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…
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…
Antiferromagnetic and structural transitions in the superoxide KO2 from first principles: A 2p-electron system with spin-orbital-lattice coupling
Minjae Kim, Beom Hyun Kim, Hong Chul Choi +1
KO2 exhibits concomitant antiferromagnetic (AFM) and structural transitions, both of which originate from the open-shell 2p electrons of O molecules. The structural trans…
Magnetic phase diagram of doped CMR manganites
Unjong Yu, Yookyung Jo, B. I. Min
The magnetic phase diagram of the colossal magnetoresistance (CMR) manganites is determined based on the Hamiltonian incorporating the double-exchange (DE) interaction between dege…
