Ferromagnetic Bloch Line as a Bead on a String
Jake Hoffmann, Oleg Tchernyshyov
We present a simple model of a Bloch line in a thin-film ferromagnet with strong easy-axis and intermediate in-plane anisotropies. The meron is represented as a charged, massless p…
Spin Excitation Continuum in the Exactly Solvable Triangular-Lattice Spin Liquid CeMgAl11O19
Bin Gao, Tong Chen, Chunxiao Liu +17
In magnetically ordered insulators, elementary quasiparticles manifest as spin waves - collective motions of localized magnetic moments propagating through the lattice - observed v…
Helical edge modes in a triangular Heisenberg antiferromagnet
Bastian Pradenas, Grigor Adamyan, Oleg Tchernyshyov
We investigate the emergence of helical edge modes in a Heisenberg antiferromagnet on a triangular lattice, driven by a topological mechanism similar to that proposed by Dong et al…
Hall mass and transverse Noether spin currents in noncollinear antiferromagnets
Luke Wernert, Bastián Pradenas, Oleg Tchernyshyov +1
Noncollinear antiferromagnets (AFMs) have recently attracted attention in the emerging field of antiferromagnetic spintronics because of their various interesting properties. Due t…
Field theory of collinear and noncollinear magnetic order
Oleg Tchernyshyov
These lecture notes from the 2023 Summer "School Principles and Applications of Symmetry in Magnetism" introduce the reader to the classical field theory of ferromagnets and antife…
Spin-frame field theory of a three-sublattice antiferromagnet
Bastian Pradenas, Oleg Tchernyshyov
We present a nonlinear field theory of a three-sublattice hexagonal antiferromagnet. The order parameter is the spin frame, an orthogonal triplet of vectors related to sublattice m…
