Xu Chen, Tao Sun, Huifen Ren +4
The paper describes the Sample Pre‑selection and Characterization Station at the SECUF, detailing its instrumentation for synthesizing, processing, and characterizing samples befor…
Emergent interweaved CDW unoccupied states in hole-doping LaTe2 with element substitution
Shuya Xing, Hongyu Liu, Xu Chen +6
The paper reports low‑temperature STM observations of three interweaved charge‑density‑wave wave vectors in hole‑doped LaTe2‑xSbx, linking them to nesting of px and py bands and id…
Anomalous charge density wave in a two-dimensional superatomic superconductor
Boqin Song, Shuaishuai Sun, Zhongxu Wei +12
The spatial modulation of electron density into a wave-like pattern, known as charge density wave (CDW), represents a fundamental quantum state that often coexists with superconduc…
Bragg-Williams order competes with superconductivity
Xu Liu, Xu Chen, Chuizhen Chen +14
Orderings in charge and spin have been extensively studied to unravel their correlation to emergent superconductivity over the past decades. Bragg-Williams order (BWO), a classical…
On estimating superconducting shielding volume fraction from susceptibility in pressurized Ruddlesden-Popper nickelates: Response to arXiv:2602.19282
Yinghao Zhu, Di Peng, Enkang Zhang +10
In a recent preprint (arXiv:2602.19282) [1], the authors questioned the procedure we used to evaluate the demagnetization-corrected superconducting shielding volume fraction in pre…
Charge-polarized superconducting state emerging in a superatomic antipolar metal
Shuya Xing, Zhongxu Wei, Xu Chen +17
The simultaneous presence of polarity and metallicity or superconductivity in a material signifies the exotic polar metallic or superconducting (SC) state, while such materials are…
