Hybrid magnon-phonon cavity for large-amplitude terahertz spin-wave excitation
Shihao Zhuang, Xufeng Zhang, Yujie Zhu +4
Terahertz (THz) spin waves or their quanta, magnons, can be efficiently excited by acoustic phonons because these excitations have similar wavevectors in the THz regime. THz acoust…

Analytical model and dynamical phase-field simulation of terahertz transmission across ferroelectrics
Taorui Chen, Bo Wang, Yujie Zhu +3
We theoretically investigate the steady-state transmission of continuous terahertz (THz) wave across a freestanding ferroelectric slab. Based on the Landau-Ginzburg-Devonshire theo…
