Ab initio screening of quantum frustrated materials with kagome and triangular geometries
Byeong-Hyeon Jeong, Hee Seung Kim, SungBin Lee +1
Geometrical frustration is a powerful route to realize exotic phases such as quantum spin liquids. Despite extensive efforts, systematic searches targeting specific frustration mot…
Spin Liquid Landscapes in the Kagome Lattice: A Variational Monte Carlo Study of the Chiral Heisenberg Model and Experimental Signatures
Hee Seung Kim, Hyeok-Jun Yang, Karlo Penc +1
Chiral spin liquids, which break time-reversal symmetry, are of great interest due to their topological properties and fractionalized excitations (anyons). In this work, we investi…
Crucial role of out-of-plane Sb- orbitals in Van Hove singularity formation and electronic correlation for superconducting Kagome metal CsVSb
Min Yong Jeong, Hyeok-Jun Yang, Hee Seung Kim +3
First-principles density functional theory calculations are performed to understand the electronic structure and interaction parameters for recently discovered superconducting Kago…
Intertwining orbital current order and superconductivity in Kagome metal
Hyeok-Jun Yang, Hee Seung Kim, Min Yong Jeong +3
The nature of superconductivity in newly discovered Kagome materials, (A=K, Rb, Cs), has been a subject of intense debate. Recent experiments suggest the p…
Partial Kondo Screening and Anomalous Thermal Conductance
Hee Seung Kim, Hyeok-Jun Yang, SungBin Lee
The frustrated magnetism on the Kondo lattice system motivates intriguing Kondo-breakdown beyond the traditional Doniach scenario. Among them, the fractionalized Fermi liquid (FL*)…
Emergent chiral spin ordering and anomalous Hall effect of kagome lattice at 1/3 filling

Magnetic field and thermal Hall effect in a pyrochlore U(1) quantum spin liquid
Hyeok-Jun Yang, Hee Seung Kim, SungBin Lee
The antiferromagnetic system on a rare-earth pyrochlore has been focused as a strong candidate of U(1) quantum spin liquid. Here, we study the phase transitions driven by external…
Emergent Localization in Dodecagonal Bilayer Quasicrystals
Moon Jip Park, Hee Seung Kim, SungBin Lee
A new type of long-range ordering in the absence of translational symmetry gives rise to drastic revolution of our common knowledge in condensed matter physics. Quasicrystal, as su…
