Unexpected stabilization of a single- charge density wave in pristine 1T-TiSe
Kimoon Higashihira Han, Dongju Hwang, Dongsin Kim +16
Over the past decade, studies revisiting the classical charge-density-wave system 1T-TiSe, long understood to host the triple- order with equivalent subcomponen…
Pseudogap in a crystalline insulator doped by disordered metals
Sae Hee Ryu, Minjae Huh, Do Yun Park +4
A key to understand how electrons behave in crystalline solids is the band structure that connects the energy of electron waves to their wavenumber (k). Even in the phase of matter…
Anomalous excitonic phase diagram in band-gap-tuned Ta2Ni(Se,S)5
Cheng Chen, Weichen Tang, Xiang Chen +17
During a band-gap-tuned semimetal-to-semiconductor transition, Coulomb attraction between electrons and holes can cause spontaneously formed excitons near the zero-band-gap point,…
Nature of the current-induced insulator-to-metal transition in CaRuO as revealed by transport-ARPES
Cissy T Suen, Igor Marković, Marta Zonno +21
The Mott insulator CaRuO exhibits a rare insulator-to-metal transition (IMT) induced by DC current. While structural changes associated with this transition have been track…
Spectral Evidence for Local-Moment Ferromagnetism in van der Waals Metals FeGaTe and FeGeTe
Han Wu, Chaowei Hu, Yaofeng Xie +26
Magnetism in two-dimensional (2D) materials has attracted considerable attention recently for both fundamental understanding of magnetism and their tunability towards device applic…
Nature of charge density wave in kagome metal ScV6Sn6
Seongyong Lee, Choongjae Won, Jimin Kim +9
Kagome lattice materials offer a fertile ground to discover novel quantum phases of matter, ranging from unconventional superconductivity and quantum spin liquids to charge orders…
