Hydrostatic Pressure-Induced Evolution of the Superconducting Transition Temperature of Bi-2212: Insights from First-Principles Calculations
Shuhong Tang, Hanyu Wang, Di Peng +3
High-pressure experiments on BiSrCaCuO (Bi-2212) have reported apparently conflicting evolutions of the superconducting transition temperature , ranging fr…
Bulk superconductivity up to 96 K in pressurized nickelate single crystals
Feiyu Li, Zhenfang Xing, Di Peng +24
Recently, the Ruddlesden-Popper bilayer nickelate has emerged as a superconductor with a transition temperature () of approximately 80 K above 14 GPa (Refs. 1-3)…
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…
Reply to "Threefold error in the reported zero-field cooled magnetic moment of single crystal (arXiv: 2602.23240)"
Feiyu Li, Zhenfang Xing, Di Peng +24
We respond to the critique by Aleksandr V. Korolev and Evgeny F. Talantsev on the superconducting phase fraction () calculations in Li et al. Nature 649, 871-878 (2026). First,…
