Nonresonant Inelastic X-Ray Scattering and Energy-Resolved Wannier Function Investigation of d-d Excitations in NiO and CoO
Ben C Larson,Wei Ku,Jonathan Zachary Tischler,Chi-Cheng Lee,Chi-Cheng Lee,Oscar D. Restrepo,Oscar D. Restrepo,Adolfo G. Eguiluz,Adolfo G. Eguiluz,Paul Zschack,Kenneth D. Finkelstein +10 more
TL;DR: Nonresonant inelastic x-ray scattering measurements on NiO and CoO show that strong dipole-forbidden d-d excitations appear within the Mott gap at large wave vectors, and the sensitivity to weak symmetry breaking in particle-hole wave functions suggests a wide application to strongly correlated systems.
Journal ArticleDOI
Unfolding method for first-principles LCAO electronic structure calculations
TL;DR: The unfolding method is generalized to the linear combination of atomic orbitals (LCAO) method, and a general formula to calculate the unfolded spectral weight is presented, showing the usefulness of the unfolding method.

Chenglong Zhang,Bingbing Tong,Chi-Cheng Lee,Junfeng Wang,Zhujun Yuan,M. Zahid Hasan,Shin-Ming Huang,Ilya Belopolski,Ziquan Lin,Nasser Alidoust,Shuang Jia,Su-Yang Xu,Titus Neupert,Daniel S. Sanchez,Hsin Lin,Madhab Neupane,Hao Zheng,Chi Zhang,Guang Bian +18 more
TL;DR: In this article, the experimental discovery of Adler-Bell-Jackiw chiral anomaly in a Weyl semimetal crystal was reported, which was later confirmed by the same authors.
Journal ArticleDOI
Signatures of Fermi Arcs in the Quasiparticle Interferences of the Weyl Semimetals TaAs and NbP.
Guoqing Chang,Su-Yang Xu,Hao Zheng,Chi-Cheng Lee,Shin-Ming Huang,Ilya Belopolski,Daniel S. Sanchez,Guang Bian,Nasser Alidoust,Tay-Rong Chang,Chuang-Han Hsu,Horng-Tay Jeng,Horng-Tay Jeng,Arun Bansil,Hsin Lin,M. Zahid Hasan +15 more
TL;DR: The results, for the first time, propose a universal interference signature of the topological Fermi arcs in TaAs, which is fundamental for scanning tunneling microscope (STM) measurements on this prototypical Weyl semimetal compound.

Coupling of spin and orbital excitations in the iron-based superconductor FeSe 0.5 Te 0.5
Seunghun Lee,Guangyong Xu,Wei Ku,Jinsheng Wen,Jinsheng Wen,Chi-Cheng Lee,Naoyuki Katayama,Zhijun Xu,Zhijun Xu,Sungdae Ji,Z. W. Lin,G. D. Gu,H.-B. Yang,Peter D. Johnson,Z.-H. Pan,Tonica Valla,Masaki Fujita,T. Sato,Sung Chang,Kohta Yamada,John M. Tranquada +20 more
TL;DR: In this paper, a combined analysis of neutron scattering and photoemission measurements on superconducting FeSe{sub 0.5}Te{sub0.5}. was presented, showing that low-energy magnetic excitations dispersed only in the direction transverse to the characteristic wave vector (1/2,0,0) whereas the electronic Fermi surface near (1 2,0,0) appears to consist of four incommensurate pockets.
