Abstract: Significance Achieving higher transition temperature (T c ) is a primary goal in superconductivity research. T c and doping have been found to have a dome-like universal relation where the peak position is the maximum T c-max , which is consistent with previous experimental results in the lower pressure range. By using the ultrasensitive magnetization measurement technique under high pressure that we developed, we discovered a universal resurgence of T c passing the peak predicted by the general T c - p (doping) or -P (pressure) relation for cuprate high-temperature superconductor and attribute the resurgence to a pressure-induced electronic transition, which is supported qualitatively by our density functional theory calculations. This offers a paradigm to raise the T c of the layered cuprate high-temperature superconductors to a new height.
