自2021年以来,华中科技大学的于涛教授建立了一个以“手性作为一种广义自旋-轨道相互作用”概念为核心的内在连贯的理论框架。围绕此概念的研究已系统地总结于 Physics Reports 的三篇长篇综述文章:“Chirality as a Generalized Spin-Orbit Interaction in Spintronics” (2023),“Non-Hermitian Topological Magnonics” (2024), 和 “Electromagnetic Proximity Effects at Heterointerfaces” (2026)。通过揭示其在磁学、自旋电子学、轨道电子学、非常规超导、铁电学及其相互关联中的相关物理效应,于涛已在同行评审期刊上发表70余篇论文,包括 Physics Reports (3篇), Physical Review Letters (9篇), Physical Review (42篇), Science Advances (2篇), Nature Physics (1篇) 和 Science China Physics, Mechanics & Astronomy (2篇),累计获得超过3700次正面引用。

 

于涛研究的一个标志性特征是其强大的预测能力和与实验的紧密联系。过去五年间,于涛课题组的多个理论预测已被国际实验团队所验证。这些预测包括:混合超导体-迈斯纳-磁子集体模、超导约瑟夫森结中铁磁共振的巨大频率偏移、磁子热晶体管的概念、铁电体中铁振子的双曲激发、磁动力学激发的声表面波、微波的磁致单向完美吸收,以及交变磁体磁子中的自旋塞贝克效应。

 

该框架的基础是倏逝波的普适手性定理,其表述见 [Cai et al., Spin-orbit-locked coupling of localized microwaves to magnons, Phys. Rev. Applied 22, 034042 (2024)]。该定理证明,任何在表面或界面处的倏逝矢量场均具有固有且确定的手性,即倏逝波的自旋角动量、其衰减方向(指向界面外)和传播波矢通过一个确定性的右手定则锁定在一起。这一见解将手性从一种材料特性提升为一种基本的几何属性,并为理解和设计从手性光-物质相互作用、近场能量转移到自旋与轨道角动量转换等一系列界面现象提供了一个统一的、基于第一性原理的原则。

 

在此手性框架内,手性自旋与轨道泵浦研究取得了显著进展。它提出了由倏逝电磁场产生横向和单向电子自旋泵浦的新机制,揭示了驱动场的极化和传播方向如何控制所产生纯自旋流的方向性和极化 [Li et al., Transverse and Unidirectional Spin Pumping, PRB 113, 014438 (2026)]。近场使得探索完全不依赖于自旋轨道耦合的轨道泵浦效应成为可能,证明了轨道角动量可以通过轨道织构直接、高效地跨界面传递 [Cai et al., Evanescent Orbital Pumping by Magnetization Dynamics Free of Spin-Orbit Coupling, Science China Physics, Mechanics & Astronomy 69, 237511 (2026)]。此外,该理论提出了声子介导的自旋泵浦机制,即在直接电子耦合较弱的异质结中,晶格振动(声子)可产生自旋流,从而扩展了复杂材料体系中自旋流产生的物理工具箱 [Cai et al., Acoustic Frequency Multiplication and Pure Second Harmonic Generation of Phonons by Magnetic Transducers. PRB 107, L100410 (2023); Cao et al., Inverse acoustic spin Hall effect in heavy metal /ferromagnet bilayers, PRL 135, 246705 (2025)]。

 

该框架的适用性也延伸至动态体效应。它成功预测了由磁子拖曳诱导的自旋波多普勒频移,这是一种体输运现象,即磁子的净流动可以拖曳自旋波,从而有效改变其频率,类似于声波的多普勒效应 [Yu et al., Spin-Wave Doppler Shift by Magnon Drag in Magnetic Insulators, PRL 126, 137202 (2021)]。在量子信息技术领域的延伸研究中,一对NV色心自旋量子比特在磁性纳米线中以手性方式交换虚磁子,从而产生定向量子纠缠 [Xue et al., Directional entanglement of spin-orbit locked nitrogen-vacancy centers by magnons, PRB 112, 094438 (2025)]。

 

普适手性激发了于涛在超导磁子学领域的开创性工作,其预测了磁子与邻近超导体中超电流之间通过非局域迈斯纳效应介导的手性超强耦合 [Yu and Bauer, Efficient Gating of Magnons by Proximity Superconductors. PRL 129, 117201 (2022)]。这种源于超电流手性近场的独特耦合,使得对磁子流的非接触、电学门控成为可能,理论上预测其效率接近百分之百。该预测随后被一个荷兰-德国联合小组通过观测铁磁绝缘体与超导体界面处的混合磁子-迈斯纳集体模所实验证实 [Borst et al., Science 382, 430 (2023)]。该框架的进一步理论预测,包括当铁磁体/反铁磁体置于超导约瑟夫森结中时,铁磁共振频率的巨大偏移 [Zhou and Yu, Gating ferromagnetic resonance of magnetic insulators by superconductors via modulating electric field radiation, PRB 108, 144405 (2023); Qiu et al., Persistent nodal magnon-photon polariton in ferromagnetic heterostructures, PRB 110, 184403 (2024); Gordeeva et al., Ultrastrong magnon-photon coupling in superconductor/antiferromagnet/ superconductor heterostructures at terahertz frequencies, PRB 113, 134418 (2026)],以及由超导体显著增强的磁子输运 [Zhou et al., Giant Enhancement of Magnon Transport by Superconductor Meissner Screening. PRB 110, L020404 (2024)],也都得到了强有力的实验支持。此外,手性概念被应用于强关联电子系统,提出手性d+id超导基态可能是魔角扭曲双层石墨烯中观测到的电子向列性和时间反演对称性破缺的起源 [Yu et al., Nematicity Arising from a Chiral Superconducting Ground State in Magic-Angle Twisted Bilayer Graphene under In-Plane Magnetic Fields, PRL 127, 127001 (2021)]。这些关于超导邻近效应的研究共同构成了一个更广泛的、关于材料异质界面处电磁邻近效应的统一理论的核心组成部分。

