Multiferroic-enabled magnetic exciton in 2D quantum entangled van der Waals antiferromagnet NiI2
Suhan Son, Youjin Lee, Jae Ha Kim +15
Matter-light interaction is at the center of diverse research fields from quantum optics to condensed matter physics, opening new fields like laser physics. A magnetic exciton is o…
The field-angle anisotropy of proximate Kitaev systems under an in-plane magnetic field
Beom Hyun Kim
We have investigated the field-angle behaviors of magnetic excitations under an in-plane magnetic field for proximate Kitaev systems. By employing the exact diagonalization method…
Exciton-driven antiferromagnetic metal in a correlated van der Waals insulator
Carina A. Belvin, Edoardo Baldini, Ilkem Ozge Ozel +11
Collective excitations of bound electron-hole pairs -- known as excitons -- are ubiquitous in condensed matter, emerging in systems as diverse as band semiconductors, molecular cry…
Interplay between multipolar spin interactions, Jahn-Teller effect and electronic correlation in a insulator
Dario Fiore Mosca, Leonid V. Pourovskii, Beom Hyun Kim +5
In this work we study the complex entanglement between spin interactions, electron correlation and Janh-Teller structural instabilities in the 5d spin-orb…
Proximate Kitaev system for an intermediate magnetic phase in in-plane magnetic fields
Beom Hyun Kim, Shigetoshi Sota, Tomonori Shirakawa +2
Motivated by the magnetic phase transition of a proximate Kitaev system -RuCl in the presence of a magnetic field, we study the simplest but essential quantum spin model wit…
Topological property of a system with a honeycomb lattice structure
Beom Hyun Kim, Kazuhiro Seki, Tomonori Shirakawa +1
A system with a honeycomb lattice structure such as NaIrO was firstly proposed as a topological insulator even though NaIrO and its isostructural materia…
