Projector, Neural, and Tensor-Network Representations of Cluster and Dipolar-cluster SPT States
Seungho Lee, Daesik Kim, Hyun-Yong Lee +1
The cluster-state wavefunction, a paradigmatic example of symmetry-protected topological (SPT) order with symmetry, is expressed i…
Effective Field Theory of a Noncollinear Altermagnet
Seungho Lee, Se Kwon Kim
We derive an effective field theory for a noncollinear altermagnet and magnons on top of the noncollinear ground state from an altermagnetic Heisenberg model. We obtain the ground-…
Stable singular fractional skyrmion spin texture from the quantum Kelvin-Helmholtz instability
SeungJung Huh, Wooyoung Yun, Gabin Yun +7
Topology profoundly influences diverse fields of science, providing a powerful framework for classifying phases of matter and predicting nontrivial excitations, such as solitons, v…
Domain Wall Networks as Skyrmion Crystals in Chiral Magnets
Seungho Lee, Toshiaki Fujimori, Muneto Nitta +1
We theoretically investigate the ground states of a chiral magnet with a square anisotropy and show that it supports domain wall networks as stable ground states. A domain wall jun…
Magnon dynamics in a Skyrmion-textured domain wall of antiferromagnets
Seungho Lee, Kouki Nakata, Oleg Tchernyshyov +1
We theoretically investigate the interaction between magnons and a Skyrmion-textured domain wall in a two-dimensional antiferromagnet and elucidate the resultant properties of magn…
Orbital angular momentum and current-induced motion of a Skyrmion-textured domain wall in a ferromagnetic nanotube
Seungho Lee, Se Kwon Kim
We theoretically study the current-induced dynamics of a domain wall in a ferromagnetic nanotube by developing a theory for the orbital angular momentum of a domain wall and the cu…
