Doping Induced Second Harmonic Generation in Centrosymmetric Graphene from Quadrupole Response
Yu Zhang, Di Huang, Yuwei Shan +8
For centrosymmetric materials such as monolayer graphene, no optical second harmonic generation (SHG) is generally expected because it is forbidden under the electric-dipole approx…
Possible pairing symmetry in the FeSe-based superconductors determined by quasiparticle interference
Yi Gao, Yuting Wang, Tao Zhou +2
We study the momentum-integrated quasiparticle interference (QPI) in the FeSe-based superconductors. This method was recently proposed theoretically and has been applied to determi…
Schwinger effect of a relativistic boson entangled with a qubit
Yujie Li, Yu Shi
We use the concept of quantum entanglement to analyze the Schwinger effect on an entangled state of a qubit and a bosonic mode coupled with the electric field. As a consequence of…
Visualization of higher-order topological insulating phases in two-dimensional dielectric photonic crystals
Bi-Ye Xie, Guang-Xu Su, Hong-Fei Wang +6
The studies of topological phases of matter have been extended from condensed matter physics to photonic systems, resulting in fascinating designs of robust photonic devices. Recen…
Comparative study of vortex dynamics in CaKFe4As4 and Ba0.6K0.4Fe2As2 single crystals
Wang Cheng, Hai Lin, Bing Shen +1
We investigate the vortex dynamics in two typical hole doped iron based superconductors CaKFeAs (CaK1144) and BaKFeAs (BaK122) with similar supercon…
Ferromagnetic van der Waals crystal VI3
Shangjie Tian, Jian-Feng Zhang, Chenghe Li +5
We report structural, physical properties and electronic structure of van der Waals (vdW) crystal VI3. Detailed analysis reveals that VI3 exhibits a structural transition from mono…
