Evidence for Unconventional Superconductivity and Nontrivial Topology in PdTe
Ramakanta Chapai, P. V. Sreenivasa Reddy, Lingyi Xing +4
PdTe is a superconductor with Tc ~4.25 K. Recently, evidence for bulk-nodal and surface-nodeless gap features has been reported in PdTe [Yang et al., Phys. Rev. Lett. 130, 046402 (…
Observation of Gapped Topological Surface States and Isolated Surface Resonances in PdTe Ultrathin Films
Jacob Cook, Sougata Mardanya, Qiangsheng Lu +7
The superconductor PdTe is known to host bulk Dirac bands and topological surface states. The coexistence of superconductivity and topological surface states makes PdTe a p…
Magnetic dilution effect and topological phase transitions in (MnPb)BiTe
Tiema Qian, Yueh-Ting Yao, Chaowei Hu +5
As the first intrinsic antiferromagnetic (AFM) topological insulator (TI), MnBiTe has provided a material platform to realize various emergent phenomena arising from the in…
Discovery of charge order and corresponding edge state in kagome magnet FeGe
Jia-Xin Yin, Yu-Xiao Jiang, Xiaokun Teng +21
Kagome materials often host exotic quantum phases, including spin liquids, Chern gap, charge order, and superconductivity. Existing scanning microscopy studies of the kagome charge…
Lifshitz transition and van Hove singularity in a Topological Dirac Semimetal
Su-Yang Xu, Chang Liu, I. Belopolski +20
A topological Dirac semimetal is a novel state of quantum matter which has recently attracted much attention as an apparent 3D version of graphene. In this paper, we report critica…
Non-Kondo-like Electronic Structure in the Correlated Rare-Earth Hexaboride YbB
Madhab Neupane, Su-Yang Xu, Nasser Alidoust +11
We present angle-resolved photoemission studies on the rare-earth hexaboride YbB, which has recently been predicted to be a topological Kondo insulator. Our data do not agree w…
Observation of a bulk 3D Dirac multiplet, Lifshitz transition, and nestled spin states in Na3Bi
Su-Yang Xu, Chang Liu, S. K. Kushwaha +20
Symmetry or topology protected Dirac fermion states in two and three dimensions constitute novel quantum systems that exhibit exotic physical phenomena. However, none of the studie…
