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.…
Multi-orbital effects on superconductivity in kagome metals: Parquet renormalization group analysis
Jae-Ho Han, SungBin Lee
The Van Hove singularities (VHSs), where the electronic density of states diverges due to saddle points in the band structure, play a crucial role in enhancing electronic correlati…
Electric Control of Polarity in Spin-Orbit Josephson Diode
Junghyun Shin, Jae-Ho Han, Anjali Rathore +5
The effect of spin-orbit coupling in a Josephson diode has not been elucidated due to its interplay with the complexity of Josephson devices. Here, we systematically control local…
Symmetry-protected flatband condition for Hamiltonians with local symmetry
Jung-Wan Ryu, Alexei Andreanov, Hee Chul Park +1
We derive symmetry-based conditions for tight-binding Hamiltonians with flatbands to have compact localized eigenstates occupying a single unit cell. The conditions are based on un…
Exceptional Classifications of Non-Hermitian Systems
Jung-Wan Ryu, Jae-Ho Han, Chang-Hwan Yi +2
Eigenstate coalescence in non-Hermitian systems is widely observed in diverse scientific domains encompassing optics and open quantum systems. Recent investigations have revealed t…
Tunable electronic and magnetic phases in layered ruthenates: SrRuO3-SrTiO3 heterostructure upon strain
Minjae Kim, Chang-Jong Kang, Jae-Ho Han +2
Layered ruthenates are a unique class of systems which manifests a variety of electronic and magnetic features emerged from competing energy scales. At the heart of such features l…
