Anisotropic gapping of topological Weyl rings in the charge-density-wave superconductor In TaSe2 [PDF]

Science Bulletin, 2021
Topological materials and topological phases have recently become a hot topic in condensed matter physics. In this work, we report a topological nodal-line semimetal InxTaSe2, in the presence of both charge density wave (CDW) and superconductivity. In the x = 0.58 samples, the 2 * /3 commensurate CDW (CCDW) and the 2 * 2 CCDW are observed below 116 K ...

Electron Pumping and Spectral Density Dynamics in Energy-Gapped Topological Chains [PDF]

Applied Sciences, 2021
Electron pumping through energy-gapped systems is restricted for vanishing local density of states at the Fermi level. In this paper, we propose a topological Su–Schrieffer–Heeger (SSH) chain between unbiased leads as an effective electron pump. We analyze the electron transport properties of topologically trivial and nontrivial systems in the presence

Revealing a charge-density-wave gap in the predicted weak topological insulator HoSbTe [PDF]

Physical Review B, 2022
HoSbTe was predicted to be a weak topological insulator, whose spin-orbit coupling (SOC) gaps are reported to be as large as hundreds of meV. Utilizing infrared spectroscopy, we find that the compound is of metallic nature from 350 K down to 10 K. Particularly, both of its itinerant carrier density and scattering rate are demonstrated to decrease with ...

Superdense Hexagonal BP and AlP with Quartz Topology: Crystal Chemistry and DFT Study

Crystals, 2023
The superdense hexagonal phosphides BP and AlP, whose structures are formed by distorted tetrahedra and characterized by quartz-derived (qtz) topology, were predicted from crystal chemistry and first principles as potential high-pressure phases.

Ultrahigh-Density Superhard Hexagonal BN and SiC with Quartz Topology from Crystal Chemistry and First Principles

Crystals, 2023
Based on superdense C6 with a quartz (qtz) topology, new ultrahigh-density hexagonal binary phases, qtz BN and qtz SiC, were identified via full geometry structure relaxations and ground state energies using calculations based on the quantum density ...

Aspects of symmetry and topology in the charge density wave phase of 1T–TiSe2

New Journal of Physics, 2021
The charge density wave (CDW) in 1 T –TiSe _2 harbors a nontrivial symmetry configuration. It is important to understand this underlying symmetry both for gaining a handle on the mechanism of CDW formation and for probing the CDW experimentally.

Muon spin relaxation study of the layered kagome superconductor CsV_{3}Sb_{5}

Physical Review Research, 2022
The Z_{2} topological metals RV_{3}Sb_{5} (R = K, Rb, Cs) with a layered kagome structure provide a unique opportunity to investigate the interplay between charge order, superconductivity, and topology. Here, we report muon-spin relaxation/rotation (μSR)
