Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-7 (2024)
Abstract Atomic monolayers on semiconductor surfaces represent an emerging class of functional quantum materials in the two-dimensional limit — ranging from superconductors and Mott insulators to ferroelectrics and quantum spin Hall insulators. Ind

Visualizing band selective enhancement of quasiparticle lifetime in a metallic ferromagnet
Autor: Na Hyun Jo, Yun Wu, Thaís V. Trevisan, Lin-Lin Wang, Kyungchan Lee, Brinda Kuthanazhi, Benjamin Schrunk, S. L. Bud’ko, P. C. Canfield, P. P. Orth, Adam Kaminski
Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-7 (2021)
The onset of a ferromagnetic order in metals is often accompanied by a drop in resistivity; however, its effect on electronic quasiparticles is less understood. Here the authors present spectroscopic evidence of quasiparticle lifetime enhancement bel

Discovery of a weak topological insulating state and van Hove singularity in triclinic RhBi2
Autor: Kyungchan Lee, Gunnar F. Lange, Lin-Lin Wang, Brinda Kuthanazhi, Thaís V. Trevisan, Na Hyun Jo, Benjamin Schrunk, Peter P. Orth, Robert-Jan Slager, Paul C. Canfield, Adam Kaminski
Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-8 (2021)
Weak topological insulators (WTI) remain difficult to be observed in experiments. Here, the authors discover a WTI state in RhBi2, where the topological surface states with saddle points result in a van Hove singularity along the (100) direction near

A Meta-Analysis: Coronary Artery Calcium Score and COVID-19 Prognosis
Autor: Kevin Kyungmin Lee, Osman Rahimi, Charlie Kyungchan Lee, Amaan Shafi, Dalia Hawwass
Publikováno v: Medical Sciences, Vol 10, Iss 1, p 5 (2022)
Background: Multiple studies have investigated the correlations of mortality, mechanical ventilation, and intensive care unit (ICU) admissions with CAC scores. This analysis overviews the prognostic capability of CAC scoring in mortality, mechanical

Electronic signatures of successive itinerant, antiferromagnetic transitions in hexagonal La2Ni7
Autor: Kyungchan Lee, Na Hyun Jo, Lin-Lin Wang, R A Ribeiro, Yevhen Kushnirenko, Ben Schrunk, Paul C Canfield, Adam Kaminski
Publikováno v: Journal of Physics: Condensed Matter. 35:245501
We use high-resolution angle-resolved photoemission spectroscopy (ARPES) and density functional theory (DFT) calculations to study the electronic and magnetic properties of La2Ni7, an itinerant magnetic system with a series of three magnetic transiti

Emergence of Fermi arcs and novel magnetic splitting in an antiferromagnet
Autor: Benjamin Schrunk, Yevhen Kushnirenko, Brinda Kuthanazhi, Junyeong Ahn, Lin-Lin Wang, Evan O’Leary, Kyungchan Lee, Andrew Eaton, Alexander Fedorov, Rui Lou, Vladimir Voroshnin, Oliver J. Clark, Jaime Sánchez-Barriga, Sergey L. Bud’ko, Robert-Jan Slager, Paul C. Canfield, Adam Kaminski
Publikováno v: Nature
The Fermi arcs are signatures of exotic states in solids because they defy conventional concept of Fermi surfaces as closed contours in momentum space. Fermi arcs were first discovered in cuprates, and caused by the pseudogap. Weyl semimetals provide
