Plaid-Like Spin Splitting and Chirality of Magnon Bands in Antiferromagnetic MnTe
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…

Consistent Evaluation of Operators Involving the Position Operator in the Bloch Representation: Application to the Orbital Moment
Daehyeon An, Junmo Jeon, Se Kwon Kim
The position operator plays a central role in condensed-matter observables such as velocity, orbital moment, and electric polarization. In solid-state physics, the evaluation of op…

Intrinsic Nernst effect of the magnon orbital moment in a honeycomb ferromagnet
Daehyeon An, Se Kwon Kim
The Nernst effect of the magnon orbital moment is theoretically investigated in a honeycomb ferromagnet, whose Hamiltonian contains the Heisenberg exchange, the Dzyaloshinskii-Mori…
