Topological properties and the dynamical crossover from mixed-valence to Kondo-lattice behavior in golden phase of SmS
Chang-Jong Kang, Hong Chul Choi, Kyoo Kim +1
We have investigated temperature-dependent behaviors of electronic structure and resistivity in a mixed-valent golden phase of SmS, based on the dynamical mean-field theory band st…
Dimerization-Induced Fermi-Surface Reconstruction in IrTe2
Man Jin Eom, Kyoo Kim, Y. J. Jo +6
We report a de Haas-van Alphen (dHvA) oscillation study on IrTe2 single crystals showing complex dimer formations. By comparing the angle dependence of dHvA oscillations with band…
The coexistence of charge density wave and superconductivity in Pt-based layered superconductors : SrPtAs and LaPtSi
Sooran Kim, Kyoo Kim, B. I. Min
The intriguing coexistence of the charge density wave (CDW) and superconductivity in SrPtAs and LaPtSi has been investigated based on the {\it ab initio} density fu…
Termination-dependent Surface In-gap States in a Mixed-valent Topological Insulator: SmB
Junwon Kim, Kyoo Kim, Chang-Jong Kang +5
We have investigated the surface states of a potential mixed-valent topological insulator SmB based on the first principles density functional theory slab band structure analys…
Universal metastability of the low-spin state in Co systems: non-Mott type pressure-induced spin-state transition in CoCl
Bongjae Kim, Kyoo Kim, B. I. Min
We have investigated the pressure-induced spin-state transition in Co systems in terms of a competition between the Hund's exchange energy () and the crystal-field splitt…
Structural instability and the Mott-Peierls transition in a half-metallic hollandite : KCrO
Sooran Kim, Kyoo Kim, B. I. Min
In order to explore the driving mechanism of the concomitant metal-insulator and structural transitions in quasi-one-dimensional hollandite KCrO, electronic stru…
