Higher-order Dirac fermions in three dimensions
Weikang Wu, Zhi-Ming Yu, Xiaoting Zhou +2
Relativistic massless Weyl and Dirac fermions exhibit the isotropic and linear dispersion relations to preserve the Poincaré symmetry, the most fundamental symmetry in high energy…
Two-dimensional honeycomb borophene oxide: A promising anode material offering super high capacity for Li/Na-ion batteries
Junping Hu, Chengyong Zhong, Weikang Wu +4
Rational design of novel two-dimensional (2D) electrode materials with high capacity is crucial for the further development of Li-ion and Na-ion batteries. Herein, based on first-p…
Composite Dirac Semimetal
Ziming Zhu, Zhi-Ming Yu, Weikang Wu +4
Weak topological insulators and Dirac semimetals are gapped and nodal phases with distinct topological properties, respectively. Here, we propose a novel topological phase that exh…
Circumventing the no-go theorem: A single Weyl point surrounded by nodal walls
Zhi-Ming Yu, Weikang Wu, Y. X. Zhao +1
Despite of a rapidly expanding inventory of possible crystalline Weyl semimetals, all of them are constrained by the Nielsen-Ninomiya no-go theorem, namely, that left- and right-ha…
Hourglass Weyl loops in two dimensions: Theory and material realization in monolayer GaTeI family
Weikang Wu, Yalong Jiao, Si Li +3
Nodal loops in two-dimensional (2D) systems are typically vulnerable against spin-orbit coupling (SOC). Here, we explore 2D systems with a type of doubly degenerate nodal loops tha…
Hexagonal supertetrahedral boron: A topological metal with multiple spin-orbit-free emergent fermions
Yan Gao, Weikang Wu, Peng-Jie Guo +4
We predict a new three-dimensional (3D) boron allotrope based on systematic first-principles electronic structure calculations. This allotrope can be derived by substituting each c…
