Novel =3/2 Metallic Phase and Unconventional Superconductivity in GaTaSe
Min Yong Jeong, Seo Hyoung Chang, Hyeong Jun Lee +10
By means of density functional theory plus dynamical mean-field theory (DFT+DMFT) calculations and resonant inelastic x-ray scattering (RIXS) experiments, we investigate the high-p…
Correlation effects on 3D topological phases: from bulk to boundary
Ara Go, William Witczak-Krempa, Gun Sang Jeon +2
Topological phases of quantum matter defy characterization by conventional order parameters but can exhibit quantized electro-magnetic response and/or protected surface states. We…
Interplay between spin-orbit coupling and van Hove singularity in the Hund's metallicity of SrRuO
Hyeong Jun Lee, Choong H. Kim, Ara Go
We investigate the dynamical properties of SrRuO at zero and very low temperature using density functional theory plus dynamical mean-field theory with an exact diagonaliza…
Honeycomb-Lattice Mott insulator on Tantalum Disulphide
Jinwon Lee, Kyung-Hwan Jin, Andrei Catuneanu +8
Effects of electron many-body interactions amplify in an electronic system with a narrow bandwidth opening a way to exotic physics. A narrow band in a two-dimensional (2D) honeycom…
Identification of a Kitaev Quantum Spin Liquid by Magnetic Field Angle Dependence
Kyusung Hwang, Ara Go, Ji Heon Seong +2
Quantum spin liquids realize massive entanglement and fractional quasiparticles from localized spins, proposed as an avenue for quantum science and technology. In particular, topol…
Properties of the one-dimensional Hubbard model: cellular dynamical mean-field description
Ara Go, Gun Sang Jeon
The one-dimensional half-filled Hubbard model is considered at zero temperature within the cellular dynamical mean-field theory (CDMFT). By the computation of the spectral gap and…
