| 1 | Summary of World Military Situation in 2018: the Changing Peace Force显示文摘The year 2018 is one of uncertainty.In this year,the world power balance accelerated its evolution,the competition and game-play among major powers became increasingly fierce,and the relations between major powers were sometimes tense and sometimes relaxed;in this year,local conflicts sometimes found tense development and became calm later;in this year,international terrorism,like'a hundred-feet bug,dead but not rigid yet',even resurged in some regions.Faced with the rapidly changing world pattern,many countries adopted different countermeasures,some of which were positive and in conformity with the trend;some panicked and bewildered,and still some even moving against the trend. | Chen Hanghui | 2019 | Peace2019，，1： | 0 |
| 2 | Emergent topological states via digital(001)oxide superlattices显示文摘Oxide heterostructures exhibit many intriguing properties.Here we provide design principles for inducing multiple topological states in(001)(AMO_(3))_(1)/(AM′O_(3))_(1)oxide superlattices.Aided by first-principles calculations and model analysis,we show that a(SrMO_(3))_(1)/(SrM′O_(3))_(1)superlattice(M=Nb,Ta and M′=Rh,Ir)is a strong topological insulator with Z_(2)index(1;001).More remarkably,a(SrMoO_(3))1/(SrIrO_(3))_(1)superlattice exhibits multiple coexisting topological insulator(TI)and topological Dirac semi-metal(TDS)states.The TDS state has a pair of type-II Dirac points near the Fermi level and symmetry-protected Dirac node lines.The surface TDS Dirac cone is sandwiched by two surface TI Dirac cones in the energy-momentum space.The non-trivial topological properties arise from the band inversion between d orbitals of two dissimilar transition metal atoms and a particular parity property of(001)superlattice geometry.Our work demonstrates how to induce non-trivial topological states in(001)perovskite oxide heterostructures by rational design. | Zhiwei Liu Hongquan Liu Jiaji Ma Xiaoxuan Wang Gang Li Hanghui Chen | 2022 | npj Computational Materials2022，，1： | 0 |
