Scheme for Achieving a Topological Photonic Crystal by Using Dielectric Material.
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.
Topological Node-Line Semimetal and Dirac Semimetal State in Antiperovskite Cu3PdN.
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.
Quantum anomalous Hall effect and related topological electronic states
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
Many-body spin Berry phases emerging from the pi-flux state: competition between antiferromagnetism and the valence-bond-solid state.
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.
Evolution of Density of States and a Spin-Resolved Checkerboard-Type Pattern Associated with the Majorana Bound State.
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.
Stability and Josephson effect of time-reversal-symmetry-broken multicomponent superconductivity induced by frustrated intercomponent coupling
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
Two electrons in one-dimensional nanorings: Exact solutions and interaction energies
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

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.
Topological Properties of Electrons in Honeycomb Lattice with Detuned Hopping Energy
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.
Electrically tunable topological state in [111] perovskite materials with an antiferromagnetic exchange field
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
