Abstract: Using ab initio calculations based on density-functional theory and effective model analysis, we propose that the trigonal YH3 (Space Group: P$$\bar{{\bf{3}}}$$3¯c1) at ambient pressure is a node-line semimetal when spin-orbit coupling (SOC) is ignored. This… read more here.

Abstract: Two-dimensional (2D) topological insulators (TIs) have attracted tremendous research interest from both theoretical and experimental fields in recent years. However, it is much less investigated in realizing node line (NL) semimetals in 2D materials.Combining first-principles… read more here.
