Topological phases in hydrogenated gallenene and in its group elements
Ranjan Kumar Barik, Ritesh Kumar, Abhishek K. Singh
Nontrivial topology of Dirac (DSMs), Weyl (WSMs) and nodal line semimetals (NLSMs) are delineated by the novel band crossings near the Fermi level in the bulk and the appearance of…

Topological semimetals with nodal-rings and nexus fermions
Mighfar Imam, Ranjan Kumar Barik, Rinkle Juneja +2
Based on the first-principles study, we report a new set of topological semimetals (TiS, TiSe, TiTe, HfS, HfSe, HfTe and ZrS) which show the co-existence of a nodal-ring and triply…
