Large-gap insulating dimer ground state in monolayer IrTe2
Jinwoong Hwang, Kyoo Kim, Canxun Zhang +11
Monolayers of two-dimensional van der Waals materials exhibit novel electronic phases distinct from their bulk due to the symmetry breaking and reduced screening in the absence of…
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…
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…
Competing magnetic interactions in spin-1/2 square lattice: hidden order in SrVO
Bongjae Kim, Sergii Khmelevskyi, Peter Mohn +1
With decreasing temperature SrVO undergoes two structural phase transitions, tetragonal-to-orthorhombic-to-tetragonal, without long-range magnetic order. Recent experiments…
