Vector Magnonics: Electrical Injection and Control of Spin Flow in Altermagnets
Yanmeng Lei, Rui-Chun Xiao, Weiwei Lin +1
Altermagnets host chirally split magnons that promise unique functionalities for information processing. However, their distinctive transport signatures, crucial for experimental i…
Ultrastrong magnon-photon coupling in superconductor/antiferromagnet/superconductor heterostructures at terahertz frequencies
V. M. Gordeeva, Yanmeng Lei, Xiyin Ye +4
We predict the realization of ultrastrong coupling between magnons of antiferromagnets and photons in superconductor/antiferromagnet/superconductor heterostructures at terahertz fr…
Observation of Long-Lifetime Magnon Pairs by Fano Resonance of Photons
Qian-Nan Huang, Zhiping Xue, Tao Yu
Mode fluctuations with a long lifetime are essential for quantum information and logic operations in magnonic devices. We probe the broadband nonlinear magnetization dynamics of a…
Ferron-Polaritons in Superconductor/Ferroelectric/Superconductor Heterostructures
M. Nursagatov, Xiyin Ye, G. A. Bobkov +2
We predict the formation of ferron-polariton - a hybrid light-matter quasiparticle arising from the coupling between collective ferroelectric excitations (ferrons) and Swihart phot…
Magnon Correlation Enables Spin Injection, Dephasing, and Transport in Canted Antiferromagnets
Xiyin Ye, Tao Yu
Thermal and electrical injection and transport of magnon spins in magnetic insulators is conventionally understood by the non-equilibrium population of magnons. However, this view…
Chiral Locking of Magnon Flow and Electron Spin Accumulation in Their Near-Field Radiative Spin Transfer
Xi-Han Zhou, Xiyin Ye, Tao Yu
We report a non-contact mechanism for directional injection of magnons in magnetic films when driven by a spin accumulation of electrons of a nearby metallic layer, gove…
