Spin Fluctuations in SrLaRuO
Zheng He, Qisi Wang, Yu Feng +12
We use inelastic neutron scattering to study spin fluctuations in SrLaRuO, where Lanthanum doping triggers a Lifshitz transition by pushing the van Hove singula…
Electric field driven octahedral rotation in perovskite
Wonshik Kyung, Choong H. Kim, Yeong Kwan Kim +9
Rotation of MO6 (M = transition metal) octahedra is a key determinant of the physical properties of perovskite materials. Therefore, tuning physical properties, one of the most imp…
Observation of warping effects in the band and angular momentum structures of topological insulator Bi2Te3
Wonsig Jung, Yeongkwan Kim, Beomyoung Kim +10
We performed angle resolved photoemission (ARPES) experiments on Bi2Te3 with circularly polarized light. ARPES data show very strong circular dichroism, indicating existence of orb…
Anisotropic Dirac fermions in a Bi square net of SrMnBi2
Joonbum Park, G. Lee, F. Wolff-Fabris +8
We report the highly anisotropic Dirac fermions in a Bi square net of SrMnBi2, based on a first principle calculation, angle resolved photoemission spectroscopy, and quantum oscill…
Chiral orbital-angular-momentum in the surface states of Bi2Se3
Seung Ryong Park, Jinhee Han, Chul Kim +11
Locking of the spin of a quasi-particle to its momentum in split bands of on the surfaces of metals and topological insulators (TIs) is understood in terms of Rashba effect where a…
Electronic Structure Studies of Detwinned BaFeAs by Photoemission
Y. K. Kim, Hyungju Oh, Chul Kim +10
We performed angle resolved photoelectron spectroscopy (ARPES) studies on mechanically detwinned BaFe2As2. We observe clear band dispersions and the shapes and characters of the Fe…
