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…
Aspects of symmetry and topology in the charge density wave phase of 1T-TiSe2
Shin-Ming Huang, Su-Yang Xu, Bahadur Singh +5
The charge density wave (CDW) in 1T-TiSe2 accompanied by the periodic lattice distortion has a nontrivial symmetry configuration. The symmetry is important as an indication of the…
Unexplored photoluminescence from bulk and mechanically exfoliated few layers of Bi2Te3
Bipin Kumar Gupta, Rabia Sultana, Satbir Singh +8
We report the exotic photoluminescence (PL) behaviour of 3D topological insulator Bi2Te3 single crystals grown by customized self-flux method and mechanically exfoliated few layers…
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…
