) induced by non-Abelian fusion of Fibonacci anyons. It is shown that the interplay between fusion-dependent internal energy levels and external forces can induce BOs and Bloch-Zener oscillations (BZOs) of coupled fusion degrees with varying periods. In this case, the golden ratio of the fusion matrix can be determined by the period of BOs or BZOs in conjunction with external forces, giving rise to an effective way to unravel non-Abelian fusion. Furthermore, we experimentally simulate nonAbelian fusion BOs by mapping Schrodinger equation of two Fibonacci anyons onto dynamical equation of electric circuits. Through the measurement of impedance spectra and voltage evolution, both fusion-dependent BZOs and BOs are simulated. Our findings establish a connection between BOs and non-Abelian fusion, providing a versatile platform for simulating numerous intriguing phenomena associated with non-Abelian physics.
