Evidence of topological insulator state in the semimetal LaBi
R. Lou, B. -B. Fu, Q. N. Xu +17
By employing angle-resolved photoemission spectroscopy combined with first-principles calculations, we performed a systematic investigation on the electronic structure of LaBi, whi…
Spin correlations and colossal magnetoresistance in HgCrSe
Chaojing Lin, Changjiang Yi, Youguo Shi +4
This study aims to unravel the mechanism of colossal magnetoresistance (CMR) observed in n-type HgCrSe, in which low-density conduction electrons are exchange-coupled to a…
Raman scattering in transition metal dichalcogenides MTe2 (M = Mo, W)
Xiaoli Ma, Pengjie Guo, Changjing Yi +10
We performed comparable polarized Raman scattering studies of MoTe2 and WTe2. By rotating crystals to tune the angle between the principal axis of the crystals and the polarization…
Heavy fermion behavior in the quasi-one-dimensional Kondo lattice CeCo2Ga8
Le Wang, Zhaoming Fu, Jianping Sun +13
Dimensionality plays an essential role in determining the anomalous non-Fermi liquid properties in heavy fermion systems. So far most heavy fermion compounds are quasi-two-dimensio…
Spin Texture in Type-II Weyl Semimetal WTe2
Baojie Feng, Yang-Hao Chan, Ya Feng +15
We determine the band structure and spin texture of WTe2 by spin- and angle-resolved photoemission spectroscopy (SARPES). With the support of first-principles calculations, we reve…
Experimental Discovery of the First Nonsymmorphic Topological Insulator KHgSb
J. -Z. Ma, C. -J. Yi, B. Q. Lv +11
Topological insulators (TIs) host novel states of quantum matter, distinguished from trivial insulators by the presence of nontrivial conducting boundary states connecting the vale…
Spectroscopic Evidence of Type II Weyl Semimetal State in WTe2
Chenlu Wang, Yan Zhang, Jianwei Huang +29
Quantum topological materials, exemplified by topological insulators, three-dimensional Dirac semimetals and Weyl semimetals, have attracted much attention recently because of thei…
Anisotropic transport and optical spectroscopy study on antiferromagentic triangular lattice EuCd_2As_2: an interplay between magnetism and charge transport properties
H. P. Wang, D. S. Wu, Y. G. Shi +1
We present anisotropic transport and optical spectroscopy studies on EuCd_2As_2. The measurements reveal that EuCd_2As_2 is a low carrier density semimetal with moderate anisotropi…
Giant semiclassical magnetoresistance in high mobility TaAs2 semimetal
Desheng Wu, Jian Liao, Wei Yi +8
We report the observation of colossal positive magnetoresistance (MR) in single crystalline, high mobility TaAs2 semimetal. The excellent fit of MR by a single quadratic function o…
