A high-temperature superconductor with zero resistance that exhibits strange metal behavior

https://phys.org/news/2024-06-high-temperature-superconductor-resistance-strange.html

"Ruddlesden–Popper Bilayer Nickelate high-temperature superconductivity, no resistance, strange metal behavior exhibiting unconventional superconductivity and/or 0-temperature quantum phase transition not by tuning temperature, that cannot be described by our existing knowledge based on Landau's theorem... using tiny samples, better hydrostatic pressure conditions, applying liquid hydrostatic pressure in diamond anvil... making electrical contacts on 100mm length silver paste... 0 resistance at <40°K"
