Electronic and chemical phase identification in photoemission experiments using unsupervised machine learning
Matthew Staab, Joseph Pandur, Eli Rotenberg +3
Vacuum ultraviolet photoemission spectroscopies are very information-rich experiments, but due to their surface sensitivity, data are often collected on an initially uncharacterize…
Revealing the Electronic Structure of van der Waals Antiferromagnetic NiPS through Synchrotron-Based -ARPES and Alkali Metal Dosing
Yifeng Cao, Qishuo Tan, Yucheng Guo +13
This study presents a comprehensive analysis of the band structure in NiPS, a van der Waals layered antiferromagnet, utilizing high-resolution synchrotron-based angle-resolved…
Spin Excitations and Flat Electronic Bands in a Cr-based Kagome Superconductor
Zehao Wang, Yucheng Guo, Hsiao Yu Huang +33
In the quest for topology- and correlation-driven quantum states, kagome lattice materials have garnered significant interest for their band structures, featuring flat bands (FBs)…
Mesoscale variations of chemical and electronic landscape on the surface of Weyl semimetal CoSnS visualized by ARPES and XPS
Sudheer Anand Sreedhar, Matthew Staab, Mingkun Chen +14
The multiple crystalline terminations in magnetic Weyl semimetal CoSnS display distinct topological and trivial surface states, which have successfully been distinguish…
Local interface effects modulate global charge order and optical properties of 1T-TaS/1H-WSe heterostructures
Samra HusremoviÄ, Valerie S. McGraw, Medha Dandu +14
1T-TaS is a layered charge density wave (CDW) crystal exhibiting sharp phase transitions and associated resistance changes. These resistance steps could be exploited for inform…
Dark states of electrons in a quantum system with two pairs of sublattices
Yoonah Chung, Minsu Kim, Yeryn Kim +14
A quantum state of matter that is forbidden to interact with photons and is therefore undetectable by spectroscopic means is called a dark state. This basic concept can be applied…
