Strong electron correlations and ligand hybridization for altermagnetism
Byungkyun Kang, Anderson Janotti, Dai Q. Ho +5
Spin-band splitting is a hallmark of altermagnetism, intrinsically linked to magnetic ordering driven by electron correlations. However, recent inconsistencies in the detection of…
QAssemble: A Pure Python Package for Quantum Many-Body Theory
Seongjun Mo, Dongming Li, Mancheon Han +5
QAssemble is a pure-Python package for the quantum many-body problem. It implements various functional approaches, such as tight-binding, Hartree-Fock, and GW approximations within…
Resonance-enhanced super-superexchange yields giant chiral magnon splitting in rutile altermagnets
Dai Q. Ho, D. Quang To, Byungkyun Kang +3
Altermagnets host momentum-selective spin splitting and chiral-split magnonic excitations despite vanishing net magnetization, enabling spin transport without ferromagnetism. In ru…
Hund's physics extends to actinide f electron systems
Byungkyun Kang, Roy N. Herrera-Navarro, Stephen S. Micklo +2
Uranium 5f electrons often yield heavy-fermion behavior via Kondo screening. However, the pronounced bad-metallic transport of uranium mononitride (UN) defies an incoherent Kondo e…
Lifshitz transition in correlated topological semimetals
Byungkyun Kang, Myoung-Hwan Kim, Chul Hong Park +2
Topological quasiparticles, arising when the chemical potential is near the band crossing, are pivotal for the development of next-generation quantum devices. They are expected to…
GPR_calculator: An On-the-Fly Surrogate Model to Accelerate Massive Nudged Elastic Band Calculations
Isaac Onyango, Byungkyun Kang, Qiang Zhu
We present GPR_calculator, a package based on Python and C++ programming languages to build an on-the-fly surrogate model using Gaussian Process Regression (GPR) to approximate exp…
Coexistence of 3D and quasi-2D Fermi surfaces driven by orbital selective Kondo scattering in UTe
Byungkyun Kang, Myoung-Hwan Kim, Chul Hong Park
The 3D Fermi surface, along with a chiral in-gap state and a Majorana zero energy state, is suggested to play a crucial role in the topologically nontrivial superconductivity in UT…
Semiconducting Electrides Derived From Sodalite: A First-principles Study
Chang Liu, Mahfuza Mukta, Byungkyun Kang +1
Electrides are ionic crystals with electrons acting as anions occupying well-defined lattice sites. These exotic materials have attracted considerable attention in recent years for…
Topological singularity-induced Mott-like self-energy and its impact on Kondo cloud formation
Byungkyun Kang, Zachary Brown, Myoung-Hwan Kim +2
We discovered that abnormal Mott physics can emerge even in weakly correlated 4f fermions through their interplay with topological singularity. Employing ab initio many-body pertur…
Crystallographic defects in Weyl semimetal LaAlGe
Inseo Kim, Byungkyun Kang, Hyunsoo Kim +1
Crystallographic defects in a topological semimetal can result in charge doping, and the scattering due to the defects may mask its exotic transport properties. Here, we investigat…
Mott transition and abnormal instability of electronic structure in FeSe
Byungkyun Kang, Maengsuk Kim, Chul Hong Park +1
FeSe has been extensively explored as a quantum material, primarily due to the observed highest superconducting transition temperature among Fe-based unconventional superconductors…
ComDMFT v.2.0: Fully Self-Consistent ab initio GW+EDMFT for the Electronic Structure of Correlated Quantum Materials
Byungkyun Kang, Patrick Semon, Corey Melnick +5
ComDMFT is a parallel computational package designed to study the electronic structure of correlated quantum materials from first principles. Our approach is based on the combinati…
