Terahertz stimulated parametric downconversion of a magnon mode in an antiferromagnet
Zhuquan Zhang, Yu-Che Chien, Man Tou Wong +6
In condensed matter systems, interactions between collective modes offer avenues for nonlinear coherent manipulation of coupled excitations and quantum phases. Antiferromagnets, wi…

Terahertz field-induced nonlinear coupling of two magnon modes in an antiferromagnet
Zhuquan Zhang, Frank Y. Gao, Jonathan B. Curtis +9
Magnons are quantized collective spin-wave excitations in magnetically ordered materials. Revealing their interactions among these collective modes is crucial for the understanding…
