Topological crystalline insulator state with type-II Dirac fermions in transition metal dipnictides
Baokai Wang, Bahadur Singh, Barun Ghosh +8
The interplay between topology and crystalline symmetries in materials can lead to a variety of topological crystalline insulator (TCI) states. Despite significant effort towards t…
Low-energy type-II Dirac fermions and spin-polarized topological surface states in transition-metal dichalcogenide NiTe
Barun Ghosh, Debashis Mondal, Chia-Nung Kuo +6
Using spin- and angle- resolved photoemission spectroscopy (spin-ARPES) together with calculations, we demonstrate the existence of a type-II Dirac semimetal stat…
Intrinsic magnetism in monolayer transition metal trihalides: a comparative study
Shalini Tomar, Barun Ghosh, Sougata Mardanya +5
Two dimensional magnetic materials, with tunable electronic properties could lead to new spintronic, magnetic and magneto-optic applications. Here, we explore intrinsic magnetic or…
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…
