Meron, skyrmion, and vortex crystals in centrosymmetric tetragonal magnets
Zhentao Wang, Ying Su, Shi-Zeng Lin +1
The recent experimental confirmation of a transformation between meron and skyrmion topological spin textures in the chiral magnet CoZnMn [S.-Z. Lin et al., Phys. Rev.…
Large Tunable Anomalous Hall Effect in the Kagom Antiferromagnet URuAl
T. Asaba, Ying Su, M. Janoschek +5
The Berry curvature in magnetic systems is attracting interest due to the potential tunability of topological features via the magnetic structure. -electrons, with their large s…
Stable Higgs mode in anisotropic quantum magnets
Ying Su, A. Masaki-Kato, Wei Zhu +3
Low-energy excitations associated with the amplitude fluctuation of an order parameter in condensed matter systems can mimic the Higgs boson, an elementary particle in the standard…
Current-induced reversal of anomalous Hall conductance in twisted bilayer graphene
Ying Su, Shi-Zeng Lin
It is observed experimentally that the sign of the Hall resistance can be flipped by a dc electric current in the twisted bilayer graphene (TBG) at 3/4 filling of the four-fold deg…
Skyrmion Crystal from RKKY Interaction Mediated by 2D Electron Gas
Zhentao Wang, Ying Su, Shi-Zeng Lin +1
We consider a C invariant lattice of magnetic moments coupled via a Kondo exchange with a 2D electron gas (2DEG). The effective Ruderman-Kittel-Kasuya-Yosida interaction be…
Nontrivial topology and localization in the double exchange model with possible applications to perovskite manganites
Ying Su, Shi-Zeng Lin
The double exchange model describing the coupling between conduction electrons and localized magnetic moments is relevant for a large family of physical systems including manganite…
Pairing symmetry and spontaneous vortex-antivortex lattice in superconducting twisted-bilayer graphene: Bogoliubov-de Gennes approach
Ying Su, Shi-Zeng Lin
We study the superconducting pairing symmetry in twisted bilayer graphene by solving the Bogoliubov-de Gennes equation for all electrons in moiré supercells. With increasing the pa…
