recommendations! Published in 2017 at "Nature Physics"

DOI: 10.1038/nphys4306

Abstract: The topological properties of fermions arise from their low-energy Dirac-like band dispersion and associated chirality. Initially confined to points, extensions of the Dirac dispersion to lines, and even loops, have now been uncovered, and semimetals… read more here.

DOI: 10.1088/1361-6528/ac1cbe

Abstract: By means of quotient-graph associated crystal prediction method, a new graphyne allotrope with unique Dirac nodal grid state is reported in this work. It is named as 191-E24Y24-1 according to its hexagonal lattice (with P6/mmm… read more here.

DOI: 10.1103/physrevb.95.075426

Abstract: We study the unique physical properties of topological nodal-loop semimetals protected by the coexistence of time-reversal and inversion symmetries with negligible spin-orbit coupling. We argue that strong correlation effects occur at the surface of such… read more here.

DOI: 10.1103/physrevb.97.235150

Abstract: Topological metals and semimetals are new states of matter which are attracting great interest in current research. Here, based on first-principles calculations and symmetry analysis, we propose that the family of titanium-based compounds ${\mathrm{Ti}}_{3}X$ ($X$=Al,… read more here.

DOI: 10.3389/fchem.2025.1544147

Abstract: The investigation of two-dimensional materials exhibiting half-metallicity and topological features has become a rapidly growing area of interest, driven by their immense potential in nanoscale spintronics and quantum electronics. In this work, we present a… read more here.
