Antiferro-Chiral Phonons as Conjugate Fields to Néel Order in $\mathcal{P}\mathcal{T}$-Symmetric Antiferromagnets

Sanjib Kumar Das, Randy Yeh, Yafei Ren +1

Chiral phonons act as a phononic conjugate field to net magnetization, enabling phononic detection and control of ferromagnetic order. Whether an analogous phononic coupling exists…
