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…
Temperature Dependent Electronic Structure in a Higher Order Topological Insulator Candidate EuInAs
Sabin Regmi, Md Mofazzel Hosen, Barun Ghosh +12
The higher order topological insulator (HOTI) has enticed enormous research interests owing to its novelty in supporting gapless states along the hinges of the crystal. Despite sev…
Realization of an intrinsic, ferromagnetic topological state in MnBi8Te13
Chaowei Hu, Lei Ding, Kyle N. Gordon +18
The interplay between topology and magnetism is essential for realizing novel topological states including the axion insulator, the magnetic Weyl semimetal, etc. An intrinsically f…
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…
