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…
Anomalous and Topological Hall effect in Cu doped Sb2Te3 Topological Insulator
Abhishek Singh, Vinod K Gangwar, Prashant Shahi +6
The magneto-transport and magnetization measurements of Sb1.90Cu0.10Te3 were performed at different temperatures and different fields. Magneto-transport measurement at high field i…
Pressure-Induced Topological Phase Transitions in CdGeSb and CdSnSb
Rinkle Juneja, Ravindra Shinde, Abhishek K. Singh
Topological quantum phase transitions (TQPTs) in a material induced by external perturbations are often characterized by band touching points in the Brillouin zone. The low-energy…
Multiple Triple-Point Fermions in Heusler Compounds
Ranjan Kumar Barik, Ravindra Shinde, Abhishek K. Singh
Using the density functional theoretical calculations, we report a new set of topological semimetals XYZ (X = \{Cu, Rh, Pd, Ag, Au, Hg\}, Y = \{Li, Na, Sc, Zn, Y, Zr, Hf, La,…
