Transverse and Unidirectional Spin Pumping
Ping Li, Chengyuan Cai, Tao Yu
Conventional spin pumping, driven by magnetization dynamics, is longitudinal since the pumped spin current flows normal to the interface between the ferromagnet and the conductor.…
Directional entanglement of spin-orbit locked nitrogen-vacancy centers by magnons
Zhiping Xue, Ji Zou, Chengyuan Cai +2
We address that the stray magnetic field emitted by the excited quantum states of the nitrogen-vacancy (NV) centers is spin-momentum locked, such that the spin transfer to nearby f…
Evanescent Orbital Pumping by Magnetization Dynamics Free of Spin-Orbit Coupling
Chengyuan Cai, Hanchen Wang, Tao Yu
Converting magnetization spin to orbital current often relies on strong spin-orbit interaction that may cause additional angular momentum dissipation. We report that coherent magne…
Spin-orbit locking of magnons with localized microwave fields
Chengyuan Cai, Zubiao Zhang, Ji Zou +2
We address the photonic spin-orbit coupling known from nano-optics and plasmonics in the microwave regime. The spin and momentum of microwaves emitted by…
Spin Radiation of Electrons, Excitons, and Phonons
Chengyuan Cai, Tao Yu
In the celebrated Stern-Gerlach experiment an inhomogeneous static magnetic field separates a beam of charge-neutral atoms with opposite spins, thereby driving a ``spin current" no…
Edge and corner skin effects of chirally coupled magnons characterized by a topological winding tuple
Chengyuan Cai, Dante M. Kennes, Michael A. Sentef +1
We investigate a long-ranged coupled and non-Hermitian two-dimensional array of nanomagnets, fabricated on a thin magnetic substrate and subjected to an in-plane magnetic field. We…
Expanding Scope: Adapting English Adversarial Attacks to Chinese
Hanyu Liu, Chengyuan Cai, Yanjun Qi
Recent studies have revealed that NLP predictive models are vulnerable to adversarial attacks. Most existing studies focused on designing attacks to evaluate the robustness of NLP…
Chirality Enables Thermal Magnon Transistors
Tao Yu, Chengyuan Cai, Gerrit E. W. Bauer
We report a theory of thermal spin pumping into proximity magnets under a transverse-bias-driven heat flow of magnons in magnetic films when the dipolar coupling to the magnetic ga…
Acoustic Frequency Multiplication and Pure Second Harmonic Generation of Phonons by Magnetic Transducers
Chengyuan Cai, Xi-Han Zhou, Weichao Yu +1
We predict frequency multiplication of surface acoustic waves in dielectric substrates via the ferromagnetic resonance of adjacent magnetic transducers when driven by microwaves. W…
Surface Ferron Excitations in Ferroelectrics and Their Directional Routing
Xi-Han Zhou, Chengyuan Cai, Ping Tang +4
The duality between the electric and magnetic dipoles inspires recent comparisons between ferronics and magnonics. Here we predict surface polarization waves or ``ferrons" in ferro…
