Topological nodal line semimetals, a novel quantum state of materials, possess topologically nontrivial valence and conduction bands that touch at a line near the Fermi level. The exotic band structure can lead to various novel properties, such as long-range Coulomb interaction and flat Landau levels. Recently, topological nodal lines have been observed in several bulk materials, such as PtSn<sub>4</sub>, ZrSiS, TlTaSe<sub>2</sub> and PbTaSe<sub>2</sub>. However, in two-dimensional materials, ex ...[more]
