, 2017 We match analytic results to numerical calculations to provide a detailed picture of the metal-insulator and topological transitions found in density functional plus cluster dynamical mean-field calculations of pyrochlore iridates.

Spectroscopic Evidence of Edge‐Localized States in an Antiferromagnet Topological Insulator NdBi
Advanced Science, EarlyView.Using spin‐polarized scanning tunneling microscopy (STM) in conjunction with quasiparticle interference, we successfully identify distinct signatures of the ferromagnetic and antiferromagnetic terminations in NdBi, a rare‐earth monopnictide exhibiting non‐trivial topology and magnetism. We demonstrate that step edges on ferromagnetic surfaces host well‐

Engineering topological phases in the Luttinger semimetal $\alpha$-Sn
, 2018 $\alpha$-Sn is well known as a typical Luttinger semimetal with a quadratic band touching at the $\Gamma$ point. Based on the effective $k\cdot p$ analysis as well as first-principles calculations, we demonstrate that multiple topological phases with a ...

Advanced Science, EarlyView.First‐principles calculations reveal that monolayer In2O${\rm In}_2{\rm O}$ hosts type‐II Dirac fermions near the Fermi level, which split into Weyl points under spin‐orbit coupling. The material exhibits negative and giant magnetoresistance, a pronounced spin Hall effect, and phonon‐mediated superconductivity at 1.5 K, establishing it as a unique ...

Chiral magnetic effect without chirality source in asymmetric Weyl semimetals
, 2018 We describe a new type of the Chiral Magnetic Effect (CME) that should occur in Weyl semimetals with an asymmetry in the dispersion relations of the left- and right-handed chiral Weyl fermions.

Quantum Nanomedicine and Quantum Biomaterials
Advanced Science, EarlyView.In this perspective, we define quantum nanomedicine and quantum biomaterials as a paradigm that harnesses quantum effects in nanomedicine and biomaterials, including quantum superposition, quantum coherence, quantum tunneling, topological quantum effects, and spin polarization, to achieve either spatiotemporally precise modulation of physiological ...

Intrinsic coupling between spatially-separated surface Fermi-arcs in Weyl orbit quantum Hall states
Nature Communications, 2021 The spatial distribution of the quantized transport due to the presence of Weyl orbits in topological semimetals remains elusive. Here, the authors report concomitant modulation of doubly-degenerate quantum Hall states, evidencing intrinsic coupling ...

Emergence of Double‐Dome Superconductivity in the Pressurized Dirac Semimetal BaMg2Bi2
Advanced Electronic Materials, EarlyView.ABSTRACT Dirac semimetal BaMg2${\rm BaMg}_{2}$Bi2${\rm Bi}_{2}$ is reported to be a unique topological material that manifests surface superconductivity that coexists with bulk band topology at ambient pressure. Here, we present a comprehensive investigation of high‐pressure superconducting properties in BaMg2${\rm BaMg}_{2}$Bi2${\rm Bi}_{2}$ single ...
