Lifted electron pocket and reversed orbital occupancy imbalance in FeSe
Soonsang Huh, Jeongjin Seo, Beomseo Kim +13
The FeSe nematic phase has been the focus of recent research on iron based superconductors (IBSs) due to its unique properties. A number of electronic structure studies were perfor…
Microscopic mechanism for asymmetric charge distribution in Rashba-type surface states and the origin of the the energy splitting scale
Beomyoung Kim, Panjin Kim, Wonsig Jung +9
Microscopic mechanism for the Rashba-type band splitting is examined in detail. We show how asymmetric charge distribution is formed when local orbital angular momentum (OAM) and c…
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…
Spin and Orbital Angular Momentum Structures of Cu(111) and Au(111) Surface States
Beomyoung Kim, Choong H. Kim, Panjin Kim +9
We performed angle resolved photoemission (ARPES) studies on Cu(111) and Au(111) surface states with circularly polarized light. Existence of local orbital angular momentum (OAM) i…
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…
