Temperature Evolution of Itinerant Ferromagnetism in SrRuO3 Probed by Optical Spectroscopy
D. W. Jeong, Hong Chul Choi, Choong H. Kim +12
The temperature () dependence of the optical conductivity spectra of a single crystal SrRuO thin film is studied over a range from 5 to 450 K. We observed signifi…
Dimensional crossover of the electronic structure in LaNiO3 ultrathin films: Orbital reconstruction, Fermi surface nesting, and the origin of the metal-insulator transition
Hyang Keun Yoo, Seung Ill Hyun, Luca Moreschini +9
Dimensionality control in the LaNiO3 (LNO) heterostructure has attracted attention due to its two-dimensional (2D) electronic structure was predicted to have an orbital ordered ins…
Correlated Electronic Structures and the Phase Diagram of Hydrocarbon-based Superconductors
Minjae Kim, B. I. Min, Hong Chul Choi +1
We have investigated correlated electronic structures and the phase diagram of electron-doped hydrocarbon molecular solids, based on the dynamical mean-field theory. We have found…
Kink during the formation of the Kondo resonance band in the heavy fermion system
Hong Chul Choi, K. Haule, G. Kotliar +2
We have investigated the formation of the Kondo resonance (KR) band and the hybridization gap (HG) in the heavy fermion compound CeCoGe2, using a combined approach of the density f…
Anisotropic Dirac electronic structures of AMnBi (A=Sr, Ca)
Geunsik Lee, Muhammad A. Farhan, Jun Sung Kim +1
Low energy electronic structures in AMnBi2 (A=alkaline earths) are investigated using a first-principles calculation and a tight binding method. An anisotropic Dirac dispersion is…
