AI 中文摘要
反铁磁自旋波的低能动力学可映射为有质量的克莱因-戈登标量场，为模拟视界物理提供了固态平台。研究表明，非均匀自旋电流会产生有效磁子流，能够形成黑洞和白洞视界；视界对腔室表现出共振输运，以及由磁子-反磁子混合介导的类超辐射放大。核心结果是，亚磁子区与超磁子区的周期性排列形成非互易磁子晶体，进入超磁子态后可获得负模传播通道，使体带隙闭合并重新打开，这一过程由扎基相位的变化和混合磁子-反磁子边缘态的出现所表征，该研究在模拟视界物理与拓扑磁子学之间建立了直接联系，为电调控磁子能带拓扑提供了可行途径。
英文摘要
The low-energy dynamics of antiferromagnetic spin waves map onto a massive Klein-Gordon scalar field, providing a solid-state platform for analogue-horizon physics. We show that an inhomogeneous spin current generates an effective magnon flow capable of forming black- and white-hole horizons. Horizon-pair cavities exhibit resonant transport and superradiant-like amplification mediated by magnon-antimagnon mixing. Our central result is that a periodic arrangement of submagnonic and supermagnonic regions forms a non-reciprocal magnonic crystal in which entering the supermagnonic regime makes negative-norm propagating channels available and enables the bulk gap to close and reopen. This drives a topological transition characterized by a change in the Zak phase and the emergence of a hybrid magnon-antimagnon edge state. These results establish a direct connection between analogue-horizon physics and topological magnonics, providing an electrically tunable route for controlling magnonic band topology.