 

手性与非互易性密切相关,并因此自然地延伸至新兴的非厄米拓扑磁子学领域,其中增益、损耗和非互易耦合起主导作用。在此研究方向,于涛与合作者早期就提供了一个具有影响力的理论演示,展示了磁性链中定制的的手性相互作用如何诱导磁子的非厄米趋肤效应 [Yu and Zeng, Giant Microwave Sensitivity of Magnetic Array by Long-Range Chiral Interaction Driven Skin Effect, PRB 105, L180401, 2022]。在此效应中,所有磁子本征态(包括对应体模的态)都指数局域于系统的一个边界,这显著偏离了厄米系统的传统体边对应关系。这项工作凸显了此类非厄米拓扑在基于这些局域边界模(可汇聚能量)的应用潜力,例如超灵敏微波传感。后续研究详细阐述了如何在二维磁性单元(如纳米盘)阵列中实现并动态调控可调的边缘和角落趋肤效应,为以可重构方式操控和引导微波能量流提供了一个多功能平台 [Cai et al., Edge and corner skin effects of chirally coupled magnons characterized by a topological winding tuple. PRB 108, 174421 (2023)]。探索还延伸到非厄米磁子晶格中拓扑惰性缺陷态的存在性和鲁棒性,由于其抗特定扰动的特性,这些态可能用作量子信息存储的保护模 [Zeng and Yu, Radiation-free and non-Hermitian topology inertial defect states of on-chip magnons. Physical Review Research 5, 013003 (2023)]。在此框架内的相关理论提案包括微波单向完美吸收器的设计(其中入射辐射从一个方向被完美吸收但从另一方向被反射),以及手性使能的热磁子晶体管 [Yu et al., Chirality Enables Thermal Magnon Transistors. Science China Physics, Mechanics & Astronomy 67, 247511 (2024)],它利用非互易耦合以一个磁子流控制另一个磁子流,阐明了利用磁系统中非厄米拓扑可以实现的新奇器件功能。

 

基于手性和对称性的框架的解释和预测能力,在反铁磁自旋电子学这一快速发展的领域中,通过发展磁子自旋输运的统一理论,得到了进一步证明。这里的一个关键技术进展是引入了磁子自旋的矩阵描述,它提供了一个强大而普适的数学工具,用于分类自旋输运现象、计算响应函数以及预测超越传统赝矢量描述的新效应 [Ye and Yu, Magnon correlation enables spin injection, dephasing, and transport in canted antiferromagnets, PRB 112, 224417 (2025)]。将这一统一工具应用于新兴的交变磁体类别(即具有补偿磁序但动量依赖自旋劈裂的材料)时,该理论预测了在没有外磁场的情况下也可能存在的超大自旋塞贝克效应和自旋能斯特效应,这直接源于这些材料独特的动量依赖自旋劈裂 [Cui et al., Efficient Spin Seebeck and Spin Nernst Effects of Magnons in Altermagnets, PRB 108, L180401 (2023)]。此预测后来被南京大学的课题组实验验证。对于反铁磁体等非共线磁体,该框架优雅地解释了由隐藏Dzyaloshinskii-Moriya相互作用引起的磁子自旋猝灭效应,并揭示了对称性保护的“节点自旋”的存在——即动量空间中磁子自旋织构为零的特定点或线,这导致了独特的输运特征 [Ye et al., Spin quenching and transport by hidden Dzyaloshinskii-Moriya interactions, PRB 111, 064401 (2025)]。

 

在磁子学方面的专业知识已成功扩展到一个根本不同的序参量——电极化,从而开创了“铁振子学”领域,即对铁电极化波量子(铁振子)的研究。于涛与合作者理论预测了具有定向、手性近场的表面铁振子模的存在,它们不同于磁性表面波(Damon-Eshbach模)[Zhou et al., Surface Ferron Excitations in Ferroelectrics and Their Directional Routing, CPL 40, 087103 (2023)]。这一关于手性表面铁振子的预测已在铁电范德华材料中得到实验验证。随后的薄膜计算也证实了表面铁振子模 [Rodríguez-Suárez et al., Surface and volume modes of polarization waves in thin ferroelectric films. PRB 109, 134307 (2024)]。基于非线性铁振子动力学(例如频率梳)的新型太赫兹器件提案也在积极探索中,利用了铁振子与太赫兹辐射之间的强耦合。

 

这些研究的全球影响力通过积极、持续的国际合作得到了显著增强。重要的合作伙伴包括Gerrit Bauer教授与Irina Bobkova教授在超导自旋电子学和铁振子学方面的持续合作,以及遍及欧洲(德国、荷兰、西班牙)和日本的协作网络。这个广泛的网络在关键预测的实验验证、先进材料合成、纳米加工和测量技术的获取方面起到了关键作用。

 

于涛教授主导的研究建立了一个围绕手性物理、非厄米拓扑和电磁邻近效应这三个相互关联的支柱而组织的、连贯而广阔的理论体系。它提供了一个统一的概念视角,用于理解跨越磁性、超导和铁电材料的多样化量子现象,并为在量子物质中发现和设计新的手性、拓扑及非厄米态,提供了一条基于预测的实用路线图。
