Real-space charge distribution of the cobalt ion and its relation with charge and spin states
Bongjae Kim
The charge state of an ion provides a simplified electronic picture of the bonding in compounds, and heuristically explains the basic electronic structure of a system. Despite its…
Quantification of Coulomb Interactions in layered Lithium and Sodium Battery Cathode Materials
Bongjae Kim, Kyoo Kim, Sooran Kim
Despite the importance of the electron correlation in the first-principles description of the Li-ion cathode materials, the Coulomb interaction parameter, U is often treated as an…
Comparative ab initio study of the structural, electronic, magnetic, and dynamical properties of LiOsO and NaOsO
Peitao Liu, Jiangang He, Bongjae Kim +4
Despite similar chemical compositions, LiOsO and NaOsO exhibit remarkably distinct structural, electronic, magnetic, and spectroscopic properties. At low temperature, LiOsO…
SrRuO-SrTiO heterostructure as a possible platform for studying unconventional superconductivity in SrRuO
Bongjae Kim, Sergii Khmelevskyi, Cesare Franchini +2
There is intense controversy around the unconventional superconductivity in strontium ruthenate, where the various theoretical and experimental studies suggest diverse and mutually…
Magnetic field-induced type-II Weylsemimetallic state in geometrically frustrated Shastry-Sutherland lattice GdB4
Wonhyuk Shon, Dong-Choon Ryu, Kyoo Kim +6
Weyl semimetal is a topologically non-trivial phase of matter with pairs of Weyl nodes in the k-space, which act as monopole and anti-monopole pairs of Berry curvature. Two hallmar…
Osmates on the verge of a Hund's-Mott transition: The different fates of NaOsO and LiOsO
Daniel Springer, Bongjae Kim, Peitao Liu +6
We clarify the origin of the strikingly different spectroscopic properties of the chemically similar compounds NaOsO and LiOsO. Our first-principle many-body analysis demon…
