Chiral Antiferromagnetism from Momentum-Space Resonance in a 2D Semiconductor
R. Okuma, T. Ikenobe, Y. Fujisawa +28
Understanding the principles governing the emergence of chiral quantum phases is a fundamental challenge, not only for uncovering new mechanisms of quantum-state formation but also…
Electronic Transport Studies of Ag-doped Bi2Se3 Topological Insulator
Shailja Sharma, Shiv Kumar, Amit Kumar +2
The structural, magnetotransport, and angle-resolved photoemission spectroscopy (ARPES) of Ag-doped Bi2Se3 single crystals are presented. Temperature dependent resistivity exhibits…
Realization of Practical Eightfold Fermions and Fourfold van Hove Singularity in TaCoTe
Hongtao Rong, Zhenqiao Huang, Xin Zhang +20
Space groups describing the symmetry of lattice structure allow the emergence of fermionic quasiparticles with various degeneracy in the band structure. Theoretical efforts have pr…
Magneto-Transport and High-Resolution Angle-Resolved Photoelectron Spectroscopy Studies of Palladium Doped BiTe
Shailja Sharma, Shiv Kumar, Girish C. Tewari +5
We have performed magneto-transport and high-resolution angle-resolved photoelectron spectroscopy (ARPES) measurements on palladium (Pd) doped topological insulator PdBi$_{2}…
Behavior of gapped and ungapped Dirac cones in an antiferromagnetic topological metal, SmBi
Anup Pradhan Sakhya, Shiv Kumar, Arindam Pramanik +10
We studied the behavior of nontrivial Dirac fermion states in an antiferromagnetic metal SmBi using angle-resolved photoemission spectroscopy (ARPES). The experimental results exhi…
Orbital Complexity in Intrinsic Magnetic Topological Insulators MnBiTe and MnBiTe
R. C. Vidal, H. Bentmann, J. I. Facio +16
Using angle-resolved photoelectron spectroscopy (ARPES), we investigate the surface electronic structure of the magnetic van der Waals compounds MnBiTe and MnBiTe$_{10}…
