AI 中文摘要
识别 emergent 通量激发及其与巡游马约拉纳费米子的互统计特征，仍是Kitaev自旋液体研究的核心挑战。我们证明孤立π通量会在电中性马约拉纳连续谱上留下类阿哈罗诺夫-玻姆干涉的本征图案。结合非弹性电子隧穿谱的空间分辨扫描隧道显微镜（STM-IETS），可探测局域动力学自旋响应中随偏置电压和针尖-通量间距变化的该振荡，反映环绕通量的马约拉纳轨迹获得的π相位。我们对Kitaev honeycomb模型的大规模精确对角化及互补的低能连续谱理论，均得到一致的径向振荡结果。这些结果提供了有限能量、空间分辨的隧穿特征，可用于探测已存在的通量，诊断费米子-通量互统计，无需在Kitaev自旋液体中操纵单个任意子。
英文摘要
Identifying emergent flux excitations and signatures of their mutual statistics with itinerant Majorana fermions remains a central challenge in Kitaev spin liquids. We show that an isolated $π$ flux imprints an intrinsic Aharonov-Bohm-like interference pattern on the charge-neutral Majorana continuum. Spatially resolved scanning tunneling microscopy with inelastic electron tunneling spectroscopy (STM-IETS) probes this oscillation in the local dynamical spin response as a function of both bias voltage and tip-flux separation, reflecting the $π$ phase acquired by Majorana trajectories encircling the flux. We show that large-scale exact diagonalization of the Kitaev honeycomb model and a complementary low-energy continuum theory yield consistent radial oscillations. These results provide a finite-energy, spatially resolved tunneling signature of a preexisting flux and a diagnostic of fermion-flux mutual statistics without requiring manipulation of individual anyons in the Kitaev spin liquid.
