Spectroscopic evidence for electron-boson coupling in electron-doped SrIrO
Yong Hu, Xiang Chen, S. -T. Peng +15
The pseudogap, d-wave superconductivity and electron-boson coupling are three intertwined key ingredients in the phase diagram of the cuprates. SrIrO is a 5d-electron count…
Identification of ferrimagnetic orbitals preventing spinel degradation by charge ordering in LiMnO
Hasnain Hafiz, Kosuke Suzuki, Bernardo Barbiellini +10
Spinel LiMnO is a key cathode material that is used extensively in commercial Li-ion batteries. A challenge with this material has been that the capacity of the battery…
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…
Transition from Intrinsic to Extrinsic Anomalous Hall Effect in the Ferromagnetic Weyl Semimetal PrAlGeSi
Hung-Yu Yang, Bahadur Singh, Baozhu Lu +10
Recent reports of a large anomalous Hall effect (AHE) in ferromagnetic Weyl semimetals (FM WSM) have led to a resurgence of interest in this enigmatic phenomenon. However, due to a…
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…
