Tags: Tokyo Institute of Technology, Japan, Electronics & Robotics, Computing Technology
Tokyo Tech researchers have leveraged the thermoelectric effect to detect weak fluctuations in superconductivity across broad magnetic fields and temperatures, revealing a comprehensive view of superconductor behavior. By observing these fluctuations, the team has confirmed a quantum critical point, explaining the long-unresolved anomalous metallic state in two-dimensional superconductors. This breakthrough provides deeper insight into quantum fluctuations at extremely low temperatures, crucial for understanding superconductor-insulator transitions. Applications of this technology include enhanced cooling systems and other low-temperature technologies. The results illuminate fundamental aspects of superconductivity, potentially influencing materials science and quantum computing.
