Terahertz Magnon Excitations and Switching in Non-Collinear Antiferromagnets
Durga Prasad Goli, Se Kwon Kim
We investigate how spatiotemporal spin polarized current can lead to terahertz frequency excitations in non-collinear antiferromagnets. By solving the Landau-Lifshitz-Gilbert equat…
Intersublattice entanglement entropy of ferrimagnetic spin chains
Jongmin Y. Lee, Se Kwon Kim
Ferrimagnets are antiparallel-ordered magnetic states in a bipartite lattice with two alternating unequal spins, which exhibit both ferromagnetic and antiferromagnetic properties.…
Exchange striction induced thermal Hall effect in van der Waals antiferromagnet MnPS
Heejun Yang, Gyungchoon Go, Jaena Park +2
The thermal Hall effect has emerged as an ideal probe for investigating topological phenomena of charge-neutral excitation. Notably, it reveals crucial aspects of spin-lattice coup…
Non-Abelian Gauge Theory for Magnons in Topologically Textured Frustrated Magnets
Ricardo Zarzuela, Se Kwon Kim
We develop an effective gauge theory for three-flavored magnons in frustrated magnets hosting topological textures with the aid of the quaternion representation of the SO(3) order…
Topological magnon-polarons in honeycomb antiferromagnets with spin-flop transition
Gyungchoon Go, Heejun Yang, Je-Geun Park +1
We theoretically investigate the thermal Hall transport of magnon-polarons in a two-dimensional honeycomb antiferromagnetic insulator under the influence of a perpendicular magneti…
