The evolution of the Eliashberg function α 2F(ω) and corresponding Tc (inset) is optimized. Red (green) lines are later (earlier) iterations in the optimization. Credit: arXiv (2024). DOI: 10.48550/arxiv.2406.08129 In a new development that could help redefine the future of technology, a team of physicists has uncovered a fundamental insight into the upper limit of superconducting temperature. This research, accepted for publication in the Journal of Physics: Condensed Matter, suggests that room...
