Phononic Weyl Nodal Straight Lines in High-Temperature Superconductor MgB
Qing Xie, Jiangxu Li, Min Liu +4
Based on first-principles calculations, we predict that the superconducting MgB with a AlB-type centrosymmetric lattice host the so-called phononic topological Weyl nodal l…
Coexisted Three-component Bosons and Two-component Weyl Bosons in TiS, ZrSe and HfTe
J. X. Li, Q. Xie, S. Ullah +5
In analogy to various fermions of electrons in topological semimetals, topological mechanical states with two type of bosons, Dirac and Weyl bosons, were reported in some macroscop…
Three-component bosons in TiS, ZrSe and HfTe
Sami Ullah, Jiangxu Li, Ronghan Li +5
Topological semimetals with several types of three-dimensional (3D) fermion of electrons, such as Dirac fermions, Weyl fermions, Dirac nodal lines and triply degenerate nodal point…
Topological nodal line states and a potential catalyst of hydrogen evolution in the TiSi family
Jiangxu Li, Hui Ma, Shaobo Feng +6
Topological nodal line (DNL) semimetals, formed by a closed loop of the inverted bands in the bulk, result in the nearly flat drumhead-like surface states with a high electronic de…
Prediction of new Group IV-V-VI monolayer semiconductors based on first principle calculation
Qingxing Xie, Junhui Yuan, Niannian Yu +2
Two-dimension (2D) semiconductor materials have attracted much attention and research interest for their novel properties suitable for electronic and optoelectronic applications. I…
