“Electron-Phonon Coupling in Doped KTaO3 Does Not Align with Experimental Critical Temperatures, Hinting at Non-BCS Superconductivity”

https://pubmed.ncbi.nlm.nih.gov/38115952

The electron-phonon coupling in doped KTaO3, calculated through first-principles, does not align with experimentally measured critical temperatures, suggesting a non-BCS character of superconductivity.
