The present work solves Maxwell equations and demonstrates the new photonic topology by revealing pseudospin-resolved Berry curvatures of photonic bands and helical edge states characterized by Poynting vectors.Expand

It is proposed that the cubic antiperovskite material Cu3PdN can host a three-dimensional (3D) topological node-line semimetal state when spin-orbit coupling (SOC) is ignored, which is protected by the coexistence of time-reversal and inversion symmetry.Expand

Over a long period of exploration, the successful observation of quantized version of anomalous Hall effect (AHE) in thin film of magnetically doped topological insulator (TI) completed a quantum… Expand

An effective theory containing an analogue of the Wess-Zumino-Witten term is derived, which generates quantum phases related to AFM monopoles with VBS cores, and reproduces Haldane's hedgehog Berry phases.Expand

A spin-resolved STM/STS technique is expected to be able to provide phase-sensitive evidence for a MBS in the vortex core of a topological superconductor.Expand

A time-reversal-symmetry-broken (TRSB) superconductivity can be induced by sign-reversed intercomponent couplings in superconductors with three components or above. Here we derive stability… Expand

Exact series solutions for two electrons in one-dimensional nanorings have been obtained by expanding the Coulomb potential into power series and solving the corresponding equations in different… Expand

Half-metallic antiferromagnets as a subclass of half-metals are characterized further by totally compensated spin moments in a unit cell, and have the advantage of being able to generate fully spin-polarized current while exhibiting zero macroscopic magnetization.Expand

The nontrivial topology is characterized by the index associated with a pseudo time-reversal symmetry emerging from the C6 symmetry of the hopping texture, where the angular momentum of orbitals accommodated on the hexagonal “artificial atoms” behaves as the pseudospin.Expand

We propose a scheme of band engineering by means of staggered electric potential, antiferromagnetic exchange field and intrinsic spin–orbit coupling for electrons on a honeycomb lattice. With fine… Expand
