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…

Spontaneous symmetry breaking in the Heisenberg antiferromagnet on a triangular lattice
Bastián Pradenas, Grigor Adamyan, Oleg Tchernyshyov
We present a detailed investigation of an overlooked symmetry structure in non-collinear antiferromagnets that gives rise to an emergent quantum number for magnons. Focusing on the…

Antichiral spin order its Goldstone modes and their hybridization with phonons in the topological semimetal Mn3Ge
Y. Chen, J. Gaudet, S. Dasgupta +11
Quantum materials with strong transport responses to disparate physical quantities are of great fundamental significance and may hold technological potentials. The interplay betwee…
