Raman Circular Dichroism Reveals Higher-Order Quantum Geometry of Magnons

Yong Chan Kim, Youngsu Choi, Kwang-Yong Choi +1

We develop a gauge-invariant framework that relates two-magnon Raman circular dichroism (RCD) to higher-order magnon quantum geometry. In the magnon band basis, the Raman operator…

Plaid-Like Spin Splitting and Chirality of Magnon Bands in Antiferromagnetic MnTe $_{2}$

Dirk Wulferding, Daehyeon An, Jiwon Choi +8

Altermagnets constitute an emerging class of magnetic materials that combine compensated antiferromagnetic order with spin-split excitations arising from crystalline symmetries. De…
