Windmill Spin Dynamics and Its Induced Anomalous Hall Effect in Noncollinear Antiferromagnet Mn3Sn
Jikun Zhou, Yang Gao, Qian Niu
We demonstrate that the spin dynamics of the noncollinear antiferromagnet Mn3Sn hosts a soft eigenmode that transitions from small-angle oscillation to a large-angle, chiral windmi…
High-Performance Quantum Frequency Conversion from Ultraviolet to Telecom Band
Yi Yang, Bin Wang, Ji-Chao Lin +10
Quantum frequency conversion (QFC) is essential for bridging the spectral gap between stationary qubits and low-loss optical communication channels. In this work, we demonstrate a…
Anisotropic Gyromagnetic Ratio and Orthogonal Einstein-de Haas Effect
Rui Xue, Zhenhua Qiao, Yang Gao +1
We theoretically demonstrate an orthogonal Einstein-de Haas effect, where the rotation of ferromagnetic materials is caused by the change of magnetization in the direction orthogon…
Atomic-scale spin sensing of a 2D -wave altermagnet via helical tunneling
Zhuying Wang, Shuikang Yu, Xingkai Cheng +17
Altermagnetism simultaneously possesses nonrelativistic spin responses and zero net magnetization, thus combining advantages of ferromagnetism and antiferromagnetism. This superior…
Frequency Domain Berry Curvature Effect on Time Refraction
Shiyue Deng, Yang Gao, Qian Niu
We demonstrate that there exist frequency domain Berry curvature in the wave function of photons in dispersive optical systems. This property arises from the frequency dispersion o…
Extrinsic Mechanisms of Phonon Magnetic Moment
Rui Xue, Zhenhua Qiao, Yang Gao +1
We develop a general formalism of phonon magnetic moment by including the relaxation process. We then identify the skew-scattering and side-jump contributions to the phonon magneti…
Magnon Thermal Hall Effect Induced By Symmetric Exchange Interaction
Jikun Zhou, Yang Gao, Qian Niu
By analyzing the spin-group symmetry of magnons, we establish two generalized Onsager's relations in the magnon thermal Hall effect, which reveals the rich and complicated structur…
