Magnon hybridization in ferrimagnetic heterostructures
Song Li, Ka Shen, Ke Xia
We study magnon hybridization in a ferrimagnetic heterostructure consisting of ultrathin gadolinium iron garnet and yttrium iron garnet layers and show the localized and extended s…
Recent progress in antiferromagnetic dynamics
H. Y. Yuan, Zhe Yuan, Rembert A. Duine +1
Spintronics, since its inception, has mainly focused on ferromagnetic materials for manipulating the spin degree of freedom in addition to the charge degree of freedom, whereas muc…
Spin-orbit coupling and linear crossings of dipolar magnons in van der Waals antiferromagnets
Jie Liu, Lin Wang, Ka Shen
A magnon spin-orbit coupling, induced by the dipole-dipole interaction, is derived in monoclinic-stacked bilayer honeycomb spin lattice with perpendicular magnetic anisotropy and a…
Nonequilibrium phases and phase transitions of the XY-model
Tharnier O. Puel, Stefano Chesi, Stefan Kirchner +1
We obtain the steady-state phase diagram of a transverse field XY spin chain coupled at its ends to magnetic reservoirs held at different magnetic potentials. In the long-time limi…
Deep-ultraviolet Layered Oxide B2S2O9 with Strong and Robust Second Harmonic Generation
Lei Kang, Xiaomeng Liu, Zheshuai Lin +1
Two-dimensional (2D) layered semiconductors with both ultrawide bandgap and strong second harmonic generation (SHG) are essential for expanding the nonlinear optical (NLO) applicat…
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…
Valley-selective Floquet Chern Flat Bands in Twisted Multilayer Graphene
Ming Lu, Jiang Zeng, Haiwen Liu +2
We show that Floquet engineering with circularly polarized light (CPL) can selectively split the valley degeneracy of a twisted multilayer graphene (TMG), and thus generate a contr…
Irrational Non-Abelian Statistics for Non-Hermitian Generalization of Majorana Zero Modes
Xiao-Ming Zhao, Cui-Xian Guo, Meng-Lei Yang +3
In condensed matter physics, non-Abelian statistics for Majorana zero modes (or Majorana Fermions) is very important, really exotic, and completely robust. The race for searching M…
Transport study of the wormhole effect in three-dimensional topological insulators
Ming Gong, Ming Lu, Haiwen Liu +3
Inside a three-dimensional strong topological insulator, a tube with magnetic flux carries a pair of protected one-dimensional linear fermionic modes. This phenomenon is kno…
Dipolar spin waves in uniaxial easy-axis antiferromagnets: A natural topological nodal-line semimetal
Jie Liu, Lin Wang, Ka Shen
The existence of the magnetostatic surface spin waves in ferromagnets, known as Damon-Eshbach mode, was recently demonstrated to originate from the topology of the dipole-dipole in…
Non-Hermitian coherent coupling of nanomagnets by exchange spin waves
Hanchen Wang, Jilei Chen, Tao Yu +16
Non-Hermitian physics has recently attracted much attention in optics and photonics. Less explored is non-Hermitian magnonics that provides opportunities to take advantage of the i…
Pseudospin-electric coupling for holes beyond the envelope-function approximation
Pericles Philippopoulos, Stefano Chesi, Dimitrie Culcer +1
In the envelope-function approximation, interband transitions produced by electric fields are neglected. However, electric fields may lead to a spatially local (-independent) co…
State-dependent Topological Invariants and Anomalous Bulk-Boundary Correspondence in non-Hermitian Topological Systems
Xiao-Ran Wang, Cui-Xian Guo, Su-Peng Kou
The breakdown of the bulk-boundary correspondence in non-Hermitian (NH) topological systems is an open, controversial issue. In this paper, to resolve this issue, we ask the follow…

It was known that for non-Hermitian topological systems due to the non-Hermitian skin effect, the bulk-edge correspondence is broken down. In this paper, by using one-dimensional S…
3D Quantum Hall Effect Manipulated by Chiral Landau Levels in Weyl Semimetals
Hailong Li, Haiwen Liu, Hua Jiang +1
We investigate the 3D quantum Hall effect in Weyl semimetals and elucidate a global picture of the edge states. The edge states hosting 3D quantum Hall effect are combinations of F…
Superradiant-like dynamics by electron shuttling on a nuclear-spin island
Yi-Nan Fang, Ying-Dan Wang, Rosario Fazio +1
We investigate superradiant-like dynamics of the nuclear-spin bath in a single-electron quantum dot, by considering electrons cyclically shuttling on/off an isotopically enriched `…
Nanoscale Probing of Broken-Symmetry States in Graphene Induced by Individual Atomic Impurities
Yu Zhang, Qi-Qi Guo, Si-Yu Li +1
Inherent symmetries of a system lead to multiple degeneracies of its energy spectra. Introducing individual atomic impurities can locally break these symmetries, which is expected…
