Strong coupling between antiferromagnetic magnons and spoof surface plasmons
Yamin Sun, Ka Shen, H. Y. Yuan
Hybrid magnonic system provides a versatile platform for coherent information exchange between spin excitations and other physical degrees of freedom. While strong coupling between…
Quantum Entanglement and Teleportation of Magnons in Coupled Spin Chains
Zian Xia, Ruoban Ma, Chang Shu +2
This study explores how entanglement and quantum teleportation of magnons can be achieved in coupled spin chain systems. By utilizing different magnetic configurations, we show tha…
Macroscopic entanglement between localized domain walls inside a cavity
Rahul Gupta, H. Y. Yuan, Himadri Shekhar Dhar
We present a scheme for generating stable and tunable entanglement between two localized Bloch domain walls in nanomagnetic strips kept inside a chiral optical cavity. The entangle…
Using surface plasmons to detect spin inertia
H. Y. Yuan
Recent experiments demonstrate that spin dynamics may acquire an inertial effect in a few metallic magnets, deviating from the traditional inertia-free dynamics. It remains an open…
Plasmon-Driven Giant Amplification of Ultrashort Spin Current
H. Y. Yuan, Rembert A. Duine
A key challenge in spintronics is to efficiently generate and manipulate spin current for information processing. Here we study ultrashort spin transport and associated terahertz (…
Quantum entanglement and Einstein-Podolsky-Rosen steering in magnon frequency comb
Qianjun Zheng, H. Y. Yuan, Yunshan Cao +1
Significant progress has been made for the emerging concept of magnon frequency comb (MFC) but mainly in the classical region. The quantum property of the comb structure is yet to…
