Hund's physics and the magnetic ground state of CrOX (X = Cl, Br)
Seung Woo Jang, Do Hoon Kiem, Juhyeok Lee +3
To understand the magnetic property of layered van der Waals materials CrOX (X = Cl, Br), we performed the detailed first-principles calculations for both bulk and monolayer. We fo…
On the origin and the manipulation of ferromagnetism in FeGeTe: defects and dopings
Seung Woo Jang, Min Yong Jeong, Hongkee Yoon +2
To understand the magnetic properties of FeGeTe, we performed the detailed first-principles study. Contrary to the conventional wisdom, it is unambiguously shown that Fe$_3…
Magnetic force theory combined with quasi-particle self-consistent GW method
Hongkee Yoon, Seung Woo Jang, Jae-Hoon Sim +2
We report a successful combination of magnetic force linear response theory with quasiparticle self-consistent GW method. The self-consistently determined wavefunctions and eigenva…
Microscopic understanding of magnetic interactions in bilayer CrI
Seung Woo Jang, Min Yong Jeong, Hongkee Yoon +2
We performed the detailed microscopic analysis of the inter-layer magnetic couplings for bilayer CrI. As the first step toward understanding the recent experimental observation…
Charge density functional plus theory of LaMnO: Phase diagram, electronic structure, and magnetic interaction
Seung Woo Jang, Siheon Ryee, Hongkee Yoon +1
We perform charge density functional theory plus calculation of LaMnO. While all the previous calculations were based on spin density functionals, our result and analysis s…
Reliability and applicability of magnetic force linear response theory: Numerical parameters, predictability, and orbital resolution
Hongkee Yoon, Taek Jung Kim, Jae-Hoon Sim +3
We investigated the reliability and applicability of so-called magnetic force linear response method to calculate spin-spin interaction strengths from first-principles. We examined…
Model-mapped RPA for determining the effective Coulomb interaction
Hirofumi Sakakibara, Seung Woo Jang, Hiori Kino +3
We present a new method to obtain interaction part of a model Hamiltonian from the result of the first-principles calculation. The effective interaction contained in the model is d…
Direct theoretical evidence for weaker correlations in electron-doped and Hg-based hole-doped cuprates
Seung Woo Jang, Hirofumi Sakakibara, Hiori Kino +3
Many important questions for high- cuprates are closely related to the insulating nature of parent compounds. While there has been intensive discussion on this issue, all argu…
Quasiparticle self-consistent GW calculation of SrRuO and SrRuO:
Hyeonsang Ryee, Seung Woo Jang, Hiori Kino +2
Using quasiparticle self-consistent calculations, we re-examined the electronic structure of SrRuO and SrRuO. Our calculations show that the correlation effects be…
Quasiparticle self-consistent GW study of cuprates: electronic structure, model parameters, and the two-band theory for Tc
Seung Woo Jang, Takao Kotani, Hiori Kino +2
Despite decades of progress, an understanding of unconventional superconductivity still remains elusive. An important open question is about the material dependence of the supercon…
