Asymmetric splitting of an antiferromagnetic resonance via quartic exchange interactions in multiferroic hexagonal HoMnO
N. J. Laurita, Yi Luo, Rongwei Hu +4
The symmetric splitting of two spin-wave branches in an antiferromagnetic resonance (AFR) experiment has been an essential measurement of antiferromagnets for over half a century.…
Projective symmetry of partons in Kitaev's honeycomb model
Paula Mellado, Olga Petrova, Oleg Tchernyshyov
Low-energy states of quantum spin liquids are thought to involve partons living in a gauge-field background. We study the spectrum of Majorana fermions of Kitaev's honeycomb model…
Unpaired Majorana modes on dislocations and string defects in Kitaev's honeycomb model
Olga Petrova, Paula Mellado, Oleg Tchernyshyov
We study the gapped phase of Kitaev's honeycomb model (a spin liquid) on a lattice with topological defects. We find that some dislocations and string defects carry unpaired…
Propulsion of a domain wall in an antiferromagnet by magnons
Se Kwon Kim, Yaroslav Tserkovnyak, Oleg Tchernyshyov
We analyze the dynamics of a domain wall in an easy-axis antiferromagnet driven by circularly polarized magnons. Magnons pass through a stationary domain wall without reflection an…
Low Energy Electrodynamics of Novel Spin Excitations in the Quantum Spin Ice YbTiO
LiDong Pan, Se Kwon Kim, A. Ghosh +7
In condensed matter systems, the formation of long range order (LRO) with broken symmetry is often accompanied by new types of excitations. However, in many magnetic pyrochlore oxi…
Structure factor of low-energy spin excitations in a S=1/2 kagome antiferromagnet
Zhihao Hao, Oleg Tchernyshyov
The ground state of the S=1/2 Heisenberg antiferomagnet on kagome can be viewed as a collection of fermionic spinons bound into small, heavy singlet pairs. Low-energy magnetic exci…
