Title: Dirac nodal lines and large spin Hall effect in the $6 H$ -perovskite iridate ${Ba}_{3} {TiIr}_{2} O_{9}$

Abstract

Nodal line semimetals with symmetry protected band structure offer a platform for the investigation of a number of emerging quantum phenomena. Using first-principles calculation combined with symmetry analysis, we demonstrate that Ba₃TiIr₂O₉ hosts a Dirac nodal line (DNL) along the A-L direction of the Brillouin zone, protected by the glide reflection symmetry. In the presence of the spin-orbit coupling, even though the DNL along the A-L direction is protected, DNLs along other directions as well as multiple nodal loops present in the system gap out. The gapped out Dirac nodal loops act as a source of spin Berry curvature, resulting in a large spin Hall conductivity (≈300 $$^h_{\bar{e}}$$ Ω^–1 cm^–1). This suggests the possible application of the material as a spin current detector.

Strong spin-orbit coupling and Dirac nodal lines in the three-dimensional electronic structure of metallic rutile ${IrO}_{2}$

Journal Article Xu, X. ; Jiang, J. ; Shi, W. J. ; ... - Physical Review B

Using high-resolution angle-resolved photoemission spectroscopy and ab initio calculation, we have studied the bulk and surface electronic structure of metallic rutile 5d transition metal oxide IrO₂ that harbors both edge and corner sharing Ir-O octahedrons. We observe strong modulation of the band structure by spin-orbit coupling (SOC). The measured band structure is well reproduced by our ab initio calculation without band renormalization, suggesting the absence of the SOC-enhanced correlation effect in IrO₂. In accordance with the calculation, we visualize two types of Dirac nodal lines (DNLs) protected by mirror symmetry and nonsymmorphic crystal symmetry, respectively. SOC gaps the first typemore »« less

Correlation Effects and Hidden Spin-Orbit Entangled Electronic Order in Parent and Electron-Doped Iridates ${Sr}_{2} {IrO}_{4}$

Journal Article Zhou, Sen ; Jiang, Kun ; Chen, Hua ; ... - Physical Review. X

Analogs of the high-T_c cuprates have been long sought after in transition metal oxides. Because of the strong spin-orbit coupling, the 5d perovskite iridates Sr₂IrO₄ exhibit a low-energy electronic structure remarkably similar to the cuprates. Whether a superconducting state exists as in the cuprates requires understanding the correlated spin-orbit entangled electronic states. Recent experiments discovered hidden order in the parent and electron-doped iridates, some with striking analogies to the cuprates, including Fermi surface pockets, Fermi arcs, and pseudogap. Here, we study the correlation and disorder effects in a five-orbital model derived from the band theory. We find that the experimentalmore »« less

Topological Hourglass Dirac Semimetal in the Nonpolar Phase of ${Ag}_{2} {BiO}_{3}$

Journal Article Singh, Bahadur ; Ghosh, Barun ; Su, Chenliang ; ... - Physical Review Letters

Materials with tunable charge and lattice degrees of freedom provide excellent platforms for investigating multiple phases that can be controlled via external stimuli. We show how the charge-ordered ferroelectric oxide Ag₂BiO₃, which has been realized experimentally, presents a unique exemplar of a metal-insulator transition under an external electric field. Our first-principles calculations, combined with a symmetry analysis, reveal the presence of a nearly ideal hourglass-Dirac-semimetal state in the nonpolar structure of Ag₂BiO₃. The low-energy band structure consists of two hourglasslike nodal lines located on two mutually orthogonal glide-mirror planes in the absence of spin-orbit coupling (SOC) effects. These lines cross at a common point and form an interlinked chainlike structure, which extends beyond the first Brillouin zone. Inclusion of the SOC opens a small gap in the nodal lines and results in two symmetry-enforced hourglasslike Dirac points on themore »« less

Phononic Helical Nodal Lines with $PT$ Protection in ${MoB}_{2}$

Journal Article Zhang, T. T. ; Miao, H. ; Wang, Q. ; ... - Physical Review Letters

While condensed matter systems host both fermionic and bosonic quasiparticles, reliably predicting and empirically verifying topological states is only mature for Fermionic electronic structures, leaving topological Bosonic excitations sporadically explored. This is unfortunate, as Bosonic systems such as phonons offer the opportunity to assess spinless band structures where nodal lines can be realized without invoking special additional symetries to protect against spin-orbit coupling. Here we combine first-principles calculations and meV-resolution inelastic x-ray scattering to demonstrate the first realization of parity-time reversal symmetry protected helical nodal lines in the phonon spectrum of MoB₂. This structure is unique to phononic systems asmore »« less
