Dirac polaron dynamics in the correlated semimetal of perovskite CaIrO3
• Physics
• 2021
We have investigated the charge dynamics of the correlated Dirac semimetallic perovskite ${\mathrm{CaIrO}}_{3}$ by infrared spectroscopy. The optical conductivity spectra show theExpand
Topological crystalline metal in orthorhombic perovskite iridates.
• Materials Science, Medicine
• Nature communications
• 2015
It is predicted that orthorhombic perovskite iridates realize a new class of metals dubbed topological crystalline metals, which support zero-energy surface states protected by certain lattice symmetry, which can be probed by photoemission and tunnelling experiments. Expand
Experimental progress on layered topological semimetals
We review recent experimental progresses on layered topological materials, mainly focusing on transitional metal dichalcogenides with various lattice types including 1T, Td and 1T' structural phases.Expand
Dirac and Weyl Semimetal in XYBi (X = Ba, Eu; Y = Cu, Ag and Au)
• Materials Science, Physics
• Scientific reports
• 2015
Combining first-principles calculations and effective model analysis, it is predicted that nonmagnetic compounds BaYBi (Y = Au, Ag and Cu) are Dirac semimetals and that partially substitute Eu ions by Ba ions will realize the Weyl semimetal. Expand
Deep Insight Into the Electronic Structure of Ternary Topological Insulators: A Comparative Study of PbBi 4 Te 7 and PbBi 6 Te 10
By means of angle-resolved photoemission spectroscopy measurements, the electronic band structure of the three-dimensional PbBi4Te7 and PbBi6Te10 topological insulators is compared. The measurementsExpand
Topological Magnons with Nodal-Line and Triple-Point Degeneracies: Implications for Thermal Hall Effect in Pyrochlore Iridates.
• Physics, Medicine
• Physical review letters
• 2020
Three distinct regimes of magnon band topology are found, as a function of the ratio of Dzyaloshinskii-Moriya interaction to the antiferromagnetic exchange, in AIAO systems. Expand

• Chemistry of materials : a publication of the American Chemical Society
• 2020
This study experimentally demonstrates that the topological properties of the ferromagnetic kagomé compound Co3Sn2S2 are preserved upon Ni substitution, and systematically varies the Ni content in single crystals and study their magnetic and anomalous transport properties. Expand
Spontaneous Hall effect in the Weyl semimetal candidate of all-in all-out pyrochlore iridate
• Medicine, Physics
• Nature Communications
• 2018
Experimental observations are presented proving that the pyrochlore iridate, when electronically tuned, can be a topological Weyl semimetal as predicted by recent theories, and the manifestation of the salient Hall response provides one important example of topological states, which promotes a better understanding of WeylSemimetal and indicates the new research direction for the topological-materials design.
