Prediction of three-fold fermions in a nearly-ideal Dirac semimetal BaAgAs
Sougata Mardanya, Bahadur Singh, Shin-Ming Huang +5
Materials with triply-degenerate nodal points in their low-energy electronic spectrum produce crystalline-symmetry-enforced three-fold fermions, which conceptually lie between the…
Spin-dependent scattering induced negative magnetoresistance in topological insulator Bi2Te3 nanowires
Biplab Bhattacharyya, Bahadur Singh, R. P. Aloysius +7
Studies of negative magnetoresistance in novel materials have recently been in the forefront of spintronic research. Here, we report an experimental observation of the temperature…
Saddle-point von Hove singularity and dual topological insulator state in PtHgSe
Barun Ghosh, Sougata Mardanya, Bahadur Singh +7
Saddle-point van Hove singularities in the topological surface states are interesting because they can provide a new pathway for accessing exotic correlated phenomena in topologica…
Topological Hourglass Dirac Semimetal in the Nonpolar Phase of AgBiO
Bahadur Singh, Barun Ghosh, Chenliang Su +3
Materials with tunable charge and lattice degrees of freedom provide excellent platforms for investigating multiple phases that can be controlled via external stimuli. We show how…
Tunable double-Weyl Fermion semimetal state in the SrSi materials class
Bahadur Singh, Guoqing Chang, Tay-Rong Chang +5
We discuss first-principles topological electronic structure of noncentrosymmetric SrSi materials class based on the hybrid exchange-correlation functional. Topological phase d…
Starfruit-like nodal semimetal to Dirac and Weyl semimetal state in CaAuAs
Bahadur Singh, Sougata Mardanya, Chenliang Su +3
Band-crossings occurring on a mirror plane are compelled to form a nodal loop in the momentum space without spin-orbit coupling (SOC). In the presence of other equivalent mirror pl…
