Abstract: Topological semimetals, such as topological nodal point semimetals (TNPSs) and topological nodal line state semimetals (TNLSs), featuring zero-dimensional (0D) and one-dimensional (1D) topological elements (TEs), respectively, have attracted widespread attention in recent years. In this… read more here.

DOI: 10.1103/physrevx.8.031044
Abstract: The topological nodal-line semimetal state, serving as a fertile ground for various topological quantum phases, where a topological insulator, Dirac semimetal, or Weyl semimetal can be realized when the certain protecting symmetry is broken, has… read more here.
