Coherent Magnons Driven by Photomodulated Anisotropy in Altermagnetic MnTe

Dingbin Huang, Jonathon Kruppe, Resham Babu Regmi +3

Manganese telluride ($\text{MnTe}$) has recently emerged as a prototypical $g$-wave altermagnet, providing an ideal platform to investigate the non-equilibrium excitations of alter…
