Magnetic Quadrupole Lens and Current-Induced Quadrupolar Dynamics of Antiskyrmion
Linfeng Du, Yang Liu, Peng Yan +1
We demonstrate that antiskyrmions can serve as magnetic quadrupole lenses that focus or defocus electric currents traversing them. We showcase the antiskyrmion core as a focal poin…
Exciton Superposition across Moiré States in a Semiconducting Moiré Superlattice
Zhen Lian, Dongxue Chen, Yuze Meng +9
Moiré superlattices of semiconducting transition metal dichalcogenides (TMDCs) enable unprecedented spatial control of electron wavefunctions in an artificial lattice with periodic…
Quadrupolar Excitons and Hybridized Interlayer Mott Insulator in a Trilayer Moiré Superlattice
Zhen Lian, Dongxue Chen, Lei Ma +13
Transition metal dichalcogenide (TMDC) moiré superlattices, owing to the moiré flatbands and strong correlation, can host periodic electron crystals and fascinating correlated phys…
Massive Dirac fermions in moiré superlattices: a route towards topological flat minibands
Ying Su, Heqiu Li, Chuanwei Zhang +2
We demonstrate a generic mechanism to realize topological flat minibands by confining massive Dirac fermions in a periodic moiré potential, which can be achieved in a heterobilayer…
Tunable lattice reconstruction and bandwidth of flat bands in magic-angle twisted bilayer graphene
Yi-Wen Liu, Ying Su, Xiao-Feng Zhou +10
The interplay between interlayer van der Waals interaction and intralayer lattice distortion can lead to structural reconstruction in slightly twisted bilayer graphene (TBG) with t…
Universal intrinsic higher-rank spin Hall effect
Junpeng Hou, Ying Su, Chuanwei Zhang
Spin Hall effect (SHE), a fundamental transport phenomenon with non-zero spin current but vanishing charge current, has important applications in spintronics for the electrical con…
Valley Polarization and Inversion in Strained Graphene via Pseudo-Landau Levels, Valley Splitting of Real Landau Levels and Confined States
Si-Yu Li, Ying Su, Ya-Ning Ren +1
It is quite easy to control spin polarization and spin direction of a system via magnetic fields. However, there is no such a direct and efficient way to manipulate valley pseudosp…
Chiral anomaly of Weyl magnons in stacked honeycomb ferromagnets
Ying Su, X. R. Wang
Chiral anomaly of Weyl magnons (WMs), featured by nontrivial band crossings at paired Weyl nodes (WNs) of opposite chirality, is investigated. It is shown that WMs can be realized…
Magnonic Weyl semimetal in pyrochlore ferromagnets
Ying Su, X. S. Wang, X. R. Wang
Topological states of matter have been a subject of intensive studies in recent years because of their exotic properties such as the topologically protected edge and surface states…
Topological Anderson Insulators in Systems without Time-Reversal Symmetry
Ying Su, Y. Avishai, X. R. Wang
Occurrence of topological Anderson insulator (TAI) in HgTe quantum well suggests that when time-reversal symmetry (TRS) is maintained, the pertinent topological phase transition, m…
A Band of Critical States in Anderson Localization at Strong Magnetic Field with Random Spin-Orbit Scattering
C. Wang, Ying Su, Y. Avishai +2
Anderson localization problem for non-interacting two-dimensional electron gas subject to strong magnetic field, disordered potential and spin-orbit coupling is studied numerically…
Creating Magnetic Fields in excess of 1000 T by Misoriented Stacking in a Graphene Bilayer
Wen-Yu He, Ying Su, Mudan Yang +1
It is well established that some kinds of lattice deformations in graphene monolayer, which change electron hopping in sublattice and affect in-plane motion of electrons, may induc…
