Unraveling the Enigma: Unveiling the Puzzling Behavior of Cuprates and its Superconductor Implications

Researchers have discovered a quantum critical point connected to the "strange metal" phase of high-critical-temperature copper-based superconductors. The study, based on X-ray scattering experiments, reveals the existence of charge density fluctuations that make cuprates behave like "strange" metals. This discovery could lead to the development of better materials with higher critical temperatures, advancing superconductivity research and contributing to sustainable technologies.
