Nonlinear Magnon Magnetic Moment Transport in Triangular-Lattice f-Wave Antialtermagnets
Volodymyr P. Kravchuk, Kostiantyn V. Yershov, Bastián Pradenas +6
We study the spin excitations in the frustrated coplanar 120-degree ground state of the triangular-lattice Heisenberg antiferromagnet and demonstrate that they carry a magnetic mom…

Geometric Spin Rotation in Triangular Antiferromagnets
Grigor Adamyan, Bastian Pradenas, Boris Ivanov +1
We describe a geometric phenomenon in which a traveling wave made of degenerate Goldstone modes leaves behind a transformed ground state. In a triangular Heisenberg antiferromagnet…
