Physics-informed Machine Learning Prediction of Hubbard Interaction Parameters
Jiyeon Kim, Indukuru Ramesh Reddy, Bongjae Kim +1
Accurate determination of Hubbard interaction parameters is essential for beyond-DFT approaches such as DFT+, DFT+DMFT, and DFT++ in correlated materials. In practice, how…
Unconventional Mixed-Parity Magnetism in Rare-Earth Tetraborides
Dong-Choon Ryu, Jae-Ho Han, Bongjae Kim +1
Altermagnetism has advanced the study of compensated magnets by revealing non-relativistic spin splitting, traditionally classified into strictly even- or odd-parity spin textures.…
Strain Engineering of van Hove Singularity and Coupled Itinerant Ferromagnetism in Quasi-2D Oxide Superlattices
Seung Gyo Jeong, Minjae Kim, Jin Young Oh +12
Engineering van Hove singularities (vHss) near the Fermi level, if feasible, offers a powerful route to control exotic quantum phases in electronic and magnetic behaviors. However,…
Correlation Effects on Magnetic Structure and Lattice Dynamics of LaMnO: A First-Principles Study
Haeyoon Jung, Indukuru Ramesh Reddy, Bongjae Kim +2
LaMnO, a quadruple perovskite oxide (AA'BO-type), has attracted attention for its notable bifunctional activity in oxygen evolution and reduction reaction…
Role of On-site and Inter-site Coulomb Interactions in KVSb: A first-principles DFT++ study
Indukuru Ramesh Reddy, Sayandeep Ghosh, Bongjae Kim +1
Nonlocal Coulomb interactions play a crucial role in stabilizing distinct electronic phases in kagome materials. In this work, we systematically investigate the effects of on-site…
Comparative analysis of methods for calculating Hubbard parameters using cRPA
Indukuru Ramesh Reddy, M. Kaltak, Bongjae Kim
In this study, we present a systematic comparison of various approaches within the constrained random-phase approximation (cRPA) for calculating the Coulomb interaction parameter $…
Weyl Fermion with various chiralities in a f-electron ferromagnetic system: PrB4
Dong-Choon Ryu, Junwon Kim, Kyoo Kim +3
Rare-earth tetraborides (B) have attracted a lot of recent attention due to their intriguing electronic, magnetic, and topological properties. We have theoretically invest…
Exploring the role of nonlocal Coulomb interactions in perovskite transition metal oxides
Indukuru Ramesh Reddy, Chang-Jong Kang, Sooran Kim +1
Employing the density functional theory incorporating on-site and inter-site Coulomb interactions (DFT+U+V), we have investigated the role of the nonlocal interactions on the elect…
