Strain-tuned orbital-dependent electronic correlations in FeTe thin films
Hyunjee Song, Sangjae Lee, Keun-Yeol Park +8
Iron chalcogenides exhibit rich phenomena which are governed by orbital-dependent electronic interactions and strong electronic correlation. In particular, many studies have explor…
Fragility of Topology under Electronic Correlations in Iron Chalcogenides
Younsik Kim, Junseo Yoo, Sehoon Kim +5
The interplay between electronic correlations and topology is a central topic in the study of quantum materials. In this work, we investigate the impact of the orbital-selective Mo…
Probabilistic denoising for reliable signal extraction in spectroscopy
Younsik Kim, Changyoung Kim
While deep learning offers powerful capabilities for scientific research, its application is often hindered by a lack of quantitative reliability. To address this, we introduce a p…
Plasmon-driven exciton formation in a non-equilibrium Fermi liquid
Rishi Acharya, Eli Gerber, Nina Bielinski +13
Collective modes in Fermi liquids are usually regarded as dissipation channels that relax electronic excitations through Landau damping. Whether such modes can instead mediate the…
Magnetic-fluctuation-driven suppression of spin-orbit hybridization in the surface ferromagnet GdAg/Ag(111)
Ryo Noguchi, Jongkeun Jung, Younsik Kim +2
Magnetic materials hosting topological band structures have attracted intense interest due to the interplay between magnetism and spin-orbit coupling (SOC). Here, using temperature…
Coexisting Kagome and Heavy Fermion Flat Bands in YbCrGe
Hanoh Lee, Churlhi Lyi, Taehee Lee +16
Flat bands, emergent in strongly correlated electron systems, stand at the frontier of condensed matter physics, providing fertile ground for unconventional quantum phases. Recent…
