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…
All-to-All interactions via multifractal wavefunction geometry
YouYoung Joung, Jemin Park, SungBin Lee
We uncover a generic mechanism through which the intrinsic geometry of multifractal quantum wavefunctions generates effective all-to-all interactions in many-body systems. By analy…
Spatial correlations of charge density wave order across the transition in 2H-NbSe2
Seokjo Hong, Jaewhan Oh, Jemin Park +7
Charge density waves (CDWs) involve coupled amplitude and phase degrees of freedom, but direct access to local amplitude correlations remains experimentally challenging. Here, we r…
Proof of nonintegrability of the spin- bilinear-biquadratic chain model
HaRu K. Park, SungBin Lee
Spin- chain models have been extensively studied in condensed matter physics, significantly advancing our understanding of quantum magnetism and low-dimensional systems, which e…
