Acoustic attenuation in magnetic insulator films: effects of magnon polaron formation
Shihao Zhuang, Jia-Mian Hu
A magnon and a phonon are the quanta of spin wave and lattice wave, respectively, and they can hybridize into a magnon polaron when their frequencies and wavenumbers match close en…

Role of Polarization-Photon Coupling in Ultrafast Terahertz Excitation of Ferroelectrics
Shihao Zhuang, Jia-Mian Hu
We investigate the role of polarization-photon coupling (specifically, polarization-oscillation-induced radiation electric field) in the excitation of ferroelectric thin films by a…

Excitation and detection of coherent sub-terahertz magnons in ferromagnetic and antiferromagnetic heterostructures
Shihao Zhuang, Jia-Mian Hu
Excitation of coherent high-frequency magnons (quanta of spin waves) is critical to the development of high-speed magnonic devices. Here we computationally demonstrate the excitati…
